Understanding neural network activation functions is essential whether you use an existing software tool to perform neural network analysis of data or write custom neural network code. This article ...

James McCaffrey explains what neural network activation functions are and why they're necessary, and explores three common activation functions. Understanding neural network activation functions is ...

Most of us probably have never used the hyperbolic tangent function tanh (x) or the sin (arctan (x)) reference function since our university days. But these functions enable a kinematic controller.
