SNR-adaptive bearing fault diagnosis using NRBO-optimized SVMD and kernel extreme learning machine

To overcome the problems such as the empirical parameters tuning, suboptimal feature selection, and poor classifier generalization in the existing bearing fault diagnosis methods, an NRBO - SVMD - KELM method is proposed in this paper. Newton-Raphson-based Optimizer (NRBO) adaptively optimizes the penalty factor of suc...
