torch.nn.functional.silu — PyTorch 2.7 documentation (original) (raw)

torch.nn.functional.silu(input, inplace=False)[source][source]¶

Apply the Sigmoid Linear Unit (SiLU) function, element-wise.

The SiLU function is also known as the swish function.

silu(x)=x∗σ(x),where σ(x) is the logistic sigmoid.\text{silu}(x) = x * \sigma(x), \text{where } \sigma(x) \text{ is the logistic sigmoid.}

See SiLU for more details.

Return type

Tensor

• torch.nn.functional.silu
  • silu()
