Me and My AI 2: The Bellman Equation and Markov Processes

A set of possible actions A. A real valued reward function R (s,a). A policy the solution of Markov Decision Process. Markov processes are a special class of mathematical models which are often applicable to decision problems. In a Markov process, various states are defined. The probability of going to each of the states depends only on the present state and is independent of how we arrived at that state. Example on Markov Analysis: Markov Models Markov Chain Model Discrete state-space processes characterized by transition matrices Markov-Switching Dynamic Regression Model Discrete-time Markov model containing switching state and dynamic regression State-Space Models Continuous state-space processes characterized by state Markov process, hence the Markov model itself can be described by A and π. 2.1 Markov Model Example In this section an example of a discrete time Markov process will be presented which leads into the main ideas about Markov chains.

We propose a latent topic model with a Markov transition for process data, which consists of time-stamped events recorded in a log file. Such data are becoming more widely available in computer-based educational assessment with complex problem-solving items. The proposed model … 2011-08-26 2015-03-31 Hidden Markov models are useful in simultaneously analyzing a longitudinal observation process and its dynamic transition. Existing hidden Markov models focus on mean regression for the longitudinal response.

Markov process, sequence of possibly dependent random variables ( x1, x2, x3, …)—identified by increasing values of a parameter, commonly time—with the property that any prediction of the next value of the sequence ( xn ), knowing the preceding states ( x1, x2, …, xn − 1 ), may be based on the last state ( xn − 1) alone. MARKOV PROCESSES 5 A consequence of Kolmogorov’s extension theorem is that if {µS: S ⊂ T ﬁnite} are probability measures satisfying the consistency relation (1.2), then there exist random variables (Xt)t∈T deﬁned on some probability space (Ω,F,P) such that L((Xt)t∈S) = µS for each ﬁnite S ⊂ T. (The canonical choice is Ω = Q t∈T Et.)

Almost all RL problems can be modeled as an MDP. MDPs are widely used for solving various optimization problems.
