class ClassLLCriterion

This criterion can be used to train *in classification* a GradientMachine object using the GMTrainer trainer.

Documentation

This criterion can be used to train *in classification* a GradientMachine object using the GMTrainer trainer. It then maximizes the log likelihood of the data.

If we write for the output of the GradientMachine, it supposes that

o ClassLLCriterion(ClassFormat* class_format)
The ClassFormat is needed just to know how the targets are encoded in the data
