Instead, these bounds depend only on a certain horizon time of the process and logarithmically on the number of actions. Complexity Issues in Markov Decision Processes by Judy Goldsmith, Martin Mundhenk - In Proc. IEEE conference on Computational Complexity , 1998
This thesis presents a new method based on Markov chain Monte Carlo (MCMC) algorithm to effectively compute the probability of a rare event. The conditional distri- bution of the underlying process given that the rare event occurs has the probability of the rare event as its normalising constant.
MDPs are useful for studying optimization problems solved via dynamic programming. MDPs were known at least as early as the 1950s; a core body of research on Markov decision processes resulted from Ronald Howard's 1960 book, Dynamic En Markovprocess, uppkallad efter den ryske matematikern Markov, är inom matematiken en tidskontinuerlig stokastisk process med Markovegenskapen, det vill säga att processens förlopp kan bestämmas utifrån dess befintliga tillstånd utan kännedom om det förflutna. The previous chapter dealt with the discrete-time Markov decision model. In this model, decisions can be made only at fixed epochs t = 0, 1, . . . .

We illustrate these ideas with an example. I also introduce the idea of a regular Markov chain, but do not discuss EP2200 Queuing theory and teletraffic systems.

{agopal,engwall}@kth.se ABSTRACT We propose a unified framework to recover articulation from a u-diovisual speech. The nonlinear audiovisual-to-articulatory map-ping is modeled by means of a switching linear dynamical system. Switching is governed by a state sequence determined via a Hid-den Markov Model alignment process.

The aggregation utilizes total variation distance as a measure of discriminating the Markov process by the aggregate process, and aims to maximize the entropy of the aggregate process invariant probability, subject to a fidelity described by the total variation Place: All meetings take place in room 3733, Department of Mathematics, KTH, Lindstedtsväg 25, floor 7. Examination: Assignments. Course description: A reading course based on the book "Markov Chains" by J. R. Norris. To each meeting you should solve at least two problem per section from the current chapter, write down the solutions and bring We provide novel methods for the selection of the order of the Markov process that are based upon only the structure of the extreme events. Under this new framework, the observed daily maximum temperatures at Orleans, in central France, are found to be well modelled by an asymptotically independent third-order extremal Markov model.
