Functions
static void	GetIoNames (const std::vector< NnetExample > &src, std::vector< std::string > *names_vec)

static void	GetIoSizes (const std::vector< NnetExample > &src, const std::vector< std::string > &names, std::vector< int32 > *sizes)

static void	MergeIo (const std::vector< NnetExample > &src, const std::vector< std::string > &names, const std::vector< int32 > &sizes, bool compress, NnetExample *merged_eg)

void	MergeExamples (const std::vector< NnetExample > &src, bool compress, NnetExample *dest)
	Merge a set of input examples into a single example (typically the size of "src" will be the minibatch size). More...

void	ShiftExampleTimes (int32 t_offset, const std::vector< std::string > &exclude_names, NnetExample *eg)
	Shifts the time-index t of everything in the "eg" by adding "t_offset" to all "t" values. More...

void	GetComputationRequest (const Nnet &nnet, const NnetExample &eg, bool need_model_derivative, bool store_component_stats, ComputationRequest *computation_request)
	This function takes a NnetExample (which should already have been frame-selected, if desired, and merged into a minibatch) and produces a ComputationRequest. More...

void	WriteVectorAsChar (std::ostream &os, bool binary, const VectorBase< BaseFloat > &vec)

void	ReadVectorAsChar (std::istream &is, bool binary, Vector< BaseFloat > *vec)

void	RoundUpNumFrames (int32 frame_subsampling_factor, int32 num_frames, int32 num_frames_overlap)

int32	GetNnetExampleSize (const NnetExample &a)
	This function returns the 'size' of a nnet-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...
