The decomposition is obtained for each value MWPE BLIMF as multiscale feature amount of the signal, wherein the number of samples MWPE value N, the scale factor s, delay embedding dimension m and time-dependent. <br>Considering the multi-scale weighted permutation entropy permutation entropy special form s = 1, and the multi-scale weighted permutation entropy calculation depends on the value of WPE, the WPE of the selected parameters discussed first. Document according to formula [8], this delay time is set,

The MWPE value obtained for each BLIMF after decomposition is taken as the multi-scale characteristic of the signal, wherein the MWPE value is related to the sample size N, scale factor s, embedded dimension m and delay time.<br>Considering that weighted arrangement entropy is a special form of multi-scale arrangement entropy s1, and that multi-scale weighted arrangement entropy mainly depends on the calculation of WPE values, the parameter selection of WPE is discussed first. This article set the delay time to , as shown in the literature .

The mwpe value obtained for each blimf after decomposition is taken as the multi-scale feature of the signal, and the mwpe value is related to the number of samples n, scale factor s, embedding dimension m and delay time.<br>Considering that the weighted permutation entropy is a special form of the multi-scale permutation entropy S = 1, and the multi-scale weighted permutation entropy mainly depends on the calculation of the WPE value, this paper first discusses the parameter selection of WPE. According to the reference [8], the delay time is set as,
