摘要

•We introduced an OReLU function, which is different from the existing nonlinear functions in D2NN.•We use genetic algorithm to optimize the threshold factor to achieve the highest classification accuracy.•The proposed OReLU is experimentally validated and the effect of experimental noise in such systems is evaluated.
