Speech Processing

AM development

Environment

  • grid-11 often shut down automatically, too slow computation speed.


RNN AM


Mic-Array

  • investigate alpha parameter in time domian and frquency domain
  • ALPHA>=0


Convolutive network

  • HOLD
  • CNN + DNN feature fusion

RNN-DAE(Deep based Auto-Encode-RNN)


Speaker ID

Ivector based ASR

Text Processing

tag LM

  • similar word extension in FST
  • check the formula using Bayes and experiment

RNN LM

  • rnn
  • code the character-lm using Theano
  • lstm+rnn
  • check the lstm-rnnlm code about how to Initialize and update learning rate.(hold)

W2V based doc classification

  • corpus ready
  • learn some benchmark.

Translation

  • v5.0 demo released
  • cut the dict and use new segment-tool

Sparse NN in NLP

  • prepare the ACL
  • check the code to find the problem .
  • increase the dimension
  • use different test set,but the result is not good.

online learning

  • data is ready.prepare the ACL paper
  • prepare sougouQ data and test it using current online learning method
  • baseline is not normal.
