Application of symmetric uncertainty and emperor penguin–grey wolf optimisation for feature selection in motor fault classification

open access: yesIET Electric Power Applications, Volume 18, Issue 10, Page 1107-1121, October 2024.
This paper presents an innovative model for motor fault diagnosis. The results can prove that proposed method can effectively reduce redundant features, improve the classification accuracy of feature subsets, and reduce running time. Abstract The authors present a model for diagnosing motor faults based on machine learning, demonstrating advantages ...
