About Profit Sharing Considering Infatuate Actions

Wataru Uemura

Abstract: In reinforcement learning systems based on trial-and error, the agent, that is the subject or the system that perceives its environment and takes actions which maximize its chances of success, is rewarded when it attains the target level of learning of the learning exercise. In Profit Sharing, the reinforcement learning process is pursued for the accumu...<more>

Information Theoretic Approach for Measuring Interaction in Multiagent Domain

Sachiyo Arai and Yoshihisa Ishigaki

Abstract: Although a large number of reinforcement learning algorithms have been proposed for the generation of cooperative behaviors, the question of how to evaluate mutual benefit or loss among them is still open. As far as we know, an emerged behavior is regarded as a cooperative behavior when embedded agents have finally achieved their global goal, regardless...<more>

An Application of Rough Set Analysis toa Psycho-Physiological Study - Assessing the RelationBetween Psychological Scale and Immunological Biomarker

Shusaku Nomura and Yasuo Kudo

Abstract: This study aims at an application of rough set theory to illustrate the relationship between human psychological and physiological states. Recent behavioral medicine studies have revealed that various human secretory substances change according to mental states. These substances, the hormones and immune substances, show temporal increase against mental ...<more>

Multiobjective Random Fuzzy Linear Programming Problems Based on the Possibility Maximization Model

Takashi Hasuike, Hideki Katagiri, and Hiroaki Ishii

Abstract: Two multiobjective random fuzzy programming problems considered based on the possibility maximization model using possibilistic and stochastic programming are not initially well defined due to the random variables and fuzzy numbers included. To solve them analytically, probability criteria are set for objective functions and chance constraints are intro...<more>

Operation Planning of District Heating and Cooling Plants Considering Contract Violation Penalties

Kosuke Kato, Masatoshi Sakawa, Keiichi Ishimaru, and Satoshi Ushiro

Abstract: Urban district heating and cooling (DHC) systems operate large freezers, heat exchangers, and boilers to stably and economically supply hot and cold water, steam, etc., based on customer demand. We formulate an operation-planning problem as a nonlinear integer programming problem for an actual DHC plant. To reflect actual decision making appropriately, ...<more>

A Normative Approach to Fuzzy Logic Reasoning Using Residual Implications

Yahachiro Tsukamoto

Abstract: Logical problems with fuzzy implications have been investigated minutely (Baczynski and Jayaram [1]). Considering some of the normative criteria to be met by generalized modus ponens, we have formulated a method of fuzzy reasoning based on residual implication. Among these criteria, the specificity possessed by the conclusion deduced by generaliz...<more>
