Abhinav Gupta

Heya! I am a final-year Ph.D. student at the Department of Computer Science and Operations Research in University of Montreal and part of Mila - Quebec AI Institute advised by Christopher Pal. My thesis is focused on investigating the phenomenon of emergent languages that arise in multi-agent communication systems.

I was fortunate to do research internships at Google DeepMind in London advised by Grzegorz Swirszcz, Wojciech Czarnecki, and Oriol Vinyals on opponent behavior modeling with offline AlphaStar; Meta AI in Seattle advised by Madian Khabsa and Roberta Raileanu on improving generalization in RL using uncertainty estimates; Microsoft Research NYC advised by Jordan Ash on replacing PPO with weighted SFT in RLHF; Labs team in Google Research at Mountain View advised by Navneet Potti on enhancing code correctness in LLMs through RL with execution feedback; Microsoft Research Cambridge working with Raluca Georgescu, Sam Devlin, and Katja Hofmann on learning human-like behavior using offline RL and imitation learning.

I received my Master's degree from Courant Institute of Mathematical Sciences at New York University. I was part of the CILVR Lab where I worked with Kyunghyun Cho on analyzing compositionality in emergent languages; Jason Weston on creating a unified model for QA/VQA tasks. I also interned at Adobe Research in San Jose advised by Scott Cohen and Brian Price on building an intelligent vision-language assistant. During my undergrad, I spent some time at the Language Technologies Institute in Carnegie Mellon University advised by Florian Metze (also at Meta AI) on context-aware speech recognition. I also spent a semester at the School of Computing in National University of Singapore working with Khe Chai Sim (now at Google Research) on visualizing activations of a live recorded audio using Kaldi.

Research

I'm interested in the intersection of reinforcement learning and language focusing on post-training, evaluation, and planning. My current interests include augmenting LLMs with multi-turn, tool-use, and self-critique capabilities to improve their mathematical reasoning; where tools could help enhance their factuality and code could be used to provide solutions to such problems.
