Activation Functions Used in Neural Networks Perspective The choice of nonlinear activation function has a key influence on the complexity and performance of artificial neural networks, note the term neural network will be used interchangeably with the term artificial neural network. The brief introduction to activation functions given in Chapter 3 is therefore extended. Although sigmoidal nonlinear activation functions are the most common choice, there is no strong a priori justification why models based on such functions should be preferred to others....
