ReLU

class torch.nn.ReLU(inplace: bool = False)[source]

Applies the rectified linear unit function element-wise:

ReLU(x)=(x)+=max(0,x)\text{ReLU}(x) = (x)^+ = \max(0, x)

Parameters

inplace – can optionally do the operation in-place. Default: False

Shape:
  • Input: (N,)(N, *) where * means, any number of additional dimensions

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

Examples:

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


An implementation of CReLU - https://arxiv.org/abs/1603.05201

  >>> m = nn.ReLU()
  >>> input = torch.randn(2).unsqueeze(0)
  >>> output = torch.cat((m(input),m(-input)))
