Functions
void	ComputeDiscriminativeObjfAndDeriv (const DiscriminativeOptions &opts, const TransitionModel &tmodel, const CuVectorBase< BaseFloat > &log_priors, const DiscriminativeSupervision &supervision, const CuMatrixBase< BaseFloat > &nnet_output, DiscriminativeObjectiveInfo *stats, CuMatrixBase< BaseFloat > *nnet_output_deriv, CuMatrixBase< BaseFloat > *xent_output_deriv)
	This function does forward-backward on the numerator and denominator lattices and computes derivates wrt to the output for the specified objective function. More...
