Learning Rule for Time Delay in Fuzzy Cognitive Maps

概要

Time is considered as an important factor in modeling and operation of dynamic systems. However, few studies have considered time factor in modeling and inference of fuzzy cognitive maps (FCMs), besides, no studies have dealt with time delay in learning of FCMs. Therefore, we propose a learning rule for temporal FCMs involving post- and pre-delay time by extending Ojas learning rule. We show the effectiveness of the proposed rule through simulations which solve a time-delayed chemical plant control problem.
