... features using genetic algorithm for the diagnosis of a rotating machinery to prove the validity of this approach. Experimental results indicate that both diagnosis accuracy and robustness of diagnosis system can be improved by integrating different diagnosis methods and/or fault features. It is therefore...

... classifier parameters are optimized using a genetic algorithm. To reduce the computation cost, decrease the size, and enhance the reliability of the ANN, only the predominant wavelet transform scales are selected for features’ extraction. The results for both real and simulated bearing vibration data show...

... to achieve this purpose without sacrificing the array efficiency, the genetic algorithm (GA) is employed in the design stage to calculate the optimal array coefficients. The GA proved to be an effective technique in searching for the array coefficients that maximize the efficiency with desired flatness...
