Shangjia,

I re-edited a couple parts of the paper. It looks good. I just highlighted in green a few parts I don't feel like I understand. Also, the discussion doesn't seem to relate to our problem. We only have two classes, but the last paragraph is mostly about it's problem with more than 2 classes.

Also, I think we need to write a lot more about the findings. the graphs aren't really explained or anything.
