tf.keras.backend.one_hot

Computes the one-hot representation of an integer tensor.

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

The one-hot tensor.
