Purpose: LDA 5hr Train Only for determining correct decode. Conducted on drone server Traubadix.

Details: 5hr Train with LDA and a specific parameter set for eliminating the randomness of LDA in the Train process. Purpose of this experiment is to verify the use of nonrandomness in the LDA Train process as well as "-lda" and "-ldadim" flags used in the decode process as well as the run_decode.pl and the run_decode_lda.pl - all three decodes to be conducted in separate experiments. Concucted on a 5hr train in this experiment with LDA of course turned on in the sphinx_train.cfg file before training on a 5hr corpus.

Results: COMPLETED.

Commands used in bold:

makeTrain.pl switchboard 5hr/train

cd /python/sphinx, then vi mllt.py. In line 101 within the "if, while" statement, "A = eye(s[0]) + 0.1 * random(s)", replace the "random(s)" with "0.5" so it looks like "A = eye(s[0]) + 0.1 * 0.5".

vi sphinx_train.cfg
 * change line 156 from no to yes
 * change line 158 from 29 to 32
