I am a 6th year Ph.D. student in the Department of Electrical and Computer Engineering at the University of California, San Diego, under the supervision of Prof. Gert Lanckriet.

Research Interests

I am broadly interested in scalable algorithms for ranking and retrieval. My current interests are in distance metric learning algorithms, structured prediction, and recommender systems.

Code

Robust-MLR (RMLR) code can be found here. It is implemented in the Metric Learning to Rank library, which is maintained by Brian McFee.

Fast Ranking via Metric Learning (FRML) code can be found here.
