Documentation

SoftMax layer for GradientMachine.

The number of inputs/outputs is the number of units in the machine.

Formally speaking, where .

Options:

"shift"	real	shift to avoid overflow	[0]
"compute shift"	bool	compute shift to avoid overflow	[false]

(you can have the "shift" you want, if you want, or you can automatically compute the shift)

SoftMax(int n_units)

Create a layer with n_units units

This class has no child classes.
