nnf_one_hot function

One_hot

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.

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.
