Takes LongTensor with index values of shape (*) and returns a tensor
of shape (*, num_classes) that have zeros everywhere except where the
index of last dimension matches the corresponding value of the input tensor,
in which case it will be 1.
Usage
nnf_one_hot(tensor, num_classes = -1)
Arguments
- tensor
(LongTensor) class values of any shape.
- num_classes
(int) Total number of classes. If set to -1, the number
of classes will be inferred as one greater than the largest class value in
the input tensor.
