Abstract: I have been studying Andrew Ng's (吴恩达) Machine Learning introduction class on Coursera. Needless to say, it is one of the best online Free course you can find on the Internet. So I want to share my learning curves with you by restating some key points that are really confusing in the class. Maybe I'm just stupid but not enough to stop sharing this. I also could've been wrong, so, please correct me if you find something. The goal of this post is trying to make you see through the terminologies quickly as well as reminding me these things in the future.
I will organize the blog using my notes above after I finished the Interview in next week.
