Sigmoid(Logistic) Activation Function. Hyperbolic Tangent (tanh) Activation. Rectified Linear Unit (ReLU) Activation. Leaky ReLU Activation. Softmax Activation. (1) What Is An Activation Function? An activation function is a mathematical function that determines the output of a neuron or a layer of neurons in a neural network. It introduces non-linearity into the network, allowing it to model complex relationships and make non-linear transformations of the input data. (2) Why To Use Activation Function?
