The present invention relates in general to computing systems, and more particularly, to various embodiments for intelligent generation of image-like representations of ordered and heterogenous data to enable explainability of artificial intelligence results in a computing environment using a computing processor.
In today's society, consumers, business persons, educators, and others use various computing network systems with increasing frequency in a variety of settings. The advent of computers and networking technologies have made possible the increase in the quality of life while enhancing day-to-day activities. For example, processing devices, with the advent and further miniaturization of integrated circuits, have made it possible to be integrated into a wide variety of devices. As great strides and advances in technologies come to fruition, these technological advances can be then brought to bear in everyday life. For example, the vast amount of available data made possible by computing and networking technologies may then assist in improvements to improve the quality of life and future life choices and planning.
Various embodiments for intelligent interpretation of image processing results using machine learning in a computing environment by a processor, are provided. In one embodiment, by way of example only, a method for implementing intelligent generation of image-like representations of ordered and heterogenous data to enable explainability of artificial intelligence results in a computing environment, again by a processor, is provided. One or more data sets may be transformed into one or more pseudo-image representations to enable one or more image processing tasks for image processing. An interpretation of an image processing task result from applying the one or more image processing tasks on the one or more pseudo-image representations generated from one or more data sets.
In order that the advantages of the invention will be readily understood, a more particular description of the invention briefly described above will be rendered by reference to specific embodiments that are illustrated in the appended drawings. Understanding that these drawings depict only typical embodiments of the invention and are not therefore to be considered to be limiting of its scope, the invention will be described and explained with additional specificity and detail through the use of the accompanying drawings, in which:
As the amount of electronic information continues to increase, the demand for sophisticated information access systems also grows. Big Data is a collection of tools, techniques, and operations used for data sets that becomes so voluminous and complex that traditional data processing applications are inadequate to store, query, analyze or process the data sets using current database management and data warehousing tools or traditional data processing applications. For example, image analysis is an important type of big data analytics. Such analysis may include medical image analysis (e.g., anatomy segmentation, computer aided diagnosis), general three-dimensional (“3D”) image analysis (e.g., video analysis) and two-dimensional (“2D”) image analysis (e.g., scene reconstruction, event detection, object recognition). Imagine analysis may need to involve machine learning or deep learning operations to produce some image task result and an associated explanation that is human interpretable and refers to an input dataset. Thus, a need exists for artificial intelligence (“AI”) systems to employ machine learning and deep learning operations working on image data provide an explanation/interpretation of the image data tasks results.
Accordingly, various embodiments described herein provide a data preparation step to: (a) transform complex heterogeneous data into image-like representations that enables the use of machine learning or deep learning techniques for image processing, and/or (b) build an interpretable explanation of the image processing results obtained by such image-oriented machine learning or deep learning techniques. The explanations may be used as input data (or information derived from them) as evidence.
In one aspect, the present invention provides for implementing intelligent generation of image-like representations of ordered and heterogenous data to enable explainability of artificial intelligence results in a computing environment, again by a processor, is provided. One or more data sets may be transformed into one or more pseudo-image representations to enable one or more image processing tasks for image processing. An interpretation of an image processing task result from applying the one or more image processing tasks on the one or more pseudo-image representations generated from one or more data sets.
Moreover, in dealing with a collection of complex datasets, each dataset may be an ordered collection of heterogeneous data. Thus, machine learning or deep learning operations may be employed to process one or more images to accomplish a task on one or more datasets while building, generating, and/or creating an interpretable explanation of the result of the image processing task. For example, an image processing task may include, but not limited to, classifying an input dataset such as, for example, Di. Another image processing task may compare two datasets Di and Dj according to a selected metric. The present invention may manage and process the collection of complex datasets (e.g., heterogeneous datasets) in the sense that the data in each set dataset Di may be ordered according to a defined/selected criteria such as, for example, a time criteria. The present invention may manage and process the collection of complex datasets (e.g., heterogeneous datasets) such that each data point in every dataset Di belongs to a single class (e.g., one class). In one aspect, the number of classes may be either predefined or learned. Additionally, the classes may be domain specific such as, for example, in the medical domain a class may be “medications”, which may include all data related to some medication for the patient. In the “social media” domain, for example, a class may be “location”, which may include all data related to geographical places where a user have been/traveled, etc.
It should be noted as used herein, “intelligent” (or “intelligence”) may refer to a mental action or process of acquiring knowledge and understanding through thought, experience, and one or more senses using machine learning (which may include using sensor based devices or other computing systems that include audio or video devices). “Intelligence” may also refer to identifying patterns of behavior, leading to a “learning” of one or more events, operations, or processes. The term “intelligent” or “intelligence” may refer to an artificial intelligent/machine learning system. The intelligent system may be a specialized computer system, or set of computer systems, configured with hardware and/or software logic (in combination with hardware logic upon which the software executes) to emulate human cognitive functions. These intelligent systems apply human-like characteristics to convey and manipulate ideas which, when combined with the inherent strengths of digital computing, can solve problems with a high degree of accuracy (e.g., within a defined percentage range or above an accuracy threshold) and resilience on a large scale. An intelligent system may perform one or more computer-implemented cognitive operations that approximate a human thought process while enabling a user or a computing system to interact in a more natural manner. An intelligent system may comprise artificial intelligence logic, such as natural language processing (NLP) based logic, for example, and machine learning logic, which may be provided as specialized hardware, software executed on hardware, or any combination of specialized hardware and software executed on hardware. The logic of the intelligent system may implement the cognitive operation(s), examples of which include, but are not limited to, question answering, identification of related concepts within different portions of content in a corpus, and intelligent search algorithms, such as Internet web page searches.
In general, such intelligent systems are able to perform the following functions: 1) Navigate the complexities of human language and understanding; 2) Ingest and process vast amounts of structured and unstructured data; 3) Generate and evaluate hypotheses; 4) Weigh and evaluate responses that are based only on relevant evidence; 5) Provide situation-specific advice, insights, estimations, determinations, evaluations, calculations, and guidance; 6) Improve knowledge and learn with each iteration and interaction through machine learning processes; 7) Enable decision making at the point of impact (contextual guidance); 8) Scale in proportion to a task, process, or operation; 9) Extend and magnify human expertise and cognition; 10) Identify resonating, human-like attributes and traits from natural language; 11) Deduce various language specific or agnostic attributes from natural language; 12) Memorize and recall relevant data points (images, text, voice) (e.g., a high degree of relevant recollection from data points (images, text, voice) (memorization and recall)); and/or 13) Predict and sense with situational awareness operations that mimic human cognition based on experiences.
It should be noted that one or more calculations may be performed using various mathematical operations or functions that may involve one or more mathematical operations (e.g., solving differential equations or partial differential equations analytically or computationally, using addition, subtraction, division, multiplication, standard deviations, means, averages, percentages, statistical modeling using statistical distributions, by finding minimums, maximums or similar thresholds for combined variables, etc.).
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, embodiments of the present invention 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.

As one of ordinary skill in the art will appreciate, the depiction of the various functional units in the intelligent generation of image-like representations of ordered and heterogenous data service 402 is for purposes of illustration, as the functional units may be located within the intelligent generation of image-like representations of ordered and heterogenous data service 402 or elsewhere within and/or between distributed computing components.
In one aspect, the computer system/server 12 and/or the intelligent generation of image-like representations of ordered and heterogenous data service 402 may provide virtualized computing services (i.e., virtualized computing, virtualized storage, virtualized networking, etc.). More specifically, the intelligent generation of image-like representations of ordered and heterogenous data service 402 may provide, and/or be included in, a virtualized computing, virtualized storage, virtualized networking and other virtualized services that are executing on a hardware substrate.
The intelligent generation of image-like representations of ordered and heterogenous data service 402 may also include an image-like representation generation component 420, which may transform one or more data sets into one or more pseudo-image representations to enable one or more image processing tasks for image processing and to provide an interpretation of an image processing task result from applying the one or more image processing tasks on the one or more pseudo-image representations generated from one or more data sets.

The result 430 of the machine/deep learning task (“T”) 412 may be mapped to one or more areas of the image-like representation (“I”), where the mapping function is M(R, I)=A (where “A” is area and the “A” is part of I). An explanation function 440 may be applied to generate an interpretable explanation 432 (e.g., G(D, A, R)=E), where E is a human-interpretable explanation of R. That is, an interpretable explanation 432 (e.g., a human-interpretable explanation) of the result 430 may be built, created, and/or generated.
In one embodiment, by way of example only, the machine learning operations as used herein may include, for example, an instance of IBM® Watson® such as Watson® Analytics (IBM® and Watson® are trademarks of International Business Machines Corporation).

In one aspect, in the medical domain the term “pathway” may refer to the ordered collection of heterogeneous data. A pathway may include data describing one or more events and other information pertaining to a specific condition of the patient. For illustration purposes only, in this example, a short pathway may be a pathway with few/limited data points. Thus, in the example a set of classes may be 1) demographics (e.g., patient details, immunizations, allergies), 2) observations and images (e.g., results of blood tests and other observations), 3) conditions and health care plans (e.g., diagnose and care plans), and/or 4) medications (e.g., list of prescriptions), procedures (e.g., treatment list), and/or5) outcomes (e.g., readmission, survival, eradication of diseases, etc.).

From the values of the highlighted region 522 of the encoded 2D matrix 520, the present invention may return back to the original data points in the input data (e.g., this is possible based on the generation of the encoded 2D matrix 530 as described herein). The original data points may then be used to generate an understandable interpretation (e.g., a human understandable explanation) of the classification result (e.g., the CNN result 532). In one aspect, if the classes (rows) of the highlighted values (e.g., highlighted region 522) of the encoded 2D matrix 530 are human-interpretable, then the present invention may add this information to the explanation of the classification result (e.g., the CNN result 532).
It should be noted that the above medical/healthcare example above is used by way of example only. Another example of a dataset that may be used is a timeline of a user in a social media network. For example, the timeline may be a time-ordered collections of heterogeneous data points (e.g., “social posts” or communications submitted to the social network by the user). The data points may be classified in a set of classes such as, for example, location, sentiment of the text posted by the user, tags (either assigned by user, or computed by software), and the like. Various embodiments as described herein may be applied, for example to the following use cases. For example, a social media network wants to analyze a user timelines to identify fake/illegitimate accounts, and provide human-interpretable explanations of why an account may be fake/illegitimate. The social media network may recommend social media associates (e.g., “friends”) or products to user X and adds one or more motivation of why X may be interested. Thus, the present invention may apply to a variety of ordered and heterogeneous data sets such as, for example, even large datasets (e.g., big data) such as, for example, as illustrated in

In an additional aspect, coordinate may be determined/calculated using a function H (e.g., a hash (“H”) function) that takes the data points (P), and return a number. In one aspect, there may be multiple H functions (e.g., a family of H functions) that may be used such as, for example, one H function for each class of heterogenous data (“D”), and any two different H functions (e.g., Hi and Hj) having disjoint ranges. Every H function may have a domain equal to the points in the respective class of heterogenous data (“D”), and range equal to a finite set of the natural numbers. In one aspect, the range of an H function is smaller than its domain.

The present invention may be a system, a method, and/or a computer program product. The computer program product may include a computer readable storage medium (or media) having computer readable program instructions thereon for causing a processor to carry out aspects of the present invention.
The computer readable storage medium can be a tangible device that can retain and store instructions for use by an instruction execution device. The computer readable storage medium may be, for example, but is not limited to, an electronic storage device, a magnetic storage device, an optical storage device, an electromagnetic storage device, a semiconductor storage device, or any suitable combination of the foregoing. A non-exhaustive list of more specific examples of the computer readable storage medium includes the following: a portable computer diskette, a hard disk, a random access memory (RAM), a read-only memory (ROM), an erasable programmable read-only memory (EPROM or Flash memory), a static random access memory (SRAM), a portable compact disc read-only memory (CD-ROM), a digital versatile disk (DVD), a memory stick, a floppy disk, a mechanically encoded device such as punch-cards or raised structures in a groove having instructions recorded thereon, and any suitable combination of the foregoing. A computer readable storage medium, as used herein, is not to be construed as being transitory signals per se, such as radio waves or other freely propagating electromagnetic waves, electromagnetic waves propagating through a waveguide or other transmission media (e.g., light pulses passing through a fiber-optic cable), or electrical signals transmitted through a wire.
Computer readable program instructions described herein can be downloaded to respective computing/processing devices from a computer readable storage medium or to an external computer or external storage device via a network, for example, the Internet, a local area network, a wide area network and/or a wireless network. The network may comprise copper transmission cables, optical transmission fibers, wireless transmission, routers, firewalls, switches, gateway computers and/or edge servers. 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 instructions for carrying out operations of the present invention may be assembler instructions, instruction-set-architecture (ISA) instructions, machine instructions, machine dependent instructions, microcode, firmware instructions, state-setting data, 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 conventional 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 of the present invention.
Aspects of the present invention are described herein with reference to flowchart illustrations and/or block diagrams of methods, apparatus (systems), and computer program products according to embodiments of the invention. 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
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 program products according to various embodiments of the present invention. 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). In some alternative implementations, the functions noted in the block may occur out of the order noted in the figures. For example, two blocks shown in succession may, in fact, be executed 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.
