Relational Forward Models for Multi-Agent Learning
This addresses the need for analysis tools and faster learning in multi-agent systems, which is crucial for autonomous systems and coordination with humans, though it appears incremental as it builds on existing relational modeling approaches.
The paper tackles the problem of predicting agent behavior in multi-agent systems by introducing Relational Forward Models (RFM), which learn to make accurate predictions and produce interpretable representations, resulting in faster learning systems compared to baselines.
The behavioral dynamics of multi-agent systems have a rich and orderly structure, which can be leveraged to understand these systems, and to improve how artificial agents learn to operate in them. Here we introduce Relational Forward Models (RFM) for multi-agent learning, networks that can learn to make accurate predictions of agents' future behavior in multi-agent environments. Because these models operate on the discrete entities and relations present in the environment, they produce interpretable intermediate representations which offer insights into what drives agents' behavior, and what events mediate the intensity and valence of social interactions. Furthermore, we show that embedding RFM modules inside agents results in faster learning systems compared to non-augmented baselines. As more and more of the autonomous systems we develop and interact with become multi-agent in nature, developing richer analysis tools for characterizing how and why agents make decisions is increasingly necessary. Moreover, developing artificial agents that quickly and safely learn to coordinate with one another, and with humans in shared environments, is crucial.
