An improved Cuckoo Search algorithm for LS-SVM optimization in bearing fault diagnosis based on signal decomposition and reconstruction

To improve the accuracy and robustness of bearing fault diagnosis, this paper proposes a fault diagnosis method based on Fast Ensemble Empirical Mode Decomposition (FEEMD) and a multi-strategy improved Cuckoo Search algorithm (Improved Cuckoo Search, ICS) optimized Least Squares Support Vector Machine (LS-SVM). In the...
