Analysis of a Class of Multilevel Markov Chain Monte Carlo Algorithms Based on Independent Metropolis–Hastings

Fabio Nobile, Juan Pablo Madrigal Cianci

In this work, we present, analyze, and implement a class of multilevel Markov chain Monte Carlo(ML-MCMC) algorithms based on independent Metropolis--Hastings proposals for Bayesian inverse problems. In this context, the likelihood function involves solving ...

HIERARCHICAL MARKOV CHAIN MONTE CARLO METHODS FOR BAYESIAN INVERSE PROBLEMS

Juan Pablo Madrigal Cianci

This thesis is devoted to the construction, analysis, and implementation of two types of hierarchical Markov Chain Monte Carlo (MCMC) methods for the solution of large-scale Bayesian Inverse Problems (BIP). The first hierarchical method we present is base ...

Approaching the Rate-Distortion Limit With Spatial Coupling, Belief Propagation, and Decimation

Nicolas Macris, Marc Vuffray, Vahid Aref

We investigate an encoding scheme for lossy compression of a binary symmetric source based on simple spatially coupled low-density generator-matrix codes. The degree of the check nodes is regular and the one of code-bits is Poisson distributed with an aver ...

Automatic Role Recognition in Multiparty Conversations: an Approach Based on Turn Organization, Prosody and Conditional Random Fields

Alessandro Vinciarelli

Roles are a key aspect of social interactions, as they contribute to the overall predictability of social behavior (a necessary requirement to deal effectively with the people around us), and they result in stable, possibly machine-detectable behavioral pa ...

Interplay of electronic correlations and lattice instabilities in BaVS3

Helmuth Berger

The quasi-one-dimensional metallic system BaVS3 with a metal-insulator transition at T-MI=70 K shows large changes in the optical phonon spectrum, a central peak, and an electronic Raman scattering continuum that evolve in a three-step process. Motivated b ...

Experimental and theoretical investigations of the thermodynamic stability of Ba-C-60 and K-C-60 compound clusters

Klaus Kern

A novel experimental set-up was used to study superstable (magic) Ba-C-60 and K-C-60 compound clusters. The most stable systems observed cannot be rationalized by simple electronic or by geometrical shell filling arguments. Annealing the clusters past the ...

Why Are Ionic Liquids Liquid? A Simple Explanation Based on Lattice and Solvation Energies

Paul Joseph Dyson, Corinne Daguenet

We have developed a simple and quant. explanation for the relatively low melting temps. of ionic liqs. (ILs). The basic concept was to assess the Gibbs free energy of fusion (ΔfusG) for the process IL(s) -> IL(l), which relates to the m.p. ...
