Johannes Schmidt-Hieber, NONPARAMETRIC REGRESSION USING DEEP NEURAL NETWORKS WITH RELU ACTIVATION FUNCTION, The Annals of Statistics, Vol. 48, No. 4 (August 2020), pp. 1875-1897 ...

So this kind of activation function says the neuron gives n degree of probability to the outcome yes or no. You can see the output of a sigmoid function in the graph in Figure 3.

Understanding how to use non-standard activation functions allows you to customize a neural network system. A neural network loosely models biological synapses and neurons. Neural network (NN) ...

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 ...
