torch_sigmoid(self)

Arguments

self

(Tensor) the input tensor.

sigmoid(input, out=NULL) -> Tensor

Returns a new tensor with the sigmoid of the elements of input.

$${\text{out}}_i=\frac{1}{1+e^{-{\text{input}}_i}}$$

Examples

if (torch_is_installed()) {

a = torch_randn(c(4))
a
torch_sigmoid(a)
