FPGA Implementation for the Sigmoid with Piecewise Linear Fitting Method Based on Curvature Analysis
The sigmoid activation function is popular in neural networks, but its complexity limits the hardware implementation and speed. In this paper, we use curvature values to divide the sigmoid function into different segments and employ the least squares method to solve the expressions of the piecewise...
