Speech:Exps 0283 018

Description
Authors: Jon Shallow James Schumacher

Date: 4/01/16

Purpose: Emacs was accidentally installed on Caesar and the concern now is that there may have been Sphinx related files that were overwritten. This test is being performed to determine if training results have been altered as a result of this Emacs incident. To determine if the Emacs incident affected training, the results of this experiment will be compared to experiment 0283/015 (pre Emacs incident era). These two trains have identical sphinx_train.cfg files with the exception being the paths.

Details:
 * Train configuration
 * Corpus: /mnt/main/corpus/switchboard/145hr
 * $CFG_VARNORM = 'no' (variance normalization)
 * $CFG_FINAL_NUM_DENSITIES = 8 (density)
 * $CFG_N_TIED_STATES = 1000 (senones)
 * $CFG_CONVERGENCE_RATIO = 0.04 (convergence ratio)
 * Train start: 8:16 PM 01 Apr 16
 * Train end: 3:08 AM 02 April 16
 * Decode configuration
 * Decoding on: /mnt/main/corpus/switchboard/145hr/test/trans/train.trans
 * Decoding at: 1000 senones to match the senone count in the train configuration
 * Decode start: 10:21 AM 02 April 16
 * Decode end: 12:00 PM 02 April 16

 * These results matched up perfectly to Experiment 0283/015.

Further proof that the Emacs incident had no adverse effect on training: [jrs1036@caesar 018]$ diff /mnt/main/Exp/0283/015-OFF/etc/scoring.log ./etc/scoring.log 2c2 < Begin alignment of Ref File: '015_train.trans' and Hyp File: 'hyp.trans' ---   > Begin alignment of Ref File: '018_train.trans' and Hyp File: 'hyp.trans'


 * The only difference between the files is the name of the .trans file. This is good.
