WebThe whole idea behind the other activation functions is to create non-linearity, to be able to model highly non-linear data that cannot be solved by a simple regression ! ReLU. ReLU stands for Rectified Linear Unit. It is a widely used activation function. The formula is simply the maximum between \(x\) and 0 : \[f(x) = max(x, 0)\] WebRectifier (neural networks) Plot of the ReLU rectifier (blue) and GELU (green) functions near x = 0. In the context of artificial neural networks, the rectifier or ReLU (rectified linear unit) activation function [1] [2] is an activation function defined as the positive part of its argument: where x is the input to a neuron.
