WebNov 10, 2024 · Permutation Entropy is an alternate entropy defined by Christoph Band and Bernd Pompe's Permutation entropy: a natural complexity measure for time series in Physical Review Letters, 2002 (paywalled).
WebJun 20, 2024 · Permutation entropy is an effective index which can be used to describe the dynamic complexity of a time series, and it can effectively enlarge the small changes of a sequence. WebFor the first time, the concept of a nonlinear entropy metric -permutation entropy- is extended, from unidimen-sional time series and two-dimensional images to data residing on the vertices of (irregular) undirected graphs. We explore how the permutation entropy of graph signals depends on both the signal and the graph. We also give
