HI, I am in Cosmos Scope Team in Bellevue working on distributed machine learning on an internal map-reduce infrastructure. Before this, I worked in BING Data Mining team and Microsoft Research Asia since 2005 as a Researcher in the Machine Learning group. My research interests include large scale machine learning, data mining, information retrieval and I enjoy employing them to solve industrial challenges, mostly in Web search and online advertising. I finished my PhD in HKUST and my PhD supervisor is Prof.Qiang Yang with a thesis on click model. Prior to joining Microsoft, I worked in IBM research lab for about one year.
My current research focus includes parallel machine learning and click model. My work in click model has been utilized by BING with achieving significant NDCG gains and acting as a sub-ranker since 2010 May. Meanwhile, my curiosity in data-driven research leads me to study parallel machine learning algorithms. We have published a toolkit, see SIGMA and SIGMA_AZURE. I also help the product team to parallelize the search ranking algorithm in BING and the CTR prediction algorithm in Ads Center R&R.
