“…Fuzzy logic plays an important role in biomedical signal analysis fields such as pattern recognition, computer vision, machine learning, image analysis, communication, knowledge discovery, and data mining [2,7,[10][11][12]28]. In the study reported in this paper, we formulated another related measure of time series complexity, i.e., fuzzy entropy (FuzzyEn), and applied it to characterize local muscle fatigue electromyography (EMG) signals.…”
