The new model is an extension of the existing Abstract Hidden Markov Model to allow the policy to have internal memory which can be updated in a Markov fashion. We show that the AHMEM can represent a richer class of probabilistic plans, and at the same time derive an efficient algorithm for plan recognition in the AHMEM based on the RaoBiackwellised Particle Filter approximate inference method.","doi":null,"url":"https://ijcai.org/proceedings/2003/186","pdf":"https://ijcai.org/proceedings/2003/0186.pdf","markdown":"https://ijcai.org/proceedings/2003/186.md","bibtex":"https://ijcai.org/proceedings/2003/bibtex/186","volume":{"slug":"2003","title":"Proceedings of the Eighteenth International Joint Conference on Artificial Intelligence","short_title":"IJCAI 2003","url":"https://ijcai.org/proceedings/2003/","year":2003,"location":"Acapulco, Mexico","dates":"","editors":"Georg Gottlob","isbn":"","publisher":"International Joint Conferences on Artificial Intelligence","doi_prefix":""},"section":null,"track":"","number":186,"pages":{"first":1309,"last":1317},"keywords":[],"videos":[],"references":[],"license_note":"Copyright International Joint Conferences on Artificial Intelligence."}
