The output layer is the layer in a neural network model that directly outputs a prediction. All feed-forward neural network models have an output layer. There are perhaps three activation functions you may want to consider for use in the output layer; they are: 1. Linear 2. Logistic (Sigmoid) 3. Softmax This is … See more This tutorial is divided into three parts; they are: 1. Activation Functions 2. Activation for Hidden Layers 3. Activation for Output Layers See more An activation functionin a neural network defines how the weighted sum of the input is transformed into an output from a node or nodes in a layer of the network. Sometimes the activation function is called a “transfer function.” … See more In this tutorial, you discovered how to choose activation functions for neural network models.
