Classes
struct	NnetDiscriminativeSupervision
struct	NnetDiscriminativeExample
	NnetDiscriminativeExample is like NnetExample, but specialized for sequence training. More...
struct	NnetDiscriminativeExampleStructureHasher
	This hashing object hashes just the structural aspects of the NnetExample without looking at the value of the features. More...
struct	NnetDiscriminativeExampleStructureCompare
	This comparator object compares just the structural aspects of the NnetDiscriminativeExample without looking at the value of the features. More...
class	DiscriminativeExampleMerger
	This class is responsible for arranging examples in groups that have the same strucure (i.e. More...

Functions
void	MergeDiscriminativeExamples (std::vector< NnetDiscriminativeExample > *input, bool compress, NnetDiscriminativeExample *output)
	Appends the given vector of examples (which must be non-empty) into a single output example. More...
void	MergeSupervision (const std::vector< const NnetDiscriminativeSupervision *> &inputs, NnetDiscriminativeSupervision *output)
void	ShiftDiscriminativeExampleTimes (int32 frame_shift, const std::vector< std::string > &exclude_names, NnetDiscriminativeExample *eg)
	Shifts the time-index t of everything in the input of "eg" by adding "t_offset" to all "t" values– but excluding those with names listed in "exclude_names", e.g. More...
void	GetDiscriminativeComputationRequest (const Nnet &nnet, const NnetDiscriminativeExample &eg, bool need_model_derivative, bool store_component_stats, bool use_xent_regularization, bool use_xent_derivative, ComputationRequest *computation_request)
	This function takes a NnetDiscriminativeExample and produces a ComputationRequest. More...
int32	GetDiscriminativeNnetExampleSize (const NnetDiscriminativeExample &a)
	This function returns the 'size' of a discriminative example as defined for purposes of merging egs, which is defined as the largest number of Indexes in any of the inputs or outputs of the example. More...
