Spatio-temporal Relational Constraints Calculi
Prof. Debasis Mitra, Department of Computer Sciences, Florida Institute of Technology, Melbourne
Date & Time: December 14, 2007 10:30
Venue: Conference Room, ‘C’ Block, 01st floor, Kanwal Rekhi Building
Spatio-temporal reasoning (STR) is an evolving branch of artificial intelligence with many theoretical and empirical challenges. The problem consists of relational and disjunctive constraints between objects and events involving space and time. In this talk we will provide an overview of some STR calculi developed in the last few decades. Reasoning in most of such calculi is intractable. However, some tractable sub-problems have been identified. I will also briefly discuss the works related to the complexity issues of some of these calculi. The talk will include some of our works on detecting patterns responsible for inconsistency in temporal reasoning systems.
Speaker Profile:
Debasis Mitra is a faculty member at the Florida Institute of Technology. He is a Ph.D. in Physics (Indian Institute of Technology, Kharagpur) and in Computer Science (Center for Advanced Computer Studies, University of Louisiana). Debasis’ contributions within spatio-temporal reasoning include studies of some new calculi and in finding explanation for inconsistency in the interval reasoning problems. Dr. Mitra's work has been initiated by a CAREER award from the National Science Foundation (NSF) of the US. His current projects are on studying creativity using constraint-based knowledge representation (supported by NSF), and on developing algorithms for detecting radioactive contraband using cosmic ray (supported by Department of Homeland Security, USA). Dr. Mitra is also interested in Bio-informatics. In the past he has worked on Mathematical Physics, and has industrial experience in seismic exploration.
