Exact marginals and normalizing constant for Gibbs distributions
We present a recursive algorithm for the calculation of the marginal of a Gibbs distribution π. A direct consequence is the calculation of the normalizing constant of π. Résumé Récurrences et constante de normalisation pour des modèles de Gibbs. Nous proposons dans ce travail une récurrence sur les lois marginales d’une distribution de Gibbs π. Une conséquence directe est le calcul exact de la ...
متن کاملForward recursions and normalizing constant for Gibbs fields
Maximum likelihood parameter estimation is frequently replaced by various techniques because of its intractable normalizing constant. In the same way, the literature displays various alternatives for distributions involving such unreachable constants. In this paper, we consider a Gibbs distribution π and present a recurrence formula allowing a recursive calculus of the marginals of π and in the...
متن کاملPosterior Distributions on Normalizing Constants
This article describes a procedure for deening a posterior distribution on the value of a normalizing constant or ratio of normalizing constants using output from Monte Carlo simulation experiments. The resulting posterior distribution provides a simple diagnostic for assessing the adequacy of a simulation experiment for estimating these quantities, and is particularly useful in cases for which...
متن کاملSampling from Gibbs distributions
Sampling from Gibbs distributions by Eric Joseph Vigoda Doctor of Philosophy in Computer Science University of California at Berkeley Professor Alistair Sinclair, Chair This thesis considers computational questions concerning statistical mechanical models of idealized physical systems. The equilibrium state of the physical system is described by a probability distribution over the allowed con g...
متن کاملQuantum polarization distributions via marginals of quadrature distributions
Polarization is a crucial ingredient of light in both the classical and quantum domains. However, quantum polarization is mainly addressed in terms of the abstract Hilbertspace logic in a finite-dimensional space. This is rather divorced from the usual language used in the classical domain in terms of the Stokes parameters and the Poincaré sphere. Because of this, we think that it is worth deve...
