One goal of automation is to mimic the smoothness and efficiency of human performance. Fuzzy logic based soft computing and engineering works towards this goal. The obvious difference between machines and humans is that of life. If one could understand the method by which human perception and motor response takes place one might conceive of a means to automate these capabilities. The anatomy and physiology...
In this paper, a novel feature extraction method based on the utilization of wavelet packet transform (WPT) and the concept of fuzzy entropy is presented. The method acts in steps, were in the first step the WPT is employed to generate a wavelet decomposition tree from which many features are extracted. In the second step, a new algorithm to compute the fuzzy entropy is developed and adopted as a...
Fuzzy entropy (FuzzyEn), a new measure of time series regularity, was proposed and applied to the characterization of surface electromyography (EMG) signals. Similar to the two existing related measures ApEn and SampEn, FuzzyEn is the negative natural logarithm of the conditional probability that two vectors similar for m points remain similar for the next m+1 points. Importing the concept of fuzzy...
