title: Improved Structural Discovery and Representation Learning of Multi-Agent Data
abstract: Central to all machine learning algorithms is data representation. For multi-agent systems, selecting a representation which adequately captures the interactions among agents is challenging due to the latent group structure which tends to vary depending on various contexts. However, in multi-agent systems with strong group structure, we can simultaneously learn this structure and map a set of agents to a consistently ordered representation for further learning. In this paper, we present a dynamic alignment method which provides a robust ordering of structured multi-agent data which allows for representation learning to occur in a fraction of the time of previous methods.  We demonstrate the value of this approach using a large amount of soccer tracking data from a professional league.
