mindspore.mint.sigmoid

mindspore.mint.sigmoid(input)

Computes Sigmoid of input element-wise. The Sigmoid function is defined as:

$$\text{sigmoid}(x_i)=\frac{1}{1+\exp (-x_i)}$$

where $x_i$ is an element of x.

Parameters

input (Tensor) – input is $x$ in the preceding formula. Tensor of any dimension, the data type is float16, float32, float64, complex64 or complex128.

Returns

Tensor, with the same type and shape as the input.

Raises

• TypeError – If dtype of input is not float16, float32, float64, complex64 or complex128.

• TypeError – If input is not a Tensor.
