Hardtanh

class torch.nn.Hardtanh(min_val=- 1.0, max_val=1.0, inplace=False, min_value=None, max_value=None)

Applies the HardTanh function element-wise.

HardTanh is defined as:

$$\text{HardTanh}(x) = \begin{cases} \text{max\_val} & \text{ if } x > \text{ max\_val } \\ \text{min\_val} & \text{ if } x < \text{ min\_val } \\ x & \text{ otherwise } \\ \end{cases}$$

Parameters:

• min_val (float) – minimum value of the linear region range. Default: -1

• max_val (float) – maximum value of the linear region range. Default: 1

• inplace (bool) – can optionally do the operation in-place. Default: False

Keyword arguments min_value and max_value have been deprecated in favor of min_val and max_val.

Shape:

• Input: $(*)$, where $*$ means any number of dimensions.

• Output: $(*)$, same shape as the input.

Examples:

>>> m = nn.Hardtanh(-2, 2)
>>> input = torch.randn(2)
>>> output = m(input)
