Last week: got a better understanding of ASR with some papers; did some easy analysis about the weights of DNN already learned from Kaldi to see if some intersting things could be found and more regularization could be added to train a better DNN; the CONTEXT into DNN may be not enough, as the central frame is not highlighted and its neighbors should not share the same importance. Analysis of the first-layer weights may give some insight to improve the CONTEXT.

This week: do more analysis about the learned weights; improve the CONTEXT if possible, at least give it some small changes and contrast its performance with previous results.
