New Avenues of Design of Distributed Intelligent Systems: A Framework of Granular Computing

Prof. Witold Pedrycz

Department of Electrical & Computer Engineering University of Alberta, Edmonton Canada and Systems Research Institute, Polish Academy of Sciences Warsaw, Poland

Information granules, and fuzzy sets, in particular, have established themselves as a conceptual and algorithmic vehicle aimed to realize a thorough analysis and design of intelligent systems. With the manifestation of various facets of information granularity and their ensuing formal representations, type-2 and interval-valued fuzzy sets have become more visible and practically relevant. In this talk, we pursue this general line of thought by introducing granular fuzzy sets - fuzzy sets whose grades of membership are, in general, information granules themselves.

We thoroughly discuss a number of key formalisms of representing information granules (sets, intervals, fuzzy sets, rough sets, shadowed sets, etc.), emphasize their role in the formation of explicitly expressed knowledge tidbits, and discuss ways of acquiring of information granules on a basis of available experimental evidence. Given the plethora of formal settings of information granules, there are several principles, which hold regardless of this diversity and lead to a unified and cohesive processing platform: (i) the principle of justifiable granularity, (ii) an optimal allocation of information granularity, and (iii) emergence of hierarchies of layers of information granules (forming higher order and higher type constructs).

In the sequel, an origin, motivation, and selected representative examples arising in granular rule-based system modeling, especially in the context of distributed data, are discussed. We highlight key motivating factors behind the emergence of type-2 and order-2 of information granules and reveal apparent linkages between type-n information granules and hierarchical architectures of constructed models.

The role of information granules is elaborated on with regard to general problems of data quality and imputation mechanisms where we demonstrate that the results of imputation are inherently information granules rather than plain numeric entities.

Fuzzy signatures, situational maps and fuzzy signature state machines

Prof. Laszlo T. Koczy

Széchenyi István University, Budapest University of Technology and Economics, Hungary

In many engineering and other applied problems there is a series of (vague) features which may be grouped into subsets with components related closer to each other, even to sub-subsets within these subsets. Such structures may be represented by either a tree graph, or an iteratively nested vector (with sub-vectors as components). Such constructions will be called Fuzzy Signatures.

Such Fuzzy Signatures (FS) are complex, hierarchically structured uncertain descriptors which should be suitable for manipulations even when their respective actual tree structures are not entirely identical. The presentation will give an introduction to the definitions and basic operations in connection with FS.

A very special extension of the idea of FS is given by the Fuzzy Situational Maps (FSM) where the sub-trees represent matrices of two or more dimensions with more or less fixed spatial structure. Zoom in and Zoom out operations combined with proper fuzzy aggregations help to increase or decrease the detail view of a given part of the area described by the FSM, and at the same time, allow partial complexity reduction by shrinking the information into higher hierarchical levels.

When the fuzzy values at the leaves of the trees are time/sequence dependent, state machines emerge. A complex hierarchical system of interconnected or interrelated fuzzy state machines can be represented by a Fuzzy Signature State Machine. Basic concepts will be also introduced.

A series of possible applications of FSM will be presented, such as the description of the condition and renovation procedure of residential buildings, warehouse layouts and inbounding/outbounding of goods, and the communication and collaboration of intelligent mobile robots (this latter based on the original ideas of the LIFE research team lead by the late Prof. T. Terano in the 1990-s), including dynamically changing scenarios with optimization aspects.

Human-Like Lifelong Machine Learning

Prof. Byoung-tak Zhang

Seoul National University, Korea

During the last decade machine learning technology, such as deep learning, has been very successful in many applications, including business analytics, text mining, speech recognition, computer vision, and autonomous robots. Machine learning is usually defined as a study of algorithms for automatically building models from observed data. However, this narrow definition does not reflect the full capability of humans as ideal learners. We should better pursue a “learning agent” that improves its performance through “acquisition of knowledge” from the “interaction” with the environment. This talk will critically review the state-of-the-art machine learning algorithms and argue for the need for human-like, lifelong machine learning to achieve human-level artificial intelligence. We will then present a learning architecture, the hypernetwork, that is designed to learn rapidly, flexibly, and robustly from sequentially observed data over an extended period of time. The hypernetwork model uses the sparse population coding principle borrowed from the biological brain and learned by a statistical-physical evolutionary algorithm. Applications will demonstrate the potential of hypernetworks for human-level machine learning: learning language from TV dramas, learning to compose music from digital albums, simulating children’s cognitive development of concept learning from cartoon videos, predicting mobile activities of smartphone users, user modeling with wearable devices, and learning from human activities to teach robots. Finally, we discuss why and how human-like lifelong machine learning can impact artificial intelligence, cognitive science, humanoid robotics, and smart service industries in the near future.

Visualization Method of Kansei Information based on Soft Computing Technology

Prof. Kaoru Hirota

Tokyo Institute of Technology, Japan

The presenters’ group at Tokyo Institute of Technology has been studying on various visualization methods of “Kansei" (affective computing) information in multi-agent society. The multi-agent society consists of many agents such as humans, machines, and/or robots, where they are supposed to be connected by internet and to communicate with each other. In the traditional study on such a communication including human-robot (or man-machine) interaction, mostly one to one communication has been stressed. In the near future, however, a society consisting of many humans and many robots (or machines) should be investigated, i.e., a multi-agent society. To realize smooth communication in such a multi-agent society, various topics should be investigated such as human-like higher level recognition mechanism and information time delay problem of internet. Among them one of the most important issues is “Kansei" information processing and their visualization methods which are stressed in this plenary talk. The “Kansei" engineering has been studied originally in Japan. Nowadays, as is known, “Kansei" is widely accepted in all over the world and is sometimes referred to affective engineering/computing. From the recent results of presenters’ group, three topics are selected and introduced in this plenary talk, i.e., “deep level emotion understanding", “fuzzy atmosfield", and “Kansei texture". The basic ideas and formalizations are mentioned first followed by visualization methods based on soft computing technology with several demonstration experiments.
