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. A sigmoid function is a mathematical function having a characteristic "S"-shaped curve or sigmoid curve. A common example of a sigmoid function is the logistic function shown in the first figure and defined by the formula: Other standard sigmoid functions are given in the Examples section. In some fi…
