Athul Paul Jacob
I am a Ph.D. student in AI, multi-agent systems and, NLP at MIT CSAIL, advised by Jacob Andreas. I received my master's degree from MIT EECS in 2022, where my thesis was co-advised by Noam Brown and Jacob Andreas.
In 2019, I completed my bachelor's in computer science, combinatorics and optimization at the University of Waterloo, where I was advised by Pascal Poupart. From 2016 until 2018, I was also a visiting student researcher at Mila where I worked under the supervision of Yoshua Bengio.
I have been fortunate to intern at Facebook AI Research several times in 2018, 2020 and 2021 as a researcher, where I was mentored by Noam Brown, Kyunghyun Cho and Mike Lewis. I have also previously worked as a research intern at Microsoft Research in fall 2017 and winter 2018 with Alessandro Sordoni and Adam Trischler. I have also spent time at Google, MIT-IBM Watson AI Lab and General Catalyst Venture Partners as an AI Fellow.

Modeling Boundedly Rational Agents with Latent Inference Budgets
Athul Paul Jacob,
Abhishek Gupta,
Jacob Andreas
International Conference on Learning Representations (ICLR), 2024
NeurIPS Generalization in Planning Workshop , 2023
We study the problem of modeling a population of agents pursuing unknown goals subject to unknown computational constraints. We introduce latent inference budget model (L-IBM) that models agents’ computational constraints explicitly, via a latent variable (inferred jointly with a model of agents’ goals) that controls the runtime of an iterative inference algorithm. In three modeling tasks—inferring navigation goals from routes, inferring communicative intents from human utterances, and predicting next moves in human chess games—we show that L-IBMs match or outperform Boltzmann models of decision-making under uncertainty

Regularized Conventions: Equilibrium Computation as a Model of Pragmatic Reasoning
Athul Paul Jacob,
Gabriele Farina,
Jacob Andreas
Arxiv, 2023
We present a model of pragmatic language understanding called ReCo, where utterances are produced and understood by searching for regularized equilibria of signaling game. Across several datasets capturing real and idealized human judgments about pragmatic implicatures, ReCo matches or improves upon predictions made by best response and rational speech act models of language understanding

Multitasking Inhibits Semantic Drift
Athul Paul Jacob,
Mike Lewis,
Jacob Andreas
North American Chapter of the Association for Computational Linguistics (NAACL), 2021   (Oral Presentation)
We prove that multitask training eliminates semantic drift in a well-studied family of signaling games, and show that multitask training of neural latent language policies (LLPs) in a complex strategy game reduces drift and while improving sample efficiency.

Learning Hierarchical Structures On-The-Fly with a Recurrent-Recursive Model for Sequences
Athul Paul Jacob*,
Zhouhan Lin*,
Alessandro Sordoni,
Yoshua Bengio
Association for Computational Linguistics (ACL), 2018
A hierarchical model for sequential data that learns a tree on-the-fly. The model adapts its structure and reuses recurrent weights in a recursive manner by creating adaptive skip-connections that ease the learning of long-term dependencies.
