To address issues such as slow convergence and susceptibility to local optima in fault diagnosis using parallel ELM, an improved Coati Optimization Algorithm scheme is introduced to optimize the parameters of the parallel ELM. Through multiple comparative experiments, the superiority of the proposed method is validated in terms of diagnostic accuracy, prediction precision, convergence speed, and robustness. Experimental results demonstrate that the ICOA-optimized parallel ELM model achieves a diagnostic accuracy of 99.6% on the CWRU bearing dataset. Furthermore, under varying levels of interference, the ICOA-optimized parallel ELM exhibits strong robustness, significantly outperforming traditional optimization methods.
