Re: [Kaldi-users] Decoding result getting worse.

[Mailing l. u. f. U. C. a. U. <kal...@li...>]

There are some outputs that you can look at: in build_tree.log it
reports the objective-function improvement from splitting, if it's
working it should be 5 or 6 or so.  in lda_est.log (or est_lda.log?)
it reports the sum of eigenvalues which should be between 10 and 30
(more is better).  These values should increase during training.
Note: these values do not exist in the monophone stage.
