Meyer", "Eric B. Laber", "Robert Brigantic" ], "categories": [ "cs.LG", "stat.ML" ], "abstract": "Pursuit-evasion is a multi-agent sequential decision problem wherein a group of agents known as pursuers coordinate their traversal of a spatial domain to locate an agent trying to evade them. Pursuit evasion problems arise in a number of import application domains including defense and route planning. Learning to optimally coordinate pursuer behaviors so as to minimize time to capture of the evader is challenging because of a large action space and sparse noisy state information; consequently, previous approaches have relied primarily on heuristics. We propose a variant of Thompson Sampling for pursuit-evasion that allows for the application of existing model-based planning algorithms. This approach is general in that it allows for an arbitrary number of pursuers, a general spatial domain, and the integration of auxiliary information provided by informants. In a suite of simulation experiments, Thompson Sampling for pursuit evasion significantly reduces time-to-capture relative to competing algorithms.", "revisions": [ { "version": "v1", "updated": "2018-11-11T20:17:01.000Z" } ], "analyses": { "keywords": [ "thompson sampling", "pursuit-evasion problems", "significantly reduces time-to-capture relative", "multi-agent sequential decision problem", "spatial domain" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
