Abhimanyu Lad Fifth year PhD student Language Technologies Institute, School of Computer Science, Carnegie Mellon University, 5000 Forbes Avenue, Pittsburgh, PA 15213. alad [at] cs cmu edu I am a fifth year PhD student at the Language Technologies Institute, advised by Prof Yiming Yang. Currently I am working on joint probabilistic modeling of regression, classification, and retrieval tasks using graphical models, and optimal ordering of a sequence of such interrelated tasks to maximize overall utility. I did my summer internship at Yahoo! Santa Clara, under Jan Pedersen, on machine learning approaches to ranking, aka learning to rank for IR. Thanks to Yahoo! for supporting my research through the Yahoo! PhD Fellowship for 2007-09. See my curriculum vitae, or short resume. I received my B.Tech. in Information Technology from IIIT Allahabad, India in 2005. Research Interests Statistical machine learning, algorithms for text retrieval and web data processing.
