WebJun 29, 2024 · The simplest activation function, one that is commonly used for the output layer activation function in regression problems, is the identity/linear activation function ( Figure 1, red curves): glinear(z) = z g l i n e a r ( z) = z. This activation function simply maps the pre-activation to itself and can output values that range (−∞,∞ ...
