Applies a softmin function.
Arguments
- input
(Tensor) input
- dim
(int) A dimension along which softmin will be computed (so every slice along dim will sum to 1).
- dtype
(
torch.dtype
, optional) the desired data type of returned tensor. If specified, the input tensor is casted todtype
before the operation is performed. This is useful for preventing data type overflows. Default: NULL.
Details
Note that
$$Softmin(x) = Softmax(-x)$$.
See nnf_softmax definition for mathematical formula.
