无需排列的排列熵计算方法

Calculating permutation entropy without permutations

Alexander Vidybida

AI总结:

本研究提出一种类排列熵的序列数据分析方法,无需组合运算且能保留嵌入向量等值信息,无等值分量时与排列熵结果一致,有等值分量时区分相似数据集精度更高。

摘要:

本文讨论了一种与排列熵方法类似的序列数据集分析方法。该方法的特点如下:它能保留嵌入向量中存在的等值信息;无需组合运算;当嵌入向量不含等值分量时,其输出的熵值与排列法完全一致,此时可使用该方法替代排列法。若嵌入向量存在等值分量,该方法在区分相似数据集时能够实现更高的精度。

英文摘要:

A method for analyzing sequential data sets, similar to the permutation entropy one, is discussed. The characteristic features of this method are as follows: it preserves information about equal values, if any, in the embedding vectors; it is exempt of combinatorics; it delivers the same entropy value as does the permutation method, provided the embedding vectors do not have equal components. In the latter case this method can be used instead of the permutation one. If embedding vectors have equal components this method could be more precise in discriminating between similar data sets.
