WebThe function Tanh is the ratio of Sinh and Cosh. tanh = sinh cosh tanh = sinh cosh We can even work out with exponential function to define this function. tanh = ex−e−x ex+e−x … Tanh Activation is an activation function used for neural networks: f ( x) = e x − e − x e x + e − x. Historically, the tanh function became preferred over the sigmoid function as it gave better performance for multi-layer neural networks. But it did not solve the vanishing gradient problem that sigmoids suffered, which was tackled more ...
