# markov decision process questions

Questions tagged [markov-decision-process] Ask Question For questions related to Markov decision processes (MDPs), which model decision making in time-varying and usually stochastic environments. The description of a Markov decision process is that it studies a scenario where a system is in some given set of states, and moves forward to another state based on the decisions of a decision maker. Here are some similar questions that might be relevant: If you feel something is missing that should be here, contact us. MDPs are useful for studying optimization problems solved via dynamic programming and reinforcement learning.

He wants to use his knowledge to advise people about presidential candidates. In learning about MDP's I am having trouble with value iteration.Conceptually this example is very simple and makes sense: If you have a 6 sided dice, and you roll a 4 or a 5 or a 6 you keep that amount in $but if you roll a 1 or a 2 or a 3 you loose your bankroll and end the game..

(a) [6] What Specific Task Is Performed By Using The Bellman's Equation In The MDP Solution Process. Questions tagged [markov-decision-process] Ask Question For questions related to the concept of Markov decision process (MDP), which is a mathematical framework for modeling decision making in situations where outcomes are partly random and partly under the control of a decision-maker. In this paper, we study Markov Decision Processes (hereafter MDPs) with arbitrarily varying rewards. Here are the key areas you'll be focusing on: {{courseNav.course.topics.length}} chapters | We assume the Markov Property: the effects of an action taken in a state depend only on that state and not on the prior history. | {{course.flashcardSetCount}} ...
