   @ pengzhao-intel 
   We see the regression happening on LSTM on PTB data with symbolic training 
   The graph shows that training & validation perplexity increased starting from 11/28 , which is matching with the date of fix of LSTM regression issue. 
   We do see improvement in speed. There is huge drop in training time which I am skeptical about.
