Markov Chain Monte Carlo Method without Detailed Balance

Web6 jul. 2024 · The detailed balance equation should be contrasted with global balance equation below, which all Markov chains with stationary distribution \(\pi\) satisfy. Then it shouldn’t be surprising that global balance equation can be easily derived from detailed balance equation (by summing over \(x'\) on both sides of the above equation) but not … WebKeywords: Reversible Markov chain, detailed balance equations, Kolmogorov criterion Mathematics Subject Classiﬁcation: 60J10, 60J22 Abstract ...

WebA Markov chain is reversible if there exists a distribution Π ∗ which satisfies the detailed balance conditions: ∀i, j , Π ∗ i Pij = Π ∗ j Pji. Theorem: If a distribution Π ∗ is reversible, then Π ∗ is a stationary distribution. Proof: For any state j, we have ∑ iΠ ∗ i Pij = ∑ i Π ∗ j Pji ∑ iΠ ∗ i Pij = Π ∗ j Therefore, Π ∗ P = Π ∗.
