Measuring and Mitigating Solution Mode Collapse in RLVR

Liv G. d'Aliberti, Marwa Abdulhai, Sofiia Druchyna +2

A language model (LM) can usually answer the same question in more than one way, but reinforcement learning with verifiable rewards (RLVR) is indifferent to which correct answer a…

One Frozen Simulator Is Not Enough: Simulator Collapse in Multi-Agent RL

Simon Yu, Nicholas Tomlin, Marwa Abdulhai +7

Multi-agent reinforcement learning for human-AI interaction typically relies on a single large language model to simulate user behavior. We show that this approach systematically f…

Evaluating Generalization Capabilities of LLM-Based Agents in Mixed-Motive Scenarios Using Concordia

Chandler Smith, Marwa Abdulhai, Manfred Diaz +83

Large Language Model (LLM) agents have demonstrated impressive capabilities for social interaction and are increasingly being deployed in situations where they might engage with bo…

Consistently Simulating Human Personas with Multi-Turn Reinforcement Learning

Marwa Abdulhai, Ryan Cheng, Donovan Clay +3

Large Language Models (LLMs) are increasingly used to simulate human users in interactive settings such as therapy, education, and social role-play. While these simulations enable…

Evaluating & Reducing Deceptive Dialogue From Language Models with Multi-turn RL

Marwa Abdulhai, Ryan Cheng, Aryansh Shrivastava +3

Large Language Models (LLMs) interact with millions of people worldwide in applications such as customer support, education and healthcare. However, their ability to produce decept…

Enhancing Personalized Multi-Turn Dialogue with Curiosity Reward

Yanming Wan, Jiaxing Wu, Marwa Abdulhai +2

Effective conversational agents like large language models (LLMs) must personalize their interactions to adapt to user preferences, personalities, and attributes across diverse dom…

LMRL Gym: Benchmarks for Multi-Turn Reinforcement Learning with Language Models

Marwa Abdulhai, Isadora White, Charlie Snell +5

Large language models (LLMs) provide excellent text-generation capabilities, but standard prompting and generation methods generally do not lead to intentional or goal-directed age…

Moral Foundations of Large Language Models

Marwa Abdulhai, Gregory Serapio-Garcia, Clément Crepy +3

Moral foundations theory (MFT) is a psychological assessment tool that decomposes human moral reasoning into five factors, including care/harm, liberty/oppression, and sanctity/deg…

Personality Traits in Large Language Models

Greg Serapio-García, Mustafa Safdari, Clément Crepy +6

The advent of large language models (LLMs) has revolutionized natural language processing, enabling the generation of coherent and contextually relevant human-like text. As LLMs in…

Basis for Intentions: Efficient Inverse Reinforcement Learning using Past Experience

Marwa Abdulhai, Natasha Jaques, Sergey Levine

This paper addresses the problem of inverse reinforcement learning (IRL) -- inferring the reward function of an agent from observing its behavior. IRL can provide a generalizable a…

Context-Specific Representation Abstraction for Deep Option Learning

Marwa Abdulhai, Dong-Ki Kim, Matthew Riemer +3

Hierarchical reinforcement learning has focused on discovering temporally extended actions, such as options, that can provide benefits in problems requiring extensive exploration.…

A Policy Gradient Algorithm for Learning to Learn in Multiagent Reinforcement Learning

Dong-Ki Kim, Miao Liu, Matthew Riemer +6

A fundamental challenge in multiagent reinforcement learning is to learn beneficial behaviors in a shared environment with other simultaneously learning agents. In particular, each…
