Instead of behavior cloning, what if you asked an LLM to write code to describe how an agent was acting, and used this to predict their future behavior? Our new paper "Modeling Others' Minds as Code" shows this outperforms BC by 2x, and reaches human-level performance in predicting human behavior.

By optimizing for intrinsic curiosity, the LLM learns how to ask a series of questions over the course of the conversation to improve the accuracy of its user model. This generates conversations which reveal significantly more information about the user.

Excited to release our latest paper on a new multi-turn RL objective for training LLMs to *learn how to learn* to adapt to the user. This enables it to adapt and personalize to novel users, whereas the multi-turn RLHF baseline fails to generalize effectively to new users.

This work shows the benefit of RL training for improving reasoning skills when there is no possibility for data leakage. AND how continuously evolving multi-agent competition leads to the development of emergent skills that generalize to novel tasks.

Natasha Jaques @natashajaques.bsky.social · 01/07/2025
We analyze the results and find that LLMs learn emergent reasoning patterns like case-by-case analysis and expected value calculation that transfer to improve performance on math questions.

In our latest paper, we discovered a surprising result: training LLMs with self-play reinforcement learning on zero-sum games (like poker) significantly improves performance on math and reasoning benchmarks, zero-shot. Whaaat? How does this work?

RLHF is the main technique for ensuring LLM safety, but it provides no guarantees that they won’t say something harmful. Instead, we use online adversarial training to achieve theoretical safety guarantees and substantial empirical safety improvements over RLHF, without sacrificing capabilities.

Human-AI cooperation is important, but existing work trains on the same 5 Overcooked layouts, creating brittle strategies. Instead, we find that training on billions of procedurally generated tasks trains agents to learn general cooperative norms that transfer to humans... like avoiding collision

Yes! Or you could focus on developing better MARL algorithms for the corporations that let them cooperate to solve the social dilemma more effectively. Similar to MARL benchmarks like Melting Pot but for a more impactful domain

AI has shown great potential in boosting efficiency. But can it help human society make better decisions as a whole? 🤔 In this project, using MARL, we explore this by studying the impact of an ESG disclosure mandate—a highly controversial policy. (1/6)

Natasha Jaques @natashajaques.bsky.social · 13/02/2025
In contrast, MARL enables testing new policies with many more agents over a long time horizon. We hope this benchmark will enable researchers in the RL and MARL communities to develop sophisticated cooperation algorithms in the context of a societally impactful problem!

Natasha Jaques @natashajaques.bsky.social · 13/02/2025
I’m really excited about this, as I think MARL provides a new tool in the toolbox for investigating this problem. Existing work on ESG disclosures focuses on empirical studies (can’t test counterfactual policies), or analytical economics models (limited to 2 players or short time intervals)

...providing corporations with more reliable information about climate risks — and we show that this significantly improves corporations’ ability to mitigate climate change, even without the influence of investors!

Natasha Jaques @natashajaques.bsky.social · 13/02/2025
The parameters of the environment are carefully benchmarked to real-world data (e.g. from IPCC reports), and many of our experiments reveal findings consistent with empirical work on climate change and ESG disclosures. But we can also test new policy interventions, such as..

Natasha Jaques @natashajaques.bsky.social · 13/02/2025
overall climate risks increase, leading to lower market wealth. By introducing climate-conscious investor agents to simulate the possible effects of ESG disclosures, we show that investors can actually incentivize profit-motivated companies to invest in climate mitigation.

Impressive results that strongly outperform the best classical techniques. Several MARL methods work well, showing the promise of MARL for combinatorial optimization and systems problems, as in our earlier work on MARL for Microprocessor Design arxiv.org/abs/2211.16385 3/3

Natasha Jaques @natashajaques.bsky.social · 02/01/2025
The classical solver can give an optimal, conflict-free assignment for a single timestep if it's given known utility values, but can't plan assignments over time. So, we learn the future estimated payoff for each single-timestep assignment using RL! 2/3

The paper I spoke about at the #NeurIPS2024 ML for Systems workshop is now on arxiv arxiv.org/abs/2412.15573! We use multi-agent RL to solve a classic combinatorial optimization problem (the Sequential Assignment Problem), by combining MARL with a classical polynomial time assignment algorithm. 1/3
