Hardtanh

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

Applies the HardTanh function element-wise.

HardTanh is defined as:

HardTanh(x)={max_val if x> max_val min_val if x< min_val x otherwise \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.

>>> input = torch.randn(2)
>>> output = m(input)
