Sigmoid activation function คือ
WebSiLU. class torch.nn.SiLU(inplace=False) [source] Applies the Sigmoid Linear Unit (SiLU) function, element-wise. The SiLU function is also known as the swish function. \text {silu} (x) = x * \sigma (x), \text {where } \sigma (x) \text { is the logistic sigmoid.} silu(x) = x∗σ(x),where σ(x) is the logistic sigmoid. WebJun 9, 2024 · Sigmoid is the most used activation function with ReLU and tanh. It’s a non-linear activation function also called logistic function. The output of this activation function vary between 0 and 1. All the output of neurons will be positive. The corresponding code is as follow: def sigmoid_active_function(x): return 1./(1+numpy.exp(-x))
