Member Data Documentation

int32 mgau_t::bstidx

Index for the most likely Gaussians in this mixture of component. It persists through time.

int32 mgau_t::bstscr

Scores for the most likely Gaussians in this mixture of component.

float32*** mgau_t::fullvar

float32* mgau_t::lrd

Log(Reciprocal(Determinant (variance))). (Then there is also a (2pi)^(veclen) involved...)

float32** mgau_t::mean

The n_comp means of the Gaussians. The mean vector for a single mixture-Gaussian model for one senone. Dimension: n_comp * dimension

int32* mgau_t::mixw

Mixture weights for the n_comp components (int32 instead of float32 because these values are in logs3 domain)

float32* mgau_t::mixw_f

(ONLY USED IN ENDPOINTER) mixture weights for the n_comp components in float32

int32 mgau_t::n_comp

#Component Gaussians in this mixture. NOTE: May be 0 (for the untrained states).

int32 mgau_t::updatetime

Update time

float32** mgau_t::var

The n_comp (diagonal) variances of the Gaussians. Could be converted to 1/(2*var) for faster computation (see above comment). The diagonal variance vector for a single mixture-Gaussian model for one senone. Dimension: n_comp * dimension
