Update

update 2019/12/03

  After CS224n I realize that more systematical training is needed. So I start a new repo learn_NLP_again, here is the description(algorithms and solutions is available for chapter 1 until now):

  Here is why I started this project: learn NLP from scratch again. I choose Speech and language process as my entry point, and try to write solutions and implement some algorithms/models of this book. I hope I can stick to this project and update frequently.

  After one year's training in corporation and lab, I find many faults or incorrect habbits in past parctice, (btw, there is too many commits in this repo). I'll review the code in this repo and solve issues gradually.(😄, hopefully)

Welcome communications in new repo!
