This paper describes a step gain optimization method of an adaptive noise canceller (ANC) using Normalized Least Mean Squares (NLMS) algorithm. This is useful for a speech recognition system (SRS). In this proposed method, a stepgain is made optimized by means of a fuzzy inference system (FIS). Results of experiments using data in a running car (50[kmIh])(More)

In this paper we propose a chaos dynamic memory model applied to the chaotic autoassociation memory. The present artificial neuron model is properly characterized in terms of a time-dependent sinusoidal activation function to involve a transient chaotic dynamics as well as the energy steepest descent strategy. It is elucidated that the present neural(More)
