gprune_none() is one of the functions to compute output probability of a set of Gaussian densities. This function does no pruning, just computing each Gaussian density one by one. For non tied-mixture model, this function is used as default. Specifying "-gprune none" at runtime can also select this function.

gprune_none() will be used by calling outprob_init() to set its pointer to the global variable compute_gaussset. Then it will be called from calc_tied_mix() or calc_mix().

Function Documentation

LOGPROB compute_g_base (  HTK_HMM_Dens *  binfo  )

Calculate probability of a Gaussian density against input vector on OP_vec. Parameters: binfo  [in] a Gaussian density Returns: the output log probability. Definition at line 58 of file gprune_none.c. Referenced by compute_gs_scores(), gprune_beam(), gprune_heu(), gprune_none(), and gprune_safe().

boolean gprune_none_init (   )

Initialize and setup work area for Gaussian computation Returns: TRUE on success, FALSE on failure. Definition at line 84 of file gprune_none.c. Referenced by outprob_init().

void gprune_none (  HTK_HMM_Dens **  g, int  num, int *  last_id )

Compute a set of Gaussians with no pruning. The calculated scores will be stored to OP_calced_score, with its corresponding mixture id to OP_calced_id. The number of calculated mixtures is also stored in OP_calced_num. This can be called from calc_tied_mix() or calc_mix(). Parameters: g  [in] set of Gaussian densities to compute the output probability. num  [in] length of above last_id  [in] ID list of N-best mixture in previous input frame, or NULL if not exist Definition at line 110 of file gprune_none.c. Referenced by outprob_init().
