Ali Rahimi-Kalahroudi


My name is Ali Rahimi Kalahroudi (Written as "_علی رحیمی‌کلهرودی_" in my native language—Persian). I am currently a research assistant at Mila - Quebec AI under the supervision of Prof. Sarath Chandar.
My ultimate research goal is to develop AI agents capable of solving diverse tasks given minimal supervision.

I am currently interested in designing reliable machine learning (ML) algorithms for sequential decision-making in open-ended interaction settings. In these contexts, the algorithms must learn and continually adapt their skills and knowledge. To tackle these challenges, my approach centers on leveraging model-based learning mechanisms. This involves empowering AI agents with the capability to construct and utilize world models and employing planning to enhance their decision-making processes.

Bio: Perviously I received my M.Sc. in computer science at the University of Montreal and Mila.

Hobbies: While I am not doing science, I enjoy reading books, watching movies, playing football and volleyball, and hiking.
