Markov decision process applications

  • Learning Adversarial Markov Decision Processes with Delayed Feedback. 12/29/2020 ∙ by Tal Lancewicki, et al. ∙ 0 ∙ share . Reinforcement learning typically assumes that the agent observes feedback from the environment immediately, but in many real-world applications (like recommendation systems) the feedback is observed in delay.
The reversal Markov chain Pecan be interpreted as the Markov chain Pwith time running backwards. If the chain is reversible, then P= Pe. 3.2 Markov Decision Process A Markov Decision Process (MDP), as defined in [27], consists of a discrete set of states S, a transition function P: SAS7! [0;1], and a reward function r: SA7! R. On each round t,

First, we model the dynamics of threat of an infrastructure as a continuous-time Markov decision process. Several structural results are derived. Furthermore, the model is approximately solved by using an index-based heuristics. Second, we consider discrete-time Markov decision processes. The criterion is to minimize the average value-at-risk for the discounted cost over a finite and over an ...

A Markov decision process is a Markov chain in which state transitions depend on the current state and an action vector that is applied to the system. Markov model - Wikipedia Formally the environment is modeled as a Markov decision process (MDP) with states and actions.
  • 2. Cascade Markov Decision Processes. 2.1. Markov Decision Process Model. We use the framework of [1] for continuous-time nite-state (FSCT) Markov processes. We assume a prob-ability space (;F;P) and right-continuous stochastic processes adapted to a ltration F = (F t) t2T on this space. An FSCT Markov process x t that is assumed to take values ...
  • As a management tool, Markov analysis has been successfully applied to a wide variety of decision situations. Perhaps its widest use is in examining and predicting the behaviour of customers in terms of their brand loyalty and their switching from one brand to another.

Markov decision processes are power-ful analytical tools that have been widely used in many industrial and manufacturing applications such as logistics, finance, and inventory control5 but are not very common in MDM.6 Markov decision processes generalize standard Markov models by embedding the sequential decision process in the

    requests of the application can be either processed locally or sent to the remote server. In the mobile device, the mobile CPU employs DVFS, and the RF transmitter can adaptively select the most appropriate bit rate and modulation scheme for request offloading. We model the mobile device as a semi-Markov decision process (SMDP) [8], in which ...

    The book presents Markov decision processes in action and includes various state-of-the-art applications with a particular view towards finance. It is useful for upper-level undergraduates, Master's students and researchers in both applied probability and finance, and provides exercises (without solutions).

    A Markov Decision Process is a model of a system in which a policy can be learned to maximize reward [6]. It consists of a set of states S, a set of actions A representing possible actions by an agent, a set of transition probabilities indicating how likely it is for the model to transition to each state sʹ ϵ S from each state s ϵ S

    Dec 29, 2020 · Thus, we consider online learning in episodic Markov decision processes (MDPs) with unknown transitions, adversarially changing costs and unrestricted delayed feedback. That is, the costs and trajectory of episode k are only available at the end of episode k + d^k, where the delays d^k are neither identical nor bounded, and are chosen by an ...

    Dec 03, 2018 · This paper explores a class of methods for temporal regularization. We formally characterize the bias induced by this technique using Markov chain concepts. We illustrate the various characteristics of temporal regularization via a sequence of simple discrete and continuous MDPs, and show that the technique provides improvement even in high-dimensional Atari games.

We present an optimization framework for delay-tolerant data applications on mobile phones based on the Markov decision process (MDP). This process maximizes an application specific reward or utility metric, specified by the user, while still meeting a talk-time constraint, under limited resources such as battery life.
