This article studies efficient data transmission, or "data compression", from the standpoint of the theory of epsilon entropy. The notion of the entropy of a "data source" is defined. This quantity ...

Physics The universe tends towards disorder. But how come nobody knows why? Entropy is the physicist’s magic word, invoked to answer to some of the biggest questions in cosmology. Yet a quantum ...

Aiming at accurately identifying shearer cutting patterns, this article proposes a new feature extraction method based on improved local mean decomposition (LMD) and multi-scale fuzzy entropy (MFE).
