Help on NCE implementation

[giahung24]

Hello, I'm a newbie with torch and willing to make a simple version of DSSM. After looking around in your code, I found that (may be) you didn't implement the NCE criterion for the model. I tried to understand your code of MMI criterion but I coudn't. So can you help me by showing some cues how to calculate the NCE criterion (as in the DSSM paper)? Thank in advance!
