Computes the one-hot representation of an integer tensor.

`k_one_hot(indices, num_classes)`

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

- indices
nD integer tensor of shape

`(batch_size, dim1, dim2, ... dim(n-1))`

- num_classes
Integer, number of classes to consider.

This function is part of a set of Keras backend functions that enable lower level access to the core operations of the backend tensor engine (e.g. TensorFlow, CNTK, Theano, etc.).
