I am a second-year Ph.D. student in the Electrical Engineering Department at Columbia University, as part of the LabROSA, working with Professor Dan Ellis. My CV is available here, as of Aug 2013. Prior to that, I obtained my master's degree in Music and Technology program at Carnegie Mellon University, working with Professor Roger Dannenberg in the School of Computer Science, where I was part of the Computer Music Group.

Here are some notes regarding some topics I found interesting. I wrote these just for fun (and I think they will be useful sometime in the future). Therefore, there might be mistakes/errors in these notes. If you find any problem, please let me know.
A proof that Maximum Likelihood Estimation (MLE) is biased for variance estimator.
A note that shows some useful properties for matrix derivative.
Some technical details for the Expectation Maximization (EM) algorithm.
Besides hacking and research, I am interested in art, especially music. I play piano and keyboard synthesizer. I participated in several bands during undergrad as keyboardist: a Pink Floyd tribute band named 'Outside the Wall’ and an original progressive rock band which composed several original songs.
