One of the important components of an artificial neural network (ANN) is the activation function. This paper discusses properties of activation functions in multilayer neural network applied to breast cancer stage classification. There are a number of common activation functions in use with ANNs. The...

In this paper, we propose an improved activation function, which we name the natural-logarithm-rectified linear unit (NLReLU). This activation function uses the parametric natural logarithmic transform to improve ReLU and is simply defined as. NLReLU not only retains the sparse activation ...
