Hardtanh¶

class paddle.nn. Hardtanh ( min=- 1.0, max=1.0, name=None ) [source]

Hardtanh Activation. Create a callable object of Hardtanh.

\[\begin{split}Hardtanh(x)= \left\{ \begin{array}{cll} max,& & \text{if } x > max \\ min,& & \text{if } x < min \\ x,& & \text{otherwise} \end{array} \right.\end{split}\]

Parameters

• min (float, optional) – The value of min for Hardtanh. Default is -1.

• max (float, optional) – The value of max for Hardtanh. Default is 1.

• name (str, optional) – Name for the operation (optional, default is None). For more information, please refer to Name.

Shape:

• input: Tensor with any shape.

• output: Tensor with the same shape as input.

Examples

import paddle

x = paddle.to_tensor([-1.5, 0.3, 2.5])
m = paddle.nn.Hardtanh()
out = m(x) # [-1., 0.3, 1.]

forward ( x )

forward¶

Defines the computation performed at every call. Should be overridden by all subclasses.

Parameters

• *inputs (tuple) – unpacked tuple arguments

• **kwargs (dict) – unpacked dict arguments
