Computes the one-hot representation of an integer tensor.

k_one_hot(indices, num_classes)



nD integer tensor of shape (batch_size, dim1, dim2, ... dim(n-1))


Integer, number of classes to consider.


(n + 1)D one hot representation of the input with shape (batch_size, dim1, dim2, ... dim(n-1), num_classes)
