Classes
struct	CommandAttributes
class	ComputationVariables
	This class relates the matrices and sub-matrices in the computation to imaginary "variables", such that we can think of the operations as operating on sets of individual variables, and we can then do analysis that lets us do optimization. More...
struct	Access
struct	MatrixAccesses
struct	Analyzer
	This struct exists to set up various pieces of analysis; it helps avoid the repetition of code where we compute all these things in sequence. More...
class	ComputationAnalysis
	This class performs various kinds of specific analysis on top of what class Analyzer gives you immediately. More...
struct	CheckComputationOptions
class	ComputationChecker

Namespaces
	kaldi
	This code computes Goodness of Pronunciation (GOP) and extracts phone-level pronunciation feature for mispronunciations detection tasks, the reference:
	kaldi::nnet3

Enumerations
enum	AccessType { kReadAccess, kWriteAccess, kReadWriteAccess }

Functions
void	PrintCommandAttributes (std::ostream &os, const std::vector< CommandAttributes > &attributes)
	This function is to be used in debugging; it produces human-readable output. More...
void	ComputeVariableAccesses (const ComputationVariables &variables, const std::vector< CommandAttributes > &command_attributes, std::vector< std::vector< Access > > *variable_accesses)
	After the command-level attributes have been computed, this function organizes them per variable (see class ComputationVariables for how a variable is defined; it is part of a matrix). More...
void	ComputeMatrixAccesses (const Nnet &nnet, const NnetComputation &computation, const ComputationVariables &variables, const std::vector< CommandAttributes > &command_attributes, std::vector< MatrixAccesses > *matrix_accesses)
	This function organizes information in the CommandAttributes in a way that is convenient to access per matrix. More...
void	PrintMatrixAccesses (std::ostream &os, const std::vector< MatrixAccesses > &matrix_accesses)
	This function is to be used in debugging; it produces human-readable output. More...
void	ComputeMatrixToSubmatrix (const NnetComputation &computation, std::vector< std::vector< int32 > > *mat_to_submat)
	This function computes a vector 'mat_to_submat', indexed by matrix index, such that (*mat_to_submat)[m] is a list of all the submatrix indexes that refer to matrix m. More...
int32	MaxMemoryUsage (const NnetComputation &computation)
	Returns the total memory, in bytes, used by the computation (just the temporary memory, not counting the memory used by the nnet itself). More...
void	ComputeCommandAttributes (const Nnet &nnet, const NnetComputation &computation, const ComputationVariables &vars, std::vector< CommandAttributes > *attributes)
void	GetCommandsOfType (const NnetComputation &computation, CommandType t, std::vector< int32 > *command_indexes)
	This utility function works out from a computation, the command-indexes of the commands of the given type. More...
void	CheckComputation (const Nnet &nnet, const NnetComputation &computation, bool check_rewrite=false)
	This is a convenience interface for class ComputationChecker. More...
int64	GetMaxMemoryUse (const NnetComputation &computation)
