I am a PhD candidate in Computer Science, School of Informatics, Computing and Engineering, Indiana University Bloomington. My research interests lie in statistical machine learning, optimization and reinforcement learning. I am now working with Dr. Martha White, mainly on representation learning with regularized Dictionary Learning.
Far better an approximate answer to the right question, which is often vague, than an exact answer to the wrong question, which can always be made precise. --John W. Tukey, The future of data analysis.
Diversity is essential to happiness. --Bertrand Russell, A History of Western Philosophy.
All cowardice comes from not loving or not loving well, which is the same thing. --Woody Allen, Midnight in Paris.
Learning something while forgetting all of them in the future is totally different from not to learn them at all. -- A teacher during my high school.

I love soccer, basketball and baseball. In my spare time, I watch games and play them. I also like playing the guitar, video games, and reading books and manga.
