In this paper, a hidden Markov model (HMM)-based dynamic sensor scheduling problem is formulated, and solved using information gain and rollout concepts to overcome the computational intractability of the dynamic programming recursion. The problem involves dynamically sequencing a set of sensors to monitor multiples tasks, which are modeled as multiple HMMs(More)
— Piracy on the high seas is a problem of worldwide concern. In response to this threat, the US Navy has developed a visualization tool known as the Pirate Attack Risk Surface (PARS) that integrates intelligence data, commercial shipping routes, and meteorological and oceanographic (METOC) information to predict regions where pirates may be present and(More)
— In this paper, a hidden Markov model (HMM)-based dynamic sensor scheduling problem is formulated, and solved using rollout concepts to overcome the computational intractability of the dynamic programming (DP) recursion. The problem considered here involves dynamically sequencing a set of sensors to minimize the sum of sensor cost and the HMM state(More)
