王伟讲课还是很清晰易懂的，个人感觉听recording质量比上课质量好。。。因为王伟语速很快humm一直听容易疲劳。。18S2感觉删掉了很多之前几届讲过的东西，替换成了deeplearning神经网络之类的，但是感觉课程还是不太够充实。proj用pytorch写的所以和其他用TensorFlow的课程又不太一样。期末考试不难，给分也比较和善。
6714跟自然语言处理有关，个人感觉比9318难一些(可能是因为和9417相互覆盖的地方比较多），作业量比9318少，18s2只有一个assignment和一个project。是根据Stanford的课来的，中科大有同款ppt
6714，这门课学的很多，最后考试题量很大，考试题还不太按给的考纲出，因为这门课的老师也是教Data Mining的老师，按照Data Mining的术语的话，你复习的时候由于只复习规定内容很可能会出现Over fitting，为了避免Over fitting，你平时上课要好好理解，好好记住老师讲的内容，尽量generalise学到的知识（学到的知识可以应用到不同问题），最后的Test Error Rate才会降低，分数才可以高点。

I am doing this course in 16s2
Really enjoying the algorithms and the contents in the lecture.
Lecturer(Wang Wei) is a nice person and a responsible teacher.
At the beginning few weeks of this semester, he looked bit nervous and cannot make the teaching content clear, speaking hundreds of "actually" in the 3 hours lecture, however, since week 4, he made a huge improvement, and I really enjoy the content and can not wait to take his lecture!
