mindspore.Tensor.sigmoid
- Tensor.sigmoid()[source]
Sigmoid activation function.
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 the self tensor.
- Returns
Tensor, with the same type and shape as the self tensor.
- Raises
TypeError – If dtype of self tensor is not float16, float32, float64, complex64 or complex128.
- Supported Platforms:
Ascend
GPU

Examples
>>> input_x = Tensor(np.array([1, 2, 3, 4, 5]), mindspore.float32) >>> output = input_x.sigmoid() >>> print(output) [0.7310586 0.880797 0.95257413 0.98201376 0.9933072 ]
