Centered and Averaged Fuzzy Entropy to Improve Fuzzy Entropy Precision. [PDF]
Entropy (Basel), 2018 Several entropy measures are now widely used to analyze real-world time series. Among them, we can cite approximate entropy, sample entropy and fuzzy entropy (FuzzyEn), the latter one being probably the most efficient among the three. However, FuzzyEn precision depends on the number of samples in the data under study.

Fuzzy Entropy-Based Spatial Hotspot Reliability. [PDF]
Entropy (Basel), 2021 Cluster techniques are used in hotspot spatial analysis to detect hotspots as areas on the map; an extension of the Fuzzy C-means that the clustering algorithm has been applied to locate hotspots on the map as circular areas; it represents a good trade-off between the accuracy in the detection of the hotspot shape and the computational complexity ...

Picture fuzzy cross-entropy for multiple attribute decision making problems
Journal of Business Economics and Management, 2016 In this paper, we investigate the multiple attribute decision making problems with picture fuzzy information. The advantage of picture fuzzy set is easily reflecting the ambiguous nature of subjective judgments because the picture fuzzy sets are suitable

Entropy of Fuzzy Partitions and Entropy of Fuzzy Dynamical Systems [PDF]
Entropy, 2016 In the paper we define three kinds of entropy of a fuzzy dynamical system using different entropies of fuzzy partitions. It is shown that different definitions of the entropy of fuzzy partitions lead to different notions of entropies of fuzzy dynamical ...
