Functions
EventMap *	BuildTree (Questions &qopts, const std::vector< std::vector< int32 > > &phone_sets, const std::vector< int32 > &phone2num_pdf_classes, const std::vector< bool > &share_roots, const std::vector< bool > &do_split, const BuildTreeStatsType &stats, BaseFloat thresh, int32 max_leaves, BaseFloat cluster_thresh, int32 P, bool round_num_leaves=true)
	BuildTree is the normal way to build a set of decision trees. More...
EventMap *	BuildTreeTwoLevel (Questions &qopts, const std::vector< std::vector< int32 > > &phone_sets, const std::vector< int32 > &phone2num_pdf_classes, const std::vector< bool > &share_roots, const std::vector< bool > &do_split, const BuildTreeStatsType &stats, int32 max_leaves_first, int32 max_leaves_second, bool cluster_leaves, int32 P, std::vector< int32 > *leaf_map)
	BuildTreeTwoLevel builds a two-level tree, useful for example in building tied mixture systems with multiple codebooks. More...
void	GenRandStats (int32 dim, int32 num_stats, int32 N, int32 P, const std::vector< int32 > &phone_ids, const std::vector< int32 > &hmm_lengths, const std::vector< bool > &is_ctx_dep, bool ensure_all_phones_covered, BuildTreeStatsType *stats_out)
	GenRandStats generates random statistics of the form used by BuildTree. More...
void	ReadSymbolTableAsIntegers (std::string filename, bool include_eps, std::vector< int32 > *syms)
	included here because it's used in some tree-building calling code. More...
void	AutomaticallyObtainQuestions (BuildTreeStatsType &stats, const std::vector< std::vector< int32 > > &phone_sets_in, const std::vector< int32 > &all_pdf_classes_in, int32 P, std::vector< std::vector< int32 > > *questions_out)
	Outputs sets of phones that are reasonable for questions to ask in the tree-building algorithm. More...
void	KMeansClusterPhones (BuildTreeStatsType &stats, const std::vector< std::vector< int32 > > &phone_sets_in, const std::vector< int32 > &all_pdf_classes_in, int32 P, int32 num_classes, std::vector< std::vector< int32 > > *sets_out)
	This function clusters the phones (or some initially specified sets of phones) into sets of phones, using a k-means algorithm. More...
void	ReadRootsFile (std::istream &is, std::vector< std::vector< int32 > > *phone_sets, std::vector< bool > *is_shared_root, std::vector< bool > *is_split_root)
	Reads the roots file (throws on error). More...
