Web2.3 Gibbs Sampling Gibbs Sampling is an important special case of Metropolis-Hastings algorithm with conditional distribution as proposal distribution q(·) and the acceptance rate 1. Algorithm details can be found in algorithm 2. In algorithm 2, the inner loop can be viewed as the composition of K (the number of dimensions) Webenergy values could be turned into a probability density p(x) through the Gibbs distribution: p(yjx) = e E(x;y)=T R y0 e E(x;y0)=T = e e E(x)=T; (1) where the denominator R y0 e E(x;y0)=T is called the partition function, which marginalizes over y, and Tis the temperature parameter.

WebSampling from the Gibbs distribution is inherently tied to estimating the partition function. Markov properties that simplify the distribution also decompose the computation of the partition function. 2.

WebEquation (6.9) is just a Gibbs distribution. At zero temperature (β = ∞), this is a delta function at the minimal energy state, as derived in the above analysis of the deterministic case. As temperature increases, it becomes an increasingly wide distribution, still peaked at the minimal energy state. The Boltzmann distribution appears in statistical mechanics when considering closed systems of fixed composition that are in thermal equilibrium (equilibrium with respect to energy exchange). The most general case is the probability distribution for the canonical ensemble.
