Summary :

One of the reasons of slow convergence in Backpropagation learning is the diminishing value of the derivative of the commonly used activation functions as the nodes approach extreme values, namely, 0 or 1. In this letter, we propose arctangent activation function to accelerate learning speed. Simulation results indicate considerable improvement in convergence performance.
