Abstract
:Aimed at the problem that e decrease th in population diversity of th e Sparrow Search Algorithm (SSA) e in th
t
later iterations is easy to lead the local extreme value solution of the m,the algorith distribution mutation strategy was in⁃
troduced to improve the SSA,and the improved SA was S used to optimize th e parameters of Variational Mode Decomposi⁃
tion(VMD),so as to obtain the optimal parameter combination e VMD of algorithm.C th ombining the improved SA S -VMD
algorithm ith w refined comp osite multi zzy-scale entropy fu ( RC MFE),the feature extraction of r
