Hierarchical dialogue optimization using semi-Markov decision processes [PDF]
Interspeech 2007, 2007 This paper addresses the problem of dialogue optimization on large search spaces. For such a purpose, in this paper we propose to learn dialogue strategies using multiple Semi-Markov Decision Processes and hierarchical reinforcement learning. This approach factorizes state variables and actions in order to learn a hierarchy of policies. Our experiments

Semi-Markov Model of MASS Voyage [PDF]
TransNavThe paper presents the readiness/safety model for the sea voyage of Maritime Autonomous Surface Ship (MASS), based on Semi-Markov process. The states of MASS during the voyage were defined as triplets of intentional type of MASS operations, reliability ...

A survey on semi-Markov decision processes [PDF]
SCIENTIA SINICA Mathematica, 2015 This paper is a survey on semi-Markov decision processes (SMDPs). We present the background, the signi cance, and the research actuality of the in nite horizon expected discounted reward criterion, the long-run expected average reward criterion, the nite horizon expected reward criterion, the expected rst passage reward criterion, the probability ...
