AM development

Sparse DNN

  • Optimal Brain Damage(OBD).
  1. Online OBD held.
  2. OBD + L1 norm start to investigation.


Engine optimization

  • Constant FST Applied. Original RT (GCC + vector FST): 0.35. Optimized (GCC+const FST + cache): 0.29
  • Start to investigate LOUDS FST.
  • Investigate spare computing

English NN training

  • WSJ+Chinglish data training, done
  • 300 English song graph. Looks fine.
  • Preparing test.


LM development

NN LM

  • 3 iteration 500 M training done. 24 hours per iteration.
  • PPL 189 after 3 iterations.
  • NN-based CSLM merge done (10240*100*10240). The PPL and WER are both worse than the original 10 network outputs.
  • Need to investigate why the merge is not accurate.


Embedded development

  • Embedded stream mode preparing.
