Interests

My core research interest is in machine learning for interactive systems that maximizes a utility function by taking actions, which is in contrast to prediction-oriented machine learning like supervised learning. I am working on large language models, reinforcement learning, contextual bandits, and related areas. My work has been applied to industrial recommendation, Web search, advertising, and conversational systems at leading companies.

Most of my work can be grouped into several clusters:

More information can be found in Google Scholar, DBLP, LinkedIn.

Somewhat up-to-date CV, and short bio.

I am also on Twitter as @LihongLi20.
