NettetRectifier (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. Nettet23. mar. 2012 · 3.2.1 Boolean threshold functions. A Boolean function t defined on {0, 1} n is a Boolean threshold function, or simply a threshold function (sometimes known as a linear threshold function) if it is computable by a linear threshold unit.
