• Authors: Claude Formanek, Asad Jeewa, Jonathan Shock, Arnu Pretorius
• Abstract summary: offline multi-agent reinforcement learning (MARL) provides a promising paradigm for building effective decentralised controllers from such datasets. MARL is still in its infancy and therefore lacks standardised benchmark datasets and baselines. OG-MARL is a growing repository of high-quality datasets with baselines for cooperative offline MARL research.

• Abstract: Being able to harness the power of large datasets for developing cooperative multi-agent controllers promises to unlock enormous value for real-world applications. Many important industrial systems are multi-agent in nature and are difficult to model using bespoke simulators. However, in industry, distributed processes can often be recorded during operation, and large quantities of demonstrative data stored. Offline multi-agent reinforcement learning (MARL) provides a promising paradigm for building effective decentralised controllers from such datasets. However, offline MARL is still in its infancy and therefore lacks standardised benchmark datasets and baselines typically found in more mature subfields of reinforcement learning (RL). These deficiencies make it difficult for the community to sensibly measure progress. In this work, we aim to fill this gap by releasing off-the-grid MARL (OG-MARL): a growing repository of high-quality datasets with baselines for cooperative offline MARL research. Our datasets provide settings that are characteristic of real-world systems, including complex environment dynamics, heterogeneous agents, non-stationarity, many agents, partial observability, suboptimality, sparse rewards and demonstrated coordination. For each setting, we provide a range of different dataset types (e.g. Good, Medium, Poor, and Replay) and profile the composition of experiences for each dataset. We hope that OG-MARL will serve the community as a reliable source of datasets and help drive progress, while also providing an accessible entry point for researchers new to the field.

  offline reinforcement learning (RL) has garnered significant attention for its ability to learn effective policies from pre-collected datasets. MARL presents additional challenges due to the large joint state-action space and the complexity of multi-agent behaviors. We introduce a regularizer in the space of stationary distributions to better handle distributional shift.

  offline multi-agent reinforcement learning (MARL) is an exciting direction of research that uses static datasets to find optimal control policies for multi-agent systems. Though the field is by definition data-driven, efforts have thus far neglected data in their drive to achieve state-of-the-art results. We show how the majority of works generate their own datasets without consistent methodology and provide sparse information about the characteristics of these datasets.

The proposed benchmark can also serve as a testbed for measuring the capability of LLMs in problem discovery rather than just problem-solving.

  We propose a novel model-based MARL algorithm, MABL, that learns a bi-level latent-variable world model from high-dimensional inputs. For each agent, MABL learns a global latent state at the upper level, which is used to inform the learning of an agent latent state at the lower level. MaBL surpasses SOTA multi-agent latent-variable world models in both sample efficiency and overall performance.
