What Does Activation Function Mean?
An activation function is the function in an artificial neuron that delivers an output based on inputs. Activation functions in artificial neurons are an important part of the role that the artificial neurons play in modern artificial neural networks.
Techopedia Explains Activation Function
One way to understand the activation function is to look at a visual “model” of the artificial neuron. The activation function is at the “end” of the neural structure, and corresponds roughly to the axon of a biological neuron.
