Abstract: In this manuscript, we propose sum of steps approximation of a novel nonlinear activation function tunable ReLU for VLSI architecture implementation of neural networks. The characteristics of the proposed activation function depend on a tunable parameter and input data set values. Also, we propose a linear-in-the-parameter model for the proposed activation function using an even mirror Fourier nonlinear filter. Finally, simulation results are presented to show performance of the proposed activation function on various data sets and observe its superiority against to other activation functions.
