Softmax of a tensor.
k_softmax(x, axis = -1)
A tensor.
A tensor or variable.
The dimension softmax would be performed on. The default is -1 which indicates the last dimension.
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.).
