Approximate state estimation in multiagent settings with continuous or large discrete state spaces
Prashant Doshi · 2007
We present a new method for carrying out state estimation in multi-agent settings that are characterized by continuous or large discrete state spaces. State estimation in multiagent settings involves updating an agent's belief over the physical states and the space of other agents' models. We factor out the models of the other agents and update the agent's belief over these models, as exactly as possible. Simultaneously, we sample particles from the distribution over the large physical state space and project the particles in time.
