Softsign activation function
http://nimblenet.readthedocs.io/en/latest/activation_functions.html Web11 Jul 2024 · The softplus function is a smooth approximation to the ReLU activation function, and is sometimes used in the neural networks in place of ReLU. softplus ( x) = log ( 1 + e x) It is actually closely related to the sigmoid function. As x → − ∞, the two functions become identical. sigmoid ( x) = 1 1 + e − x
