Puxuan Yu, 余璞轩

Hi there. I am a second-year MS/Ph.D. student from the Center for Intelligent Information Retrieval, and College of Information and Computer Sciences at University of Massachusetts Amherst. My advisor is Prof. James Allan.

My research interests lay in the intersection of information retrieval, machine learning and knowledge discovery.

Most recently, I am focused on (1) neural models for ad-hoc mono-lingual and cross-lingual IR; and (2) representation learning for personalized product search and recommendation. My past research projects include (1) intent-aware privacy protection for personalized web search; and (2) entity-related retrieval and extraction from unstructured data.
