Purpose of Activation Functions
easy
What is the purpose of an activation function in a neural network?
A
It introduces nonlinearity, enabling the network to learn complex non-linear mappings from inputs to outputs
B
It determines which neurons are active during a forward pass based on the magnitude of their inputs
C
It normalizes the output of each neuron to lie within a fixed range to prevent gradient instability during the forward pass
D
It computes the gradient of the loss with respect to each neuron's output during backpropagation
