The permutation entropy
Webb30 okt. 2024 · Permutation entropy is a global information measure, hence insensitive to the permutation ordering scheme. permutation_entropy: A function to compute the … WebbWhen considering the transition probability matrix of ordinal patterns, transition permutation entropy (TPE) can effectively extract fault features by quantifying the irregularity and complexity of signals. However, TPE can only characterize the complexity of the vibration signals at a single scale. Therefore, a multiscale transition permutation …
