WebApplies the rectified linear unit activation function. With default values, this returns the standard ReLU activation: max(x, 0), the element-wise maximum of 0 and the input tensor. Modifying default parameters allows you to use non-zero thresholds, change the max value of the activation, and to use a non-zero multiple of the input for values below the threshold. WebFeb 6, 2024 · An activation function transforms the sum of weighted inputs given to a node in a neural network using a formula. The process It helps the model to decide if a neuron can be activated and adds non-linearity to a neuron’s output, which enables it to learn in a better manner.
