Hi, I'm a 6th year PhD student at LTI. My advisor is Jaime G. Carbonell
My thesis defense date is March 15th, 2010. The title of my thesis is "ProActive Learning: Towards Cost-Sensitive Active Learning with Multiple Imperfect Predictors".
Here is my Resume

Research

• My research interests are proactive learning, active learning, rank learning, semi-supervised learning, and information retrieval in general.


• I mainly work on proactive and active learning algorithms and their applications in different areas including classification, and rank learning.


• Recently, I have become interested in unsupervised and accurate learning for classification in the absence of gold standard labels.


• In the summer of 2008, I was a research intern at the Text Mining, Search and Navigation group at Microsoft Research. My mentors were Krysta Svore and Chris Burges.

Awards

• I have been a recipient of the Yahoo Key Scientific Challenges Award Program 2009-2010 in the area of Machine Learning.
