Hello World!

Since I am too lonely at home with only books, movies, and games for company, I think that sharing my experiences would be a good idea. Whilst it would be cool to share what I know to all my readers, it is also a very good method to help me remember what I have done, for I always have a bad memory. Always. Literally.

In case I forget, let me review who I am, and what I am doing.

I am Jiaming Song (aka Tony Soong, or Tony, or whatever), currently a sophomore in Tsinghua University's Computer Science and Technology (aka CST) Department. Life in Tsinghua is awesome, you can never realize how cheap life can be! If one doesn't waste his money, he can survive in the school with $5 a day; also, great news for fitness-lovers: the gym costs only $1 each time, a fantastic price (only because it doesn't have treadmills or swimming pools. But this place will explode if they do, because there are so many people here in China!) Even better, the on-campus dorm I live in has an air conditioner and it costs $250 ... a year.(WHAT THE F**K!) I always wonder what foreigners would think of China after they come to Tsinghua (Good for you, Socialism?)

I'm very fond of Computer Science, and I'm interested in most aspects, but I currently find machine learning most fabulous. I plan to enter the lab that does Bayesian AI, so I am reading a book called Pattern Recognition and Machine Learning (Bishop), the beginners' guide to Bayesian AI. The concept of the Bayesian interpretation of probability is pretty interesting, but math seems to be a great problem. Although I've had calculus and linear algebra in my freshman year, the math used by all sorts of distributions(Gaussian, Beta, Dirichlet, Student's t, ... don't make me list all of them) required more, such as matrix derivatives, and variation calculus. So I'm pretty stuck at the previous chapters, and hopefully I could do better later.

// TODO(Tony) As for my hobbies, I decide to postpone them for later editing.
// TODO(Tony) I haven't revised my grammar, for I am soooo excited to type!
