On the role of population heterogeneity in emergent communication

Mathieu Rita, Florian Strub, Jean-Bastien Grill +2

Populations have often been perceived as a structuring component for language to emerge and evolve: the larger the population, the more structured the language. While this observat…

ARE: Scaling Up Agent Environments and Evaluations

Romain Froger, Pierre Andrews, Matteo Bettini +21

We introduce Meta Agents Research Environments (ARE), a research platform for scalable creation of environments, integration of synthetic or real applications, and execution of age…

Countering Reward Over-optimization in LLM with Demonstration-Guided Reinforcement Learning

Mathieu Rita, Florian Strub, Rahma Chaabouni +3

While Reinforcement Learning (RL) has been proven essential for tuning large language models (LLMs), it can lead to reward over-optimization (ROO). Existing approaches address ROO…

Language Evolution with Deep Learning

Mathieu Rita, Paul Michel, Rahma Chaabouni +3

Computational modeling plays an essential role in the study of language emergence. It aims to simulate the conditions and learning processes that could trigger the emergence of a s…

The Llama 3 Herd of Models

Aaron Grattafiori, Abhimanyu Dubey, Abhinav Jauhri +556

Modern artificial intelligence (AI) systems are powered by foundation models. This paper presents a new set of foundation models, called Llama 3. It is a herd of language models th…

On the Correspondence between Compositionality and Imitation in Emergent Neural Communication

Emily Cheng, Mathieu Rita, Thierry Poibeau

Compositionality is a hallmark of human language that not only enables linguistic generalization, but also potentially facilitates acquisition. When simulating language emergence w…

Gaia2: Benchmarking LLM Agents on Dynamic and Asynchronous Environments

Romain Froger, Pierre Andrews, Matteo Bettini +21

We introduce Gaia2, a benchmark for evaluating large language model agents in realistic, asynchronous environments. Unlike prior static or synchronous evaluations, Gaia2 introduces…

Emergent Communication: Generalization and Overfitting in Lewis Games

Mathieu Rita, Corentin Tallec, Paul Michel +4

Lewis signaling games are a class of simple communication games for simulating the emergence of language. In these games, two agents must agree on a communication protocol in order…

"LazImpa": Lazy and Impatient neural agents learn to communicate efficiently

Mathieu Rita, Rahma Chaabouni, Emmanuel Dupoux

Previous work has shown that artificial neural agents naturally develop surprisingly non-efficient codes. This is illustrated by the fact that in a referential game involving a spe…
