Speech Title: Supervised Learning Fuzzy Discrete Event Systems
To effectively represent deterministic uncertainties and vagueness as well as human subjective observation and judgment encountered in many real-world problems especially those in medicine, we originated a theory of fuzzy discrete event systems (DES) in 2001. The theory is unique in that it is capable of modeling a class of event-driven systems as fuzzy automata with states and event-invoked state transitions being ambiguous. We introduced fuzzy states and fuzzy event transition and generalized conventional crisp DES to fuzzy DES. The largely graph-based framework of the crisp DES was unsuitable for the expansion and we thus reformulated it using state vectors and event transition matrices which could be extended to fuzzy vectors and matrices by allowing their elements to take values in [0, 1]. We also extended optimal control of DES to fuzzy DES. This novel fuzzy DES theory is consistent with the traditional DES theory, both at conceptual and computation levels, in that the former contains the latter as a special case when the membership grades are either 0 or 1. Other researchers have extended the FDES framework afterward. They studied a variety of fundamental FDES-related issues. These include supervisory control, observability, decentralized control, diagnosability, online control, state-based control, state-feedback control, prognosis, predictability, opacity, and detectabilities.
In this presentation, we show how a FDES can learn its event transition matrix, which is the core of the FDES, when neither pre-event nor post-event state is known. The only information assumes to be available is values of the variables and they are only known to be vaguely related to the pre- and post-event states. We link the variables to the states through Gaussian fuzzy sets owing to the conceptual relationship between a fuzzy set and a fuzzy state. The resulting innovative model is called the Fuzzy Automaton with Input and Output Fuzzy Sets (FAIOFS). Stochastic-gradient-descent-based algorithms are derived for the model to iteratively learn online the transition matrix and all the parameters of the fuzzy sets simultaneously. Another significant extension is that unlike our previous learning models, the new model is capable of determining an individual post-event state even if it is associated with two or more variables, expanding model’s utility. FAIOFS is the first fuzzy discrete event system model that is capable of learning solely based on sensor data without relying on any subjective input from humans, removing a significant bottleneck for real-world applications. Computer simulation results are furnished to exhibit learning performance of this new model.

Speech Title: Information Theory as a Unified Tool for Understanding and Designing Human-Computer Interaction
Information theory, particularly in a Bayesian context, has recently regained interest as a unified tool to understand and design human-computer communication and interaction. Like in everyday life, by continuously making predictions using previous experiences, the human-computer interaction should somehow aim at reducing the level of uncertainty (entropy), reinforcing true predictions and correcting wrong ones, via some feedback interaction loop. Taking the stance that human-computer interaction can be considered as a communication process, where uncertainty and information are described using information-theoretic terms, we can design interaction in such a way to optimize decisions under uncertainty.
In my presentation I will illustrate these concepts in the context of a Bayesian experimental design using an expected utility function, where the computer can "runs experiments" on the user by sending feedback that maximizes the expected gain of information by the computer, and exploits the users’ subsequent input to update its knowledge as interaction progresses. Applications to Fitts' law, fast file retrieval and multiscale navigation are given to illustrate the concepts.
