Functions
void	InitFmllr (int32 dim, Matrix< BaseFloat > *out_fmllr)
BaseFloat	ComputeFmllrDiagGmm (const FmllrDiagGmmAccs &accs, const FmllrOptions &opts, Matrix< BaseFloat > *out_fmllr, BaseFloat *logdet)

BaseFloat	ComputeFmllrMatrixDiagGmmFull (const MatrixBase< BaseFloat > &in_xform, const AffineXformStats &stats, int32 num_iters, MatrixBase< BaseFloat > *out_xform)
	Updates the FMLLR matrix using Mark Gales' row-by-row update. More...
BaseFloat	ComputeFmllrMatrixDiagGmmDiagonal (const MatrixBase< BaseFloat > &in_xform, const AffineXformStats &stats, MatrixBase< BaseFloat > *out_xform)
	This does diagonal fMLLR (i.e. More...
BaseFloat	ComputeFmllrMatrixDiagGmmDiagonal2 (const MatrixBase< BaseFloat > &in_xform, const AffineXformStats &stats, MatrixBase< BaseFloat > *out_xform)
BaseFloat	ComputeFmllrMatrixDiagGmmOffset (const MatrixBase< BaseFloat > &in_xform, const AffineXformStats &stats, MatrixBase< BaseFloat > *out_xform)
	This does offset-only fMLLR, i.e. it only estimates an offset. More...
BaseFloat	ComputeFmllrMatrixDiagGmm (const MatrixBase< BaseFloat > &in_xform, const AffineXformStats &stats, std::string fmllr_type, int32 num_iters, MatrixBase< BaseFloat > *out_xform)
	This function internally calls ComputeFmllrMatrixDiagGmm{Full, Diagonal, Offset}, depending on "fmllr_type". More...
float	FmllrAuxFuncDiagGmm (const MatrixBase< float > &xform, const AffineXformStats &stats)
	Returns the (diagonal-GMM) FMLLR auxiliary function value given the transform and the stats. More...
double	FmllrAuxFuncDiagGmm (const MatrixBase< double > &xform, const AffineXformStats &stats)
BaseFloat	FmllrAuxfGradient (const MatrixBase< BaseFloat > &xform, const AffineXformStats &stats, MatrixBase< BaseFloat > *grad_out)
	Returns the (diagonal-GMM) FMLLR auxiliary function value given the transform and the stats. More...
void	ApplyFeatureTransformToStats (const MatrixBase< BaseFloat > &xform, AffineXformStats *stats)
	This function applies a feature-level transform to stats (useful for certain techniques based on fMLLR). More...
void	ApplyModelTransformToStats (const MatrixBase< BaseFloat > &xform, AffineXformStats *stats)
	ApplyModelTransformToStats takes a transform "xform", which must be diagonal (i.e. More...
void	FmllrInnerUpdate (SpMatrix< double > &inv_G, VectorBase< double > &k, double beta, int32 row, MatrixBase< double > *transform)
	This function does one row of the inner-loop fMLLR transform update. More...
