The most common activation functions can be divided in three categories: ridge functions, radial functions and fold functions. An activation function is saturating if . It is nonsaturating if it is not saturating. Non-saturating activation functions, such as ReLU, may be better than saturating activation functions, as they don't suffer from vanishing gradient.
