How Is Markov Chain Calculated?

Definition. The Markov chain X(t) is time-homogeneous if P(Xn+1 = j|Xn = i) = P(X1 = j|X0 = i), i.e. the transition probabilities do not depend on time n. If this is the case, we write pij = P(X1 = j|X0 = i) for the probability to go from i to j in one step, and P = (pij) for the transition matrix.

How is Markov chain entropy calculated?

Theorem: For a stationary time-invariant Markov process. the entropy rate is given by H(X) = H(X2|X1) where the conditional entropy is calculated using the stationary distribution.

How do Markov chains work?

A Markov chain is a mathematical system that experiences transitions from one state to another according to certain probabilistic rules. The defining characteristic of a Markov chain is that no matter how the process arrived at its present state, the possible future states are fixed.
