WebMar 16, 2024 · What is the Bipolar ReLu activation function used for? The squash activation function is also known as the BiPolar Relu function. Because it avoids the vanishing gradient problem, Bipolar Relu activation outperforms other activation functions such as sigmoid and tanh in neural network activation. 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.
