The subject matter disclosed herein generally relates to machines configured to the technical field of special-purpose machines that facilitate machine-learning based modeling including computerized variants of such special-purpose machines and improvements to such variants, and to the technologies by which such special-purpose machines become improved compared to other special-purpose machines that facilitate machine-learning based modeling. Embodiments of the present disclosure relate generally to machine-learning based modeling and, more particularly, but not by way of limitation, to a method of generating a user interface enabling simultaneous modeling of data sets using and comparing variable machine-learning techniques.
Machine-learning processes are often useful in making predictions based on data sets. Users may want to explore a large data set using multiple variables in distinct models. Typically, in order to generate multiple distinct models on a single data set, the individual generates each model separately inputting variable changes for each distinct model. Further, in order to generate models from differing machine-learning techniques, users often need expertise in each machine-learning technique and use differing interfaces for each machine-learning technique.
Various ones of the appended drawings merely illustrate example embodiments of the present disclosure and cannot be considered as limiting its scope.
The headings provided herein are merely for convenience and do not necessarily affect the scope or meaning of the terms used.
The description that follows includes systems, methods, techniques, instruction sequences, and computing machine program products that embody illustrative embodiments of the disclosure. In the following description, for the purposes of explanation, numerous specific details are set forth in order to provide an understanding of various embodiments of the inventive subject matter. It will be evident, however, to those skilled in the art, that embodiments of the inventive subject matter may be practiced without these specific details. In general, well-known instruction instances, protocols, structures, and techniques are not necessarily shown in detail.
Example embodiments described herein disclose a comparative modeling system for performing modeling work. The comparative modeling system enables a user to utilize or view a consolidated set of steps to model, analyze, featurize, and vectorize data. The comparative modeling system also facilitates selection of models, iterative generation of models using selected data sets, comparison of models from multiple selected machine-learning or modeling algorithms, and tracking of input and results.
As an example, a user has a set of data and a thesis for machine-learning some portion of information from the set of data. The user wants to interact with multiple machine-learning models to identify a suitable or comparatively better machine-learning model or explore a new machine-learning model. The user establishes a machine-learning model to run on the set of data and to iteratively run on future data as the data is integrated into the set of data. The user takes guesses, adjusts model parameters, or, through selections in an interface, causes the comparative modeling system to automatically step through iterative modeling of the set of data using defined intervals. The settings for machine-learning models, in the comparative modeling system, may be hypo-parameters. User interface selections may enable the user to tune vectorization or featurization, or to iteratively try multiple options, automatically identifying suitable modeling results. For example, the user may model customer churn within a set of data to predict how many customers for a company will end a service given call logs, payment history, and other customer information. The comparative modeling system enables iterative processing of the data to identify variables, which have increased weight on churn decisions, churn likelihood, or timing of customer churn.
Examples merely typify possible variations. Unless explicitly stated otherwise, components and functions are optional and may be combined or subdivided, and operations may vary in sequence or be combined or subdivided. In the following description, for purposes of explanation, numerous specific details are set forth to provide a thorough understanding of example embodiments. It will be evident to one skilled in the art, however, that the present subject matter may be practiced without these specific details.

Further, while the network architecture 100 shown in
The access component 210 receives selections of data sets, transform schemes, and machine-learning or modeling algorithms. The access component 210 may receive or access the selections through a graphical user interface generated by one or more components of the comparative modeling system 150. The access component 210 may also receive, retrieve, or otherwise access data within one or more databases to fulfill requests or provide input for one or more components of the comparative modeling system 150 in generating models. In some embodiments, the access component 210 accesses sets of data using a network connection (e.g., the Internet) to connect to a database containing the set of data to be modeled.
The parameter component 220 determines or otherwise identifies parameters selected within a graphical user interface generated and presented by one or more components of the comparative modeling system 150. In some instances, the parameter component 220 determines parameters selected for machine-learning algorithms. The parameter component 220 may pass selections of parameters to one or more other components of the comparative modeling system 150 for processing of the set of data and generating models using the set of data. The parameter component 220 may perform validation checks to determine if selected parameters are compatible for use with respect to other selected parameters, selected transform schemes, and selected machine-learning algorithms. In some instances, in response to one or more selections (e.g., selection of a set of data and selection of a transform scheme), the parameter component 220 operates in cooperation with one or more of the access component 210 and the presentation component 250 to generate and present parameter selections within the graphical user interface.
The modeling component 230 generates models from selected sets of data modified by a selected transform scheme. The modeling component 230 generates one or more models based on one or more selected machine-learning algorithms. In some instances, the modeling component 230 generates a single model, an iterative model, or a plurality of models for a single set of data with respect to a single machine-learning algorithm. In some embodiments, the iterative model comprises a set of models, where each model is generated for a selected number of steps or other plurality of specified values for a selected machine-learning algorithm. The modeling component 230 may also generate one or more models for a single data set with respect to a plurality of selected machine-learning algorithms.

The presentation component 250 also generates and causes presentation of a graphical user interface configured to pass selections for sets of data, transform schemes, and machine-learning algorithms to the access component 210. In some instances, the presentation component 250 dynamically generates, regenerates, or modifies the graphical user interface based on selections received at a client device or through a user input device. The presentation component 250 may dynamically generate or modify the graphical user interface in response to changes to the set of data (e.g., data being updated or new data being added), a set of transform schemes (e.g., new transform schemes being added), and a set of machine-learning algorithms (e.g., machine-learning algorithms being added, removed, modified, or generating models).

Any one or more of the components described may be implemented using hardware alone (e.g., one or more of the processors of a machine) or a combination of hardware and software. For example, any component described in the comparative modeling system 150 may physically include an arrangement of one or more processors (e.g., a subset of or among the one or more processors of the machine) configured to perform the operations described herein for that component. As another example, any component of the comparative modeling system 150 may include software, hardware, or both, that configure an arrangement of one or more processors (e.g., among the one or more processors of the machine) to perform the operations described herein for that component. Accordingly, different components of the comparative modeling system 150 may include and configure different arrangements of such processors or a single arrangement of such processors at different points in time. Moreover, any two or more components of the comparative modeling system 150 may be logically or physically combined into a single component, and the functions described herein for a single component may be subdivided among multiple components. Furthermore, according to various example embodiments, components described herein as being implemented within a single machine, database, or device may be distributed across multiple machines, databases, or devices.
In operation 310, the access component 210 receives a selection of a data set within a graphical user interface displayed on a display device of a client device. The data set includes a set of values associated with a set of identifiers. The access component 210 receives selection of the data set through the graphical user interface 400, as shown in
In some instances, prior to receiving the selection of the data set, the presentation component 250 generates and causes presentation of a graphical user interface 400. The graphical user interface 400 includes a set of selectable categorical input elements 410-430. In some embodiments, each of the selectable categorical elements 410-430 represent a distinct input, the combination of which enables the comparative modeling system 150 to generate and compare models for specified data sets. As shown in
As shown in
As shown, in some embodiments, a first data set element 414 is a text field configured to receive alphanumeric text. The access component 210, receiving text input into the first data set element 414, accesses a database including one or more data sets associated with the text received from the first data set element 414. The access component 210 may cause the presentation component 250 to display selectable representations (e.g., graphical interface elements) of the one or more data sets associated with the text received from the first data set element 414.
Upon receiving selection of the data set, the presentation component 250 generates a preview element 416. The preview element 416 is a selectable graphical interface element presented within the graphical user interface 400. In some instances, the preview element 416 may be generated proximate to the data set input 410. However, it should be understood that the presentation component 250 may cause presentation of the preview element 416 at any suitable location within the graphical user interface 400. In some embodiments, the presentation component 250 generates the preview element 416 as a pop-up window obscuring a portion of the graphical user interface 400. Selection of the preview element causes the presentation component 250 to generate and present at least a portion of the data set selected in operation 310. In some instances, the preview is a formatted representation of the portion of the data set. The formatted representation may be based on raw data included in a database as all or part of the set of data, processed data according to a previously generated model, storage of the data into a specified format, or any other suitable representation.
Returning to
The transform families may include one or more algorithms, processes, or operations to modify data within the selected data set. In some embodiments, the transform families modify the data to conform to a format, type, or configuration suitable for one or more models specified within the model family input 430. For example, as shown, the transform families may include a binarization transform, a drop column transform, and a vector assembler transform. The binarization transform may convert data within the selected data set to a binary representation. The drop column transform may remove a selected or predetermined column from data within the selected data set. Although specific transform families are described within the present disclosure, it should be understood that any suitable transform, process, algorithm, or set of operations may be included which is configured to modify data into a format suitable for modeling by one or more modeling operations or algorithms.
In some embodiments, selection of the transform scheme may be understood as featurization and be performed by one or more of the modeling component 230 and the iteration component 260. Featurization may be described as a process of converting data found within a set of data from a first form (e.g., raw data) to a second form (e.g., data able to be used by a model or vectorizer). The comparative modeling system 150 enables featurization of multiple different data sets. After featurization, the comparative modeling system 150 enables combination of the multiple different featurized data sets. The different featurized data sets may be combined with a label table. The final combined table may be processed using a vectorizer or remain in the featurized combined data table form and be provided to the modeling component 230 for generating models, as described in more detail below.
In some instances, a featurization process, technique, algorithm, or set of operations creates a numerical conversion of the data from the set of data. Featurization may process and convert the set of data for regression modeling using bigram analysis, singular value decomposition, cross validation, or any other suitable featurization method. In some embodiments, featurization may organize data without modifying the format of the data. In these cases, featurization may modify a data structure or set of data to be presented with respect to a specified featurized value or variable. The featurization process may also generate indicators or labels used to organize the data in the second form. Featurization of the set of data may introduce additional data in order to translate the set of data from the first form to the second form. In these embodiments, the additional data may incorporate discrete values representative of labels or non-numerical representations into the set of data. For example, if the set of data is provided in a data table incorporating textual information, such as a name, the additional data, included in the data table, may assign columns for each name and a value in each entry for each newly assigned column. Where the name specified in the column is associated with the entry, a first value may specify the association of the name and the entry (e.g., the name corresponds with the specified entry). Where the name specified in the column is not associated with the entry, a second value may indicate no association.
In some embodiments, the presentation component 250 generates and causes presentation of the graphical user interface 400, including the transform scheme input 420. As shown in

In some embodiments, the set of machine-learning algorithms include a plurality of machine-learning or model algorithms. The set of machine-learning algorithms may include K-Nearest Neighbor, Logistic Regression, Linear Regression, K-Means, and other suitable machine-learning or modeling algorithms. Although described with specified machine-learning or modeling algorithms, it should be understood that the set of machine-learning algorithms may include any suitable machine-learning or modeling algorithm. In some instances, the set of machine-learning algorithms may include a plurality of variations of a single machine-learning algorithm. For example, as shown in
The K-Nearest Neighbor algorithm may comprise an instance-based learning classification or non-generalizing learning. The K-Nearest Neighbor algorithm may store instances of training data without constructing a general internal model. In some instances, classification by the K-Nearest Neighbor algorithm may be computed from a majority vote (e.g., simple majority) of the nearest neighbors of each point. A query point may be assigned a data class that has the most representatives within the nearest neighbors of the query point. Although described with an example embodiment, it should be understood that the K-Nearest Neighbor algorithm may be implemented in any suitable manner, such as a K-Nearest Neighbor regression algorithm or a K-Nearest Neighbor outlier algorithm.
The K-Means algorithm may comprise operations or processes to cluster data by testing or trying separate samples, within the set of data, in n groups of equal variance. The K-Means algorithm may minimize (e.g., theoretically or effectively minimize) a criterion known as inertia or within-cluster sum-of-squares. The K-Means algorithm may include specification of a number of clusters. In some embodiments, the number of clusters is specified by the user upon or after selection of the K-Means algorithm. The K-Means algorithm may scale to large numbers of samples and be used across a large range of application areas and data fields within the set of data.
The logistic regression algorithm may address binary classification problems. The logistic regression algorithm may output a binary logistic regression model. Given a new or additional data point from the selected set of data, the logistic regression model may make predictions by applying a logistic function. Although described with respect to an embodiment of a logistic regression algorithm, it should be understood that the logistic regression algorithm used by the comparative modeling system 150 may be a multinomial logistic regression, an ordered logistic regression, a mixed logit, a Bayesian logistic regression, or any other suitable logistic regression algorithm or model. As shown in
The linear regression algorithm may comprise Ordinary Least Squares Linear Regression, Linear Least Squares, simple linear regression, multivariate linear regression, or any other suitable linear regression algorithm. In some instances, selection of the linear regression algorithm within the graphical user interface 400 may cause the presentation component 250 to generate and cause presentation of a set of distinct linear regression algorithms to specify the type of linear regression being performed on the selected set of data using the selected transform, described above. The presentation component 250 may generate the set of distinct linear regression algorithms by retrieving identifiers of each linear regression algorithm of the set of distinct linear regression algorithms from a database. The presentation component 250 may then identify a graphical representation for each linear regression algorithm within the database. The presentation component 250 causes presentation of the set of distinct linear regression algorithms by rendering or inserting the graphical representations of each linear regression algorithm in the graphical user interface 400. For example, the presentation component 250 may render a pop up window with the graphical representations of the linear regression algorithms as selectable interface elements enabling selection of a linear regression algorithm upon a user interaction with a corresponding selectable interface element. The presentation component 250 may also render the graphical representations within the graphical user interface 400 such as within a drop down menu, within a newly generated tab or set of interface elements within the graphical user interface 400, or in any other suitable manner.
The presentation component 250 generates and causes presentation of the graphical user interface 400, including the model family input 430. As shown in

As shown in
The second parameter elements 714 and 724 are selectable elements configured to enable dual or primal formulation. Dual formulation may be implemented for L2 penalties with a libliner solver. In some instances, where samples of the data set are greater in number than the features, enabling dual formulation may be preferred or set as default. Although the first parameter elements 712 and 722 and the second parameter elements 714 and 724 are described using an example embodiment, it should be understood that each model, model family, or machine-learning algorithm may include one or more parameters which are selectable by the user to assist in tailoring selected models. In some instances, selecting, indicating, hovering, or other interface actions indicating interest in a parameter element causes the presentation component 250 to cause display of additional information relating to the parameter element of interest and use cases for the parameter element of interest.
Referring again to
In operation 360, the modeling component 230 generates a plurality of second models using the second machine-learning algorithm. In some example embodiments, operation 360 is performed in response to selection of a second modeling element configured to initiate modeling of the selected set of data, transformed according to the selected transform scheme and using the second machine-learning algorithm. In some instances, the first modeling element and the second modeling element may be a single combined modeling element causing operations 350 and 360 to be performed upon selection. In some embodiments, the first modeling element and the second modeling element may be separate modeling elements corresponding to a single machine-learning algorithm.
In operation 370, the comparison component 240 determines one or more comparison metric values for each of the plurality of first models and the plurality of second models. In some embodiments, the plurality of first models and the plurality of second models output data in specified formats. Each output format may be associated with a specified presentation format. The presentation formats may be suggested, recommended, or otherwise suitable presentation styles or parameters for viewing the model output. The comparison component 240 may determine the one or more comparison metric values as a function of outputs or modeled values of the first machine-learning algorithm and the second machine-learning algorithm. In some embodiments, the comparison component 240 determines a comparison metric value as an error rate, a binarization threshold variation (e.g., a selected stepwise change in a binarization threshold), an accuracy value, or other suitable model output, model parameters, model variables, or combinations thereof. In some embodiments, the comparison component 240 determines the comparison metric values automatically in response to selection of the first machine-learning algorithm and the second machine-learning algorithm. In some instances, the comparison component 240 determines the comparison metric values based on one or more selections within the graphical user interface 400. For example, the comparison component 240, upon initiation of modeling, may identify a selection of the first machine-learning algorithm and a selection of the second machine-learning algorithm. The comparison component 240 may then identify one or more parameter selections from among the selections of the first and second machine-learning algorithms. The comparison component 240 may then determine, from among the selected parameters, the one or more comparison metric values.
In operation 380, the presentation component 250 causes presentation of the comparison metric values for the plurality of first models and the plurality of second models. The presentation component 250 may cause presentation of a set of results of the models in the graphical user interface 400. In some embodiments, the set of results comprise the comparison metric values plotted against one another, against a static value, or against another variable value. As shown in
Interaction (e.g., clicking, hovering, selecting, tapping, touching) with a result representation may cause the presentation component 250 to generate a detail element 840. The detail element 840 may be comprise information about the specified result. For example, the detail element 840 may include a model indicator containing information detailing a model represented by the result, a parameter indicator detailing information describing one or more parameter selections for a selected machine-learning algorithm, and any other suitable information. In some instances, additional suitable information may describe one or more of the model, the data set, the transform scheme, the machine-learning algorithm, or the comparison metric value.
In some embodiments, the result depiction 800 may include a modification element 850. As will be explained in more detail below, the modification element 850 may be a selectable interface element. Selection of the modification element 850 may cause the presentation component 250 to cause presentation of a modification list. The modification list may comprise one or more modification schemes enabling alteration of the result depiction. Selection of a modification scheme may alter the result depiction 800 based on one or more comparison metric values identified by the comparison component 240. For example, selection of a modification element on or proximate to an x-axis allows configuration or manipulation of the x-axis, the information represented by the x-axis, or the values associated therewith. Selection of a modification element on or proximate to the y-axis allows configuration or manipulation of the y-axis. In these embodiments, the modification elements allow use of different graph types and different inputs into the graphs. In some embodiments, selection of a modification element, such as modification element 852, allows configuration of the graph type, which may also change the input configurations available.

In some instances, selection (e.g., clicking or tapping) of a summary indicator causes the presentation component 250 to generate and cause presentation of a result detail representation 900, as shown in
As shown in
In some embodiment, the weight element 1040 corresponds to a dynamic weight function used in generating prediction models. The weight function may be uniform such that all points in each neighborhood are weighted equally. The weight function may provide distance-based weights. In these instances, weights are generated using or based on an inverse of a distance between points in a specified neighborhood. Closer neighbors within a neighborhood may have a greater weight (e.g., influence) on immediate neighbors than neighbors which are more distant. The weight function may also be user defined. The user defined weight function may receive values from the user as an array of distances and return an array containing calculated weights. The algorithm element 1050 corresponds to one or more algorithms used to calculate nearest neighbors. The algorithm element 1050 may enable selections of differing predetermined or user supplied algorithms. In some instances, the algorithm element 1050 includes selection for a BallTree algorithm, a KDTree algorithm, a brute force algorithm, or an automated selection. The automated selection causes the modeling component 230 to determine an appropriate algorithm from options provided within the algorithm element 1050 based on one or more values passed through selections of the parameter elements. The power element 1060 may correspond to a Minkowski Metric, having elements defined by a matrix. Values entered for the power element 1060 may be equivalent to known distances such as the Manhattan distance, the Euclidean distance, or an arbitrary Minkowski distance.
In some embodiments, the neighbor element 1030 includes a neighbor adjustment element 1070. Selection of the neighbor adjustment element 1070 causes the presentation component 250 to generate and cause presentation of a set of neighbor parameter values for the neighbor element 1030, as shown in

In operation 1510, the iteration component 260 determines a first iteration order for the two or more parameters within the first machine-learning algorithm and a second iteration order for the two or more parameters within the second machine-learning algorithm. For example, the iteration component 260 may determine that a model is to contain between one and five layers and up to ten nodes per layer. In some embodiments, operation 1510 is performed in response to receiving selection of and values for parameters represented by the first parameter elements 712 and 722 and the second parameter elements 714 and 724. Although described with respect to an example embodiment, it should be understood that the iteration component 260 may determine the first iteration order and the second iteration order by selection of any suitable parameters presented by the presentation component 250. In some instances, the first iteration order and the second iteration order may be determined from a set of upper and lower bounds and a step value indicating a number, frequency, or order of iterations occurring between the upper and lower bounds for each of the first machine-learning algorithm and the second machine-learning algorithm.
In operation 1520, the iteration component 260 determines a first iteration value for each parameter of the two or more parameters within the first machine-learning algorithm and a second iteration value for each parameter of the two or more parameters within the second machine-learning algorithm. In some embodiments, the iteration component 260 determines the first iteration value by identifying a parameter value for the first machine-learning algorithm, which represents a lower bound. For example, the lower bound may be a number of neighbors, a penalty, or any other suitable lower bound. The iteration component 260 may determine the second iteration value for the second machine-learning algorithm similarly to or the same as the determination of the first iteration value.
In operation 1530, the modeling component 230 iteratively models the set of values of the data set by processing the set of values according to the first machine-learning algorithm according to the first iteration order and the first iteration value. In some embodiments, operation 1530 is performed as part of or a sub-operation of operation 350, described above with respect to
In some embodiments, operation 1530 includes operation 1532. In operation 1532, the modeling component 230 generates a first set of models for the set of values. Each model of the first set of models corresponds to a different first iteration value of each parameter of the two or more parameters within the first machine-learning algorithm. For example, where a selected machine-learning algorithm includes a first parameter and a second parameter, where the second parameter compliments the first parameter, the modeling component 230 generates an iterative model for each step identified for the second parameter at each step identified for the first parameter. For example, where the first parameter includes ten steps and the second parameter includes five steps, the modeling component 230 may generate three iterative models from the steps of the second parameter for each step of the first parameter. In this example, the modeling component 230 generates fifty models, with each model corresponding to a single step of the second parameter with respect to a single step of the first parameter.
In operation 1540, the modeling component 230 iteratively models the set of values of the data set by processing the set of values according to the second machine-learning algorithm according to the second iteration order and the second iteration value. In some embodiments, operation 1540 is performed as part of or a sub-operation of operation 360, described above with respect to
In some embodiments, operation 1540 includes operation 1542. In operation 1542, the modeling component generates a second set of models for the set of values. Each model of the second set of models corresponds to a different second iteration value of each parameter of the two or more parameters within the second machine-learning algorithm. In some instances, operation 1542 is performed for the second machine-learning algorithm similarly to or the same as operation 1532, described above.
In operation 1610, the presentation component 250 generates a graphical user interface having a set of selectable graphical interface elements. The set of selectable graphical interface elements may include a first graphical interface element, a second graphical interface element, and a third graphical interface element. The first graphical interface element represents a set of data sets. The second graphical interface element represents a set of transform families. The third graphical interface element represents a set of model families. Each model family represents a machine-learning algorithm. An example of the graphical user interface, generated by the presentation component 250, is depicted in and described with respect to
Although described with respect to a single graphical interface element, in some embodiments, the first, second, and third graphical interface elements are generated as a first set, a second set, and a third set of graphical interface elements, respectively. In these example embodiments, the first set of graphical interface elements includes one or more graphical interface elements, each representing a discrete data set of the set of data sets. The second set of graphical interface elements includes one or more graphical interface elements, each representing a discrete transform family of the set of transform families. The third set of graphical interface elements includes one or more graphical interface elements, each graphical interface element representing a discrete model family of the set of model families.
In operation 1620, the presentation component 250 causes presentation of the graphical user interface prior to receiving selections of the data set, the transform scheme, and one or more machine-learning algorithms. Although described as receiving a single selection of the data set and the transform scheme, it should be understood that the comparative modeling system 150 may receive a plurality of selections for a plurality of data sets and a plurality of transform families.
In operation 1710, the modeling component 230 receives an additional modeling family. The modeling family may include a family identification and a set of code for a machine-learning algorithm. In these embodiments, the set of model families initially occurring within the comparative modeling system 150 may comprise a predetermined set of model families. The predetermined set of model families may be default machine-learning algorithms or machine-learning algorithms appended to a set of default machine-learning algorithms.
In operation 1720, the modeling component 230 incorporates the additional model family into the set of model families. The additional model family (e.g., one or more additional machine-learning algorithms) may be incorporated into the set of model families by the modeling component 230 inserting machine-readable coding for the additional model family into a database containing the set of model families. In some embodiments, the modeling component 230 modifies one or more data structures within the database, when adding the additional model family, to incorporate an identification for the additional model family for inclusion and presentation of a representation of the additional model family in a graphical user interface (e.g., the graphical user interface 400).
In operation 1730, the presentation component 250 generates a selectable graphical interface element for the additional model family within the third graphical interface element. The selectable graphical interface element may include an identification for the additional model family (e.g., a title of a machine-learning algorithm). In some instances, the identification for the additional model family is accessed from the data structure within the database. Upon accessing the identification within the data structure, the presentation component 250 may apply the identification to a previously generated interface element template. In some instances, the previously generated interface element template may be an interface element having a text box configured to receive the identification. Once the identification has been applied to the interface element template, the resulting selectable interface element may be stored within the data structure such that the selectable interface element is associated with one or more of the identification of the additional model family and the code for the machine-learning algorithm.
Certain embodiments are described herein as including logic or a number of components, modules, or mechanisms. Modules may constitute either software modules (e.g., code embodied on a machine-readable medium) or hardware modules. A “hardware module” is a tangible unit capable of performing certain operations and may be configured or arranged in a certain physical manner. In various example embodiments, one or more computer systems (e.g., a standalone computer system, a client computer system, or a server computer system) or one or more hardware modules of a computer system (e.g., a processor or a group of processors) may be configured by software (e.g., an application or application portion) as a hardware module that operates to perform certain operations as described herein.
In some embodiments, a hardware module may be implemented mechanically, electronically, or any suitable combination thereof. For example, a hardware module may include dedicated circuitry or logic that is permanently configured to perform certain operations. For example, a hardware module may be a special-purpose processor, such as a Field-Programmable Gate Array (FPGA) or an Application Specific Integrated Circuit (ASIC). A hardware module may also include programmable logic or circuitry that is temporarily configured by software to perform certain operations. For example, a hardware module may include software executed by a general-purpose processor or other programmable processor. Once configured by such software, hardware modules become specific machines (or specific components of a machine) uniquely tailored to perform the configured functions and are no longer general-purpose processors. It will be appreciated that the decision to implement a hardware module mechanically, in dedicated and permanently configured circuitry, or in temporarily configured circuitry (e.g., configured by software) may be driven by cost and time considerations.
Accordingly, the phrase “hardware module” should be understood to encompass a tangible entity, be that an entity that is physically constructed, permanently configured (e.g., hardwired), or temporarily configured (e.g., programmed) to operate in a certain manner or to perform certain operations described herein. As used herein, “hardware-implemented module” refers to a hardware module. Considering embodiments in which hardware modules are temporarily configured (e.g., programmed), each of the hardware modules need not be configured or instantiated at any one instance in time. For example, where a hardware module comprises a general-purpose processor configured by software to become a special-purpose processor, the general-purpose processor may be configured as respectively different special-purpose processors (e.g., comprising different hardware modules) at different times. Software accordingly configures a particular processor or processors, for example, to constitute a particular hardware module at one instance of time and to constitute a different hardware module at a different instance of time.
Hardware modules can provide information to, and receive information from, other hardware modules. Accordingly, the described hardware modules may be regarded as being communicatively coupled. Where multiple hardware modules exist contemporaneously, communications may be achieved through signal transmission (e.g., over appropriate circuits and buses) between or among two or more of the hardware modules. In embodiments in which multiple hardware modules are configured or instantiated at different times, communications between such hardware modules may be achieved, for example, through the storage and retrieval of information in memory structures to which the multiple hardware modules have access. For example, one hardware module may perform an operation and store the output of that operation in a memory device to which it is communicatively coupled. A further hardware module may then, at a later time, access the memory device to retrieve and process the stored output. Hardware modules may also initiate communications with input or output devices, and can operate on a resource (e.g., a collection of information).
The various operations of example methods described herein may be performed, at least partially, by one or more processors that are temporarily configured (e.g., by software) or permanently configured to perform the relevant operations. Whether temporarily or permanently configured, such processors may constitute processor-implemented modules that operate to perform one or more operations or functions described herein. As used herein, “processor-implemented module” refers to a hardware module implemented using one or more processors.
Similarly, the methods described herein may be at least partially processor-implemented, with a particular processor or processors being an example of hardware. For example, at least some of the operations of a method may be performed by one or more processors or processor-implemented modules. Moreover, the one or more processors may also operate to support performance of the relevant operations in a “cloud computing” environment or as a “software as a service” (SaaS). For example, at least some of the operations may be performed by a group of computers (as examples of machines including processors), with these operations being accessible via a network (e.g., the Internet) and via one or more appropriate interfaces (e.g., an API).
The performance of certain of the operations may be distributed among the processors, not only residing within a single machine, but deployed across a number of machines. In some example embodiments, the processors or processor-implemented modules may be located in a single geographic location (e.g., within a home environment, an office environment, or a server farm). In other example embodiments, the processors or processor-implemented modules may be distributed across a number of geographic locations.
The components, methods, applications and so forth described in conjunction with
Software architectures are used in conjunction with hardware architectures to create devices and machines tailored to particular purposes. For example, a particular hardware architecture coupled with a particular software architecture will create a mobile device, such as a mobile phone, tablet device, or so forth. A slightly different hardware and software architecture may yield a smart device for use in the “internet of things.” While yet another combination produces a server computer for use within a cloud computing architecture. Not all combinations of such software and hardware architectures are presented here, as those of skill in the art can readily understand how to implement the embodiments of the present disclosure in different contexts from the disclosure contained herein.
In the example architecture of
The operating system 1814 may manage hardware resources and provide common services. The operating system 1814 may include, for example, a kernel 1828, services 1830, and drivers 1832. The kernel 1828 may act as an abstraction layer between the hardware and the other software layers. For example, the kernel 1828 may be responsible for memory management, processor management (e.g., scheduling), component management, networking, security settings, and so on. The services 1830 may provide other common services for the other software layers. The drivers 1832 may be responsible for controlling or interfacing with the underlying hardware. For instance, the drivers 1832 may include display drivers, camera drivers, Bluetooth® drivers, flash memory drivers, serial communication drivers (e.g., Universal Serial Bus (USB) drivers), WiFi® drivers, audio drivers, power management drivers, and so forth depending on the hardware configuration.
The libraries 1816 may provide a common infrastructure that may be utilized by the applications 1820 and/or other components and/or layers. The libraries 1816 typically provide functionality that allows other software modules to perform tasks in an easier fashion than to interface directly with the underlying operating system 1814 functionality (e.g., kernel 1828, services 1830 and/or drivers 1832). The libraries 1816 may include system 1834 libraries (e.g., C standard library) that may provide functions such as memory allocation functions, string manipulation functions, mathematic functions, and the like. In addition, the libraries 1816 may include API libraries 1836 such as media libraries (e.g., libraries to support presentation and manipulation of various media format such as MPREG4, H.264, MP3, AAC, AMR, JPG, PNG), graphics libraries (e.g., an OpenGL framework that may be used to render 2D and 3D in a graphic content on a display), database libraries (e.g., SQLite that may provide various relational database functions), web libraries (e.g., WebKit that may provide web browsing functionality), and the like. The libraries 1816 may also include a wide variety of other libraries 1838 to provide many other APIs to the applications 1820 and other software components/modules.
The frameworks 1818 (also sometimes referred to as middleware) may provide a higher-level common infrastructure that may be utilized by the applications 1820 and/or other software components/modules. For example, the frameworks 1818 may provide various graphic user interface (GUI) functions, high-level resource management, high-level location services, and so forth. The frameworks 1818 may provide a broad spectrum of other APIs that may be utilized by the applications 1820 and/or other software components/modules, some of which may be specific to a particular operating system or platform.
The applications 1820 includes built-in applications 1840 and/or third party applications 1842. Examples of representative built-in applications 1840 may include, but are not limited to, a contacts application, a browser application, a book reader application, a location application, a media application, a messaging application, and/or a game application. Third party applications 1842 may include any of the built in applications as well as a broad assortment of other applications. In a specific example, the third party application 1842 (e.g., an application developed using the Android™ or iOS™ software development kit (SDK) by an entity other than the vendor of the particular platform) may be mobile software running on a mobile operating system such as iOS™, Android™, Windows® Phone, or other mobile operating systems. In this example, the third party application 1842 may invoke the API calls 1824 provided by the mobile operating system such as operating system 1814 to facilitate functionality described herein.
The applications 1820 may utilize built in operating system functions (e.g., kernel 1828, services 1830 and/or drivers 1832), libraries (e.g., system 1834, APIs 1836, and other libraries 1838), frameworks/middleware 1818 to create user interfaces to interact with users of the system. Alternatively, or additionally, in some systems interactions with a user may occur through a presentation layer, such as presentation layer 1844. In these systems, the application/module “logic” can be separated from the aspects of the application/module that interact with a user.
Some software architectures utilize virtual machines. In the example of
The machine 1900 may include processors 1910, memory 1930, and I/O components 1950, which may be configured to communicate with each other such as via a bus 1902. In an example embodiment, the processors 1910 (e.g., a Central Processing Unit (CPU), a Reduced Instruction Set Computing (RISC) processor, a Complex Instruction Set Computing (CISC) processor, a Graphics Processing Unit (GPU), a Digital Signal Processor (DSP), an Application Specific Integrated Circuit (ASIC), a Radio-Frequency Integrated Circuit (RFIC), another processor, or any suitable combination thereof) may include, for example, processor 1912 and processor 1914 that may execute instructions 1916. The term “processor” is intended to include multi-core processor that may comprise two or more independent processors (sometimes referred to as “cores”) that may execute instructions contemporaneously. Although
The memory/storage 1930 may include a memory 1932 (e.g., a processor-readable storage device), such as a main memory, or other memory storage, and a storage unit 1936, both accessible to the processors 1910 such as via the bus 1902. The storage unit 1936 and memory 1932 store the instructions 1916 embodying any one or more of the methodologies or functions described herein. The instructions 1916 may also reside, completely or partially, within the memory 1932, within the storage unit 1936, within at least one of the processors 1910 (e.g., within the processor's cache memory), or any suitable combination thereof, during execution thereof by the machine 1900. Accordingly, the memory 1932, the storage unit 1936, and the memory of processors 1910 are examples of machine-readable media.
As used herein, “machine-readable medium” means a device able to store instructions and data temporarily or permanently and may include, but is not be limited to, random-access memory (RAM), read-only memory (ROM), buffer memory, flash memory, optical media, magnetic media, cache memory, other types of storage (e.g., Erasable Programmable Read-Only Memory (EEPROM)) and/or any suitable combination thereof. The term “machine-readable medium” should be taken to include a single medium or multiple media (e.g., a centralized or distributed database, or associated caches and servers) able to store instructions 1916. The term “machine-readable medium” shall also be taken to include any medium, or combination of multiple media, that is capable of storing instructions (e.g., instructions 1916) for execution by a machine (e.g., machine 1900), such that the instructions, when executed by one or more processors of the machine 1900 (e.g., processors 1910), cause the machine 1900 to perform any one or more of the methodologies described herein. Accordingly, a “machine-readable medium” refers to a single storage apparatus or device, as well as “cloud-based” storage systems or storage networks that include multiple storage apparatus or devices. The term “machine-readable medium” excludes signals per se.
The I/O components 1950 may include a wide variety of components to receive input, provide output, produce output, transmit information, exchange information, capture measurements, and so on. The specific I/O components 1950 that are included in a particular machine will depend on the type of machine. For example, portable machines such as mobile phones will likely include a touch input device or other such input mechanisms, while a headless server machine will likely not include such a touch input device. It will be appreciated that the I/O components 1950 may include many other components that are not shown in
In further example embodiments, the I/O components 1950 may include biometric components 1956, motion components 1958, environmental components 1960, or position components 1962 among a wide array of other components. For example, the biometric components 1956 may include components to detect expressions (e.g., hand expressions, facial expressions, vocal expressions, body gestures, or eye tracking), measure biosignals (e.g., blood pressure, heart rate, body temperature, perspiration, or brain waves), identify a person (e.g., voice identification, retinal identification, facial identification, fingerprint identification, or electroencephalogram based identification), and the like. The motion components 1958 may include acceleration sensor components (e.g., accelerometer), gravitation sensor components, rotation sensor components (e.g., gyroscope), and so forth. The environmental components 1960 may include, for example, illumination sensor components (e.g., photometer), temperature sensor components (e.g., one or more thermometer that detect ambient temperature), humidity sensor components, pressure sensor components (e.g., barometer), acoustic sensor components (e.g., one or more microphones that detect background noise), proximity sensor components (e.g., infrared sensors that detect nearby objects), gas sensors (e.g., gas detection sensors to detection concentrations of hazardous gases for safety or to measure pollutants in the atmosphere), or other components that may provide indications, measurements, or signals corresponding to a surrounding physical environment. The position components 1962 may include location sensor components (e.g., a Global Position System (GPS) receiver component), altitude sensor components (e.g., altimeters or barometers that detect air pressure from which altitude may be derived), orientation sensor components (e.g., magnetometers), and the like.
Communication may be implemented using a wide variety of technologies. The I/O components 1950 may include communication components 1964 operable to couple the machine 1900 to a network 1980 or devices 1970 via coupling 1982 and coupling 1972, respectively. For example, the communication components 1964 may include a network interface component or other suitable device to interface with the network 1980. In further examples, communication components 1964 may include wired communication components, wireless communication components, cellular communication components, Near Field Communication (NFC) components, Bluetooth® components (e.g., Bluetooth® Low Energy), WiFi® components, and other communication components to provide communication via other modalities. The devices 1970 may be another machine or any of a wide variety of peripheral devices (e.g., a peripheral device coupled via a Universal Serial Bus (USB)).
Moreover, the communication components 1964 may detect identifiers or include components operable to detect identifiers. For example, the communication components 1964 may include Radio Frequency Identification (RFID) tag reader components, NFC smart tag detection components, optical reader components (e.g., an optical sensor to detect one-dimensional bar codes such as Universal Product Code (UPC) bar code, multi-dimensional bar codes such as Quick Response (QR) code, Aztec code, Data Matrix, Dataglyph, MaxiCode, PDF417, Ultra Code, UCC RSS-2D bar code, and other optical codes), or acoustic detection components (e.g., microphones to identify tagged audio signals). In addition, a variety of information may be derived via the communication components 1964, such as, location via Internet Protocol (IP) geo-location, location via Wi-Fi® signal triangulation, location via detecting a NFC beacon signal that may indicate a particular location, and so forth.
In various example embodiments, one or more portions of the network 1980 may be an ad hoc network, an intranet, an extranet, a virtual private network (VPN), a local area network (LAN), a wireless LAN (WLAN), a wide area network (WAN), a wireless WAN (WWAN), a metropolitan area network (MAN), the Internet, a portion of the Internet, a portion of the Public Switched Telephone Network (PSTN), a plain old telephone service (POTS) network, a cellular telephone network, a wireless network, a Wi-Fi® network, another type of network, or a combination of two or more such networks. For example, the network 1980 or a portion of the network 1980 may include a wireless or cellular network and the coupling 1982 may be a Code Division Multiple Access (CDMA) connection, a Global System for Mobile communications (GSM) connection, or other type of cellular or wireless coupling. In this example, the coupling 1982 may implement any of a variety of types of data transfer technology, such as Single Carrier Radio Transmission Technology (1×RTT), Evolution-Data Optimized (EVDO) technology, General Packet Radio Service (GPRS) technology, Enhanced Data rates for GSM Evolution (EDGE) technology, third Generation Partnership Project (3GPP) including 3G, fourth generation wireless (4G) networks, Universal Mobile Telecommunications System (UMTS), High Speed Packet Access (HSPA), Worldwide Interoperability for Microwave Access (WiMAX), Long Term Evolution (LTE) standard, others defined by various standard setting organizations, other long range protocols, or other data transfer technology.
The instructions 1916 may be transmitted or received over the network 1980 using a transmission medium via a network interface device (e.g., a network interface component included in the communication components 1964) and utilizing any one of a number of well-known transfer protocols (e.g., hypertext transfer protocol (HTTP)). Similarly, the instructions 1916 may be transmitted or received using a transmission medium via the coupling 1972 (e.g., a peer-to-peer coupling) to devices 1970. The term “transmission medium” shall be taken to include any intangible medium that is capable of storing, encoding, or carrying instructions 1916 for execution by the machine 1900, and includes digital or analog communications signals or other intangible medium to facilitate communication of such software.
