DETAILED DESCRIPTION

Detailed embodiments of the claimed structures and methods are disclosed herein; however, it can be understood that the disclosed embodiments are merely illustrative of the claimed structures and methods that may be embodied in various forms. Those structures and methods may, however, be embodied in many different forms and should not be construed as limited to the exemplary embodiments set forth herein. Rather, these exemplary embodiments are provided so that this disclosure will be thorough and complete and will fully convey the scope to those skilled in the art. In the description, details of well-known features and techniques may be omitted to avoid unnecessarily obscuring the presented embodiments.

Embodiments relate generally to the field of machine learning, and more particularly to training machine learning models. The following described exemplary embodiments provide a system, method and computer program to, among other things, train a machine learning model with training data which emphasizes a particular feature at the expense of allowing for slightly lower accuracy. These features may include, among other things, comprehensibility in understanding the outputs of the model or personalization of the model so the outputs are tailored to a given user. Therefore, some embodiments have the capacity to improve the field of computing by allowing for a framework to identify and profile interesting data groups that have a greatest positive impact for improving leaning model performance through emphasizing features of a machine learning model by using iterating through permutations of training data. This may be used to increase weights of records, which not only has positive impact for improving specified feature importance but keep stable accuracy. It may be appreciated that emphasizing the importance of the specified feature is not limited to any specified machine learning algorithm.

As previously described, machine learning involves using computer algorithms that can improve automatically through experience and by the use of data. Machine learning algorithms build a model based on sample data, known as training data, in order to make predictions or decisions without being explicitly programmed to do so. Machine learning is used in a wide variety of applications where it is difficult or unfeasible to develop conventional algorithms to perform the needed tasks. When training a machine learning model, the accuracy of the model is typically the highest priority. Thus, many methods and approaches have been developed in order to build models having the highest accuracy.

However, in some cases or areas of study, accuracy of the model may not be the most important factor. For example, features such as the ability to understand the outputs of the model or the ability to understand how the model generated its outputs may be a more important consideration that accuracy of the model. It may be advantageous, therefore, to introduce training data that allows the model to emphasize certain features other than accuracy while still remaining above a minimum threshold accuracy value.

Aspects are described herein with reference to flowchart illustrations and/or block diagrams of methods, apparatus (systems), and computer readable media according to the various embodiments. It will be understood that each block of the flowchart illustrations and/or block diagrams, and combinations of blocks in the flowchart illustrations and/or block diagrams, can be implemented by computer readable program instructions.

The following described exemplary embodiments provide a system, method, and computer program that trains machine learning models based on emphasizing a particular feature within the training data. Specifically, the system, method, and computer program may evaluate feature importance within permutations of the training data in order for expected features to be identified as important within the data. This may be done through hierarchical clustering of the data to identify which data has the most positive impact in order to improve the importance of the specified feature within the model.

Referring now to FIG. 1, a functional block diagram of a networked computer environment illustrating a machine learning training system 100 (hereinafter “system”) for training machine learning models based on emphasizing a given feature. It should be appreciated that FIG. 1 provides only an illustration of one implementation and does not imply any limitations with regard to the environments in which different embodiments may be implemented. Many modifications to the depicted environments may be made based on design and implementation requirements.

The system 100 may include a computer 102 and a server computer 114. The computer 102 may communicate with the server computer 114 via a communication network 110 (hereinafter “network”). The computer 102 may include a processor 104 and a software program 108 that is stored on a data storage device 106 and is enabled to interface with a user and communicate with the server computer 114. As will be discussed below with reference to FIG. 4 the computer 102 may include internal components 800A and external components 900A, respectively, and the server computer 114 may include internal components 800B and external components 900B, respectively. The computer 102 may be, for example, a mobile device, a telephone, a personal digital assistant, a netbook, a laptop computer, a tablet computer, a desktop computer, or any type of computing devices capable of running a program, accessing a network, and accessing a database.

The server computer 114 may also operate in a cloud computing service model, such as Software as a Service (SaaS), Platform as a Service (PaaS), or Infrastructure as a Service (IaaS), as discussed below with respect to FIGS. 5 and 6. The server computer 114 may also be located in a cloud computing deployment model, such as a private cloud, community cloud, public cloud, or hybrid cloud.

The server computer 114, which may be used for training machine learning models based on emphasizing a particular feature is enabled to run a Machine Learning Training Program 116 (hereinafter “program”) that may interact with a database 112. The Machine Learning Training Program is explained in more detail below with respect to FIG. 3. In one embodiment, the computer 102 may operate as an input device including a user interface while the program 116 may run primarily on server computer 114. In an alternative embodiment, the program 116 may run primarily on one or more computers 102 while the server computer 114 may be used for processing and storage of data used by the program 116. It should be noted that the program 116 may be a standalone program or may be integrated into a larger machine learning training program.

It should be noted, however, that processing for the program 116 may, in some instances be shared amongst the computers 102 and the server computers 114 in any ratio. In another embodiment, the program 116 may operate on more than one computer, server computer, or some combination of computers and server computers, for example, a plurality of computers 102 communicating across the network 110 with a single server computer 114. In another embodiment, for example, the program 116 may operate on a plurality of server computers 114 communicating across the network 110 with a plurality of client computers. Alternatively, the program may operate on a network server communicating across the network with a server and a plurality of client computers.

The network 110 may include wired connections, wireless connections, fiber optic connections, or some combination thereof. In general, the network 110 can be any combination of connections and protocols that will support communications between the computer 102 and the server computer 114. The network 110 may include various types of networks, such as, for example, a local area network (LAN), a wide area network (WAN) such as the Internet, a telecommunication network such as the Public Switched Telephone Network (PSTN), a wireless network, a public switched network, a satellite network, a cellular network (e.g., a fifth generation (5G) network, a long-term evolution (LTE) network, a third generation (3G) network, a code division multiple access (CDMA) network, etc.), a public land mobile network (PLMN), a metropolitan area network (MAN), a private network, an ad hoc network, an intranet, a fiber optic-based network, or the like, and/or a combination of these or other types of networks.

The number and arrangement of devices and networks shown in FIG. 1 are provided as an example. In practice, there may be additional devices and/or networks, fewer devices and/or networks, different devices and/or networks, or differently arranged devices and/or networks than those shown in FIG. 1. Furthermore, two or more devices shown in FIG. 1 may be implemented within a single device, or a single device shown in FIG. 1 may be implemented as multiple, distributed devices. Additionally, or alternatively, a set of devices (e.g., one or more devices) of system 100 may perform one or more functions described as being performed by another set of devices of system 100.

Referring now to FIG. 2, a machine learning training system 200 is depicted according to one or more embodiments. The machine learning training system 200 may include, among other things, a partition module 202, a clustering module 204, a permutation module 206, and a database 208. The partition module 202 may partition data in a database 208 into testing data 210 and training data 212. The database 208 may substantially correspond with the database 112, as depicted in FIG. 1. The clustering module 204 may apply a hierarchical clustering to the training data 212. Specifically, the clustering module 204 may create a structure for the training data 212, such as a tree having one or more branches with one or more levels.

The permutation module 206 may build a base machine learning model and compute permutations to identify which data from among the data training data 212 results in a given feature from among the training data 212 being emphasized. This may be done by calculating a permutation having a greatest importance value. The importance value may be pre-defined based on business or individual needs associated with the machine learning model. Additionally, for each permutation, the permutation module 206 may calculate an accuracy value in order to ensure that the machine learning model remains accurate despite emphasizing one or more other features of the model. The permutation module 206 may determine which smallest group or cluster of data from the data structure created by the clustering module 204 has the greatest impact on the identified feature's importance. For each cluster at a bottom level of the data structure, the importance of the feature is determined. The permutation module may choose a branch based on the smallest group having the greatest impact and add the branch to the training data 212. As the permutation module 206 moves up the branch toward the root, weight values associated with the branch may decrease since each level of the branch may include other data that may not have as positive an effect on emphasizing the feature.

The features of the model may include:

- Fidelity: the output of the model is truthful to the process of how the model makes prediction(s), regardless of the complexity.
- Completeness: the output of the model covers many model behaviors or generalizes to many model decisions.
- Stability: the output remains consistent for similar cases the user asks about. Certainty: the explanation reflects the confidence of the model for inquired cases, so the user knows when the model is uncertain.
- Compactness: the output of the model gives only necessary information and does not overwhelm.
- Comprehensibility: the output of the model is easy to understand
- Actionability: the output of the model helps the user determine follow-up actions to achieve a goal for the task
- Interactivity: the output of the model is interactive, so the user can ask follow-up questions.
- Translucence: the output of the model is transparent about its limitations, for examples the conditions for it to hold
- Coherence: the output of the model is consistent with the user's prior knowledge about the domain
- Novelty: the output of the model provides new or surprising information that the user otherwise would not expect
- Personalization: the output of the model is tailored to the user's needs and preferences (e.g. level of details, communication styles, language, etc.)

The permutation module 206 may then build a new machine learning model with the training data 212 and the testing data 210. This process may iteratively continue until the specified feature's importance reaches an expected value or the accuracy of the model falls below the threshold. Alternatively, if a maximum number of iterations are performed without the feature reaching the expected importance value or the accuracy falling too low, the permutation module 206 may determine that such a model cannot be built. For example, for each cluster i in the data from the database 208, the cluster data may be added to the training data 212. The permutation module 206 may build a model and calculate permutation importance and accuracy with the testing data 210. The permutation module may check a specified feature's importance value. If the accuracy falls below a threshold value, the permutation module 206 may determine that the accuracy has become too low and may stop iteration due to failure to build a target model. Otherwise, if the permutation module 206 may continue while the feature importance may increase and reach an expected value.

Referring now to FIG. 3, an operational flowchart illustrating the steps of a method 300 carried out by a program that trains machine learning models is depicted. The method 300 may be discussed with the aid of the exemplary embodiments of FIG. 2.

At 302, the method 300 may include identifying a feature associated with training data derived from a dataset. The features may include, among other things, fidelity, completeness, stability, certainty, compactness, comprehensibility, actionability, interactivity, translucence, coherence, novelty, and personalization associated with the model. In operation, the partition module 202 may retrieve data from a database 208 and may separate the data into testing data 210 and training data 212. The clustering module 204 may identify one or more features to be emphasized within a model associated with the data.

At 304, the method 300 may include generating a machine learning model based on the training data. The machine learning model may be generated such that one of the features is deemed to be important. In operation, the clustering module 204 may generate a machine learning model based on the training data 212.

At 306, the method 300 may include selecting at least a portion of the training data associated with maximizing an importance value associated with the identified feature. The importance value corresponds to a need associated with the machine learning model. The feature may be emphasized within the model so long as accuracy of the model does not fall below a given threshold value. In operation, the permutation module 206 may determine a subset of the data maximizes a selected feature and may add the data to the training data 212.

At 308, the method 300 may include assigning one or more weight values to the selected portion of the training data. The weight values may be used to emphasize the importance of a feature within the data without sacrificing too much accuracy. In operation, the permutation module 206 may assign weight values to portions of training data 212 based on those portions having a greatest positive effect in emphasizing the desired feature of the machine learning model.

At 310, the method 300 may include updating the machine learning model based on the assigned weight values. The updated model may use training data with adjusted weight values to emphasize a particular feature. In operation, the permutation module 206 may update the machine learning model based on the weight values added to the training data 212.

It is understood in advance that although this disclosure includes a detailed description on cloud computing, implementation of the teachings recited herein are not limited to a cloud computing environment. Rather, some embodiments are capable of being implemented in conjunction with any other type of computing environment now known or later developed.

Cloud computing is a model of service delivery for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g. networks, network bandwidth, servers, processing, memory, storage, applications, virtual machines, and services) that can be rapidly provisioned and released with minimal management effort or interaction with a provider of the service. This cloud model may include at least five characteristics, at least three service models, and at least four deployment models.

Characteristics are as follows:

- On-demand self-service: a cloud consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with the service's provider.
- Broad network access: capabilities are available over a network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, laptops, and PDAs).
- Resource pooling: the provider's computing resources are pooled to serve multiple consumers using a multi-tenant model, with different physical and virtual resources dynamically assigned and reassigned according to demand. There is a sense of location independence in that the consumer generally has no control or knowledge over the exact location of the provided resources but may be able to specify location at a higher level of abstraction (e.g., country, state, or datacenter).
- Rapid elasticity: capabilities can be rapidly and elastically provisioned, in some cases automatically, to quickly scale out and rapidly released to quickly scale in. To the consumer, the capabilities available for provisioning often appear to be unlimited and can be purchased in any quantity at any time.
- Measured service: cloud systems automatically control and optimize resource use by leveraging a metering capability at some level of abstraction appropriate to the type of service (e.g., storage, processing, bandwidth, and active user accounts). Resource usage can be monitored, controlled, and reported providing transparency for both the provider and consumer of the utilized service.

Service Models are as follows:

- Software as a Service (SaaS): the capability provided to the consumer is to use the provider's applications running on a cloud infrastructure. The applications are accessible from various client devices through a thin client interface such as a web browser (e.g., web-based e-mail). The consumer does not manage or control the underlying cloud infrastructure including network, servers, operating systems, storage, or even individual application capabilities, with the possible exception of limited user-specific application configuration settings.
- Platform as a Service (PaaS): the capability provided to the consumer is to deploy onto the cloud infrastructure consumer-created or acquired applications created using programming languages and tools supported by the provider. The consumer does not manage or control the underlying cloud infrastructure including networks, servers, operating systems, or storage, but has control over the deployed applications and possibly application hosting environment configurations.
- Infrastructure as a Service (IaaS): the capability provided to the consumer is to provision processing, storage, networks, and other fundamental computing resources where the consumer is able to deploy and run arbitrary software, which can include operating systems and applications. The consumer does not manage or control the underlying cloud infrastructure but has control over operating systems, storage, deployed applications, and possibly limited control of select networking components (e.g., host firewalls).

Deployment Models are as follows:

- Private cloud: the cloud infrastructure is operated solely for an organization. It may be managed by the organization or a third party and may exist on-premises or off-premises.
- Community cloud: the cloud infrastructure is shared by several organizations and supports a specific community that has shared concerns (e.g., mission, security requirements, policy, and compliance considerations). It may be managed by the organizations or a third party and may exist on-premises or off-premises.
- Public cloud: the cloud infrastructure is made available to the general public or a large industry group and is owned by an organization selling cloud services.
- Hybrid cloud: the cloud infrastructure is a composition of two or more clouds (private, community, or public) that remain unique entities but are bound together by standardized or proprietary technology that enables data and application portability (e.g., cloud bursting for load-balancing between clouds).

A cloud computing environment is service oriented with a focus on statelessness, low coupling, modularity, and semantic interoperability. At the heart of cloud computing is an infrastructure comprising a network of interconnected nodes.

Referring to FIG. 5, illustrative cloud computing environment 500 is depicted. As shown, cloud computing environment 500 comprises one or more cloud computing nodes 10 with which local computing devices used by cloud consumers, such as, for example, personal digital assistant (PDA) or cellular telephone 54A, desktop computer 54B, laptop computer 54C, and/or automobile computer system 54N may communicate. Cloud computing nodes 10 may communicate with one another. They may be grouped (not shown) physically or virtually, in one or more networks, such as Private, Community, Public, or Hybrid clouds as described hereinabove, or a combination thereof. This allows cloud computing environment 500 to offer infrastructure, platforms and/or software as services for which a cloud consumer does not need to maintain resources on a local computing device. It is understood that the types of computing devices 54A-N shown in FIG. 5 are intended to be illustrative only and that cloud computing nodes 10 and cloud computing environment 500 can communicate with any type of computerized device over any type of network and/or network addressable connection (e.g., using a web browser).

A network adapter card or network interface in each computing/processing device receives computer readable program instructions from the network and forwards the computer readable program instructions for storage in a computer readable storage medium within the respective computing/processing device.

Computer readable program code/instructions for carrying out operations may be assembler instructions, instruction-set-architecture (ISA) instructions, machine instructions, machine dependent instructions, microcode, firmware instructions, state-setting data, configuration data for integrated circuitry, or either source code or object code written in any combination of one or more programming languages, including an object oriented programming language such as Smalltalk, C++, or the like, and procedural programming languages, such as the “C” programming language or similar programming languages. The computer readable program instructions may execute entirely on the user's computer, partly on the user's computer, as a stand-alone software package, partly on the user's computer and partly on a remote computer or entirely on the remote computer or server. In the latter scenario, the remote computer may be connected to the user's computer through any type of network, including a local area network (LAN) or a wide area network (WAN), or the connection may be made to an external computer (for example, through the Internet using an Internet Service Provider). In some embodiments, electronic circuitry including, for example, programmable logic circuitry, field-programmable gate arrays (FPGA), or programmable logic arrays (PLA) may execute the computer readable program instructions by utilizing state information of the computer readable program instructions to personalize the electronic circuitry, in order to perform aspects or operations.

These computer readable program instructions may be provided to a processor of a general purpose computer, special purpose computer, or other programmable data processing apparatus to produce a machine, such that the instructions, which execute via the processor of the computer or other programmable data processing apparatus, create means for implementing the functions/acts specified in the flowchart and/or block diagram block or blocks. These computer readable program instructions may also be stored in a computer readable storage medium that can direct a computer, a programmable data processing apparatus, and/or other devices to function in a particular manner, such that the computer readable storage medium having instructions stored therein comprises an article of manufacture including instructions which implement aspects of the function/act specified in the flowchart and/or block diagram block or blocks.

The computer readable program instructions may also be loaded onto a computer, other programmable data processing apparatus, or other device to cause a series of operational steps to be performed on the computer, other programmable apparatus or other device to produce a computer implemented process, such that the instructions which execute on the computer, other programmable apparatus, or other device implement the functions/acts specified in the flowchart and/or block diagram block or blocks.

The flowchart and block diagrams in the Figures illustrate the architecture, functionality, and operation of possible implementations of systems, methods, and computer readable media according to various embodiments. In this regard, each block in the flowchart or block diagrams may represent a module, segment, or portion of instructions, which comprises one or more executable instructions for implementing the specified logical function(s). The method, computer system, and computer readable medium may include additional blocks, fewer blocks, different blocks, or differently arranged blocks than those depicted in the Figures. In some alternative implementations, the functions noted in the blocks may occur out of the order noted in the Figures. For example, two blocks shown in succession may, in fact, be executed concurrently or substantially concurrently, or the blocks may sometimes be executed in the reverse order, depending upon the functionality involved. It will also be noted that each block of the block diagrams and/or flowchart illustration, and combinations of blocks in the block diagrams and/or flowchart illustration, can be implemented by special purpose hardware-based systems that perform the specified functions or acts or carry out combinations of special purpose hardware and computer instructions.

It will be apparent that systems and/or methods, described herein, may be implemented in different forms of hardware, firmware, or a combination of hardware and software. The actual specialized control hardware or software code used to implement these systems and/or methods is not limiting of the implementations. Thus, the operation and behavior of the systems and/or methods were described herein without reference to specific software code—it being understood that software and hardware may be designed to implement the systems and/or methods based on the description herein.

No element, act, or instruction used herein should be construed as critical or essential unless explicitly described as such. Also, as used herein, the articles “a” and “an” are intended to include one or more items, and may be used interchangeably with “one or more.” Furthermore, as used herein, the term “set” is intended to include one or more items (e.g., related items, unrelated items, a combination of related and unrelated items, etc.), and may be used interchangeably with “one or more.” Where only one item is intended, the term “one” or similar language is used. Also, as used herein, the terms “has,” “have,” “having,” or the like are intended to be open-ended terms. Further, the phrase “based on” is intended to mean “based, at least in part, on” unless explicitly stated otherwise.

The descriptions of the various aspects and embodiments have been presented for purposes of illustration but are not intended to be exhaustive or limited to the embodiments disclosed. Even though combinations of features are recited in the claims and/or disclosed in the specification, these combinations are not intended to limit the disclosure of possible implementations. In fact, many of these features may be combined in ways not specifically recited in the claims and/or disclosed in the specification. Although each dependent claim listed below may directly depend on only one claim, the disclosure of possible implementations includes each dependent claim in combination with every other claim in the claim set. Many modifications and variations will be apparent to those of ordinary skill in the art without departing from the scope of the described embodiments. The terminology used herein was chosen to best explain the principles of the embodiments, the practical application or technical improvement over technologies found in the marketplace, or to enable others of ordinary skill in the art to understand the embodiments disclosed herein.
