Activation Functions in Neural Networks: Sigmoid, Tanh, ReLU, GELU
TL;DR: Why neural networks need activation functions. Sigmoid, tanh, ReLU, GELU and softmax in plain English, with a comparison table and a rule for choosing one. Here is a strange fact: you could stack 100 layers of a neural network and it would be exactly as powerful as a single layer. Sounds lik…
