Available in PDF, EPUB and Kindle. Book excerpt: The subject of this thesis is the analysis of Markov Chain Monte Carlo (MCMC) methods and the development of new methodologies to sample from a high dimensional distribution. Our work is divided into three main topics. The first problem addressed in this manuscript is the convergence of Markov chains in Wasserstein distance. Geometric and sub-geometric convergence with explicit constants, are derived under appropriate conditions. These results are then applied to thestudy of MCMC algorithms. The first analyzed algorithm is an alternative scheme to the Metropolis Adjusted Langevin algorithm for which explicit geometric convergence bounds are established. The second method is the pre-Conditioned Crank-Nicolson algorithm. It is shown that under mild assumption, the Markov chain associated with thisalgorithm is sub-geometrically ergodic in an appropriated Wasserstein distance. The second topic of this thesis is the study of the Unadjusted Langevin algorithm (ULA). We are first interested in explicit convergence bounds in total variation under different kinds of assumption on the potential associated with the target distribution. In particular, we pay attention to the dependence of the algorithm on the dimension of the state space. The case of fixed step sizes as well as the case of nonincreasing sequences of step sizes are dealt with. When the target density is strongly log-concave, explicit bounds in Wasserstein distance are established. These results are then used to derived new bounds in the total variation distance which improve the one previously derived under weaker conditions on the target density.The last part tackles new optimal scaling results for Metropolis-Hastings type algorithms. First, we extend the pioneer result on the optimal scaling of the random walk Metropolis algorithm to target densities which are differentiable in Lp mean for p ≥ 2. Then, we derive new Metropolis-Hastings type algorithms which have a better optimal scaling compared the MALA algorithm. Finally, the stability and the convergence in total variation of these new algorithms are studied.

Available in PDF, EPUB and Kindle. Book excerpt: This dissertation contains three methods aiming at improving the scalability of Markov Chain Monte Carlo (MCMC) sampling. The first method addresses the computation bottleneck of Metropolis-Hastings in Bayesian models with a large number of observations. As an extension to the first method, we have developed a new MCMC algorithm to handle multimodal high-dimensional posterior distributions with a large number of observations. Our objective with the third method is to improve the efficiency of MH in high dimension, by designing a novel local MH move to make an effective use of the gradient information of the log target density. In the first part, we propose a general framework of performing MCMC with only a mini-batch of data. We show that by estimating the MH ratio with only a subset of data, one can sample from the true posterior raised to a known temperature. We show by experiments that our algorithm, ``Mini-batch Tempered MCMC'', can efficiently explore the landscape of a multimodal posterior distribution. In addition, based on the Equi-Energy sampler \citep{kou2006discussion}, we propose a new MCMC algorithm, which enables exact sampling from high-dimensional multimodal posteriors with well-separated modes. In the second part, we introduce a novel local MH move which we shall refer to as the ``Cone Move''. Our goal is to address a crucial limitation of Langevin Dynamics, namely its inherent inefficiency in utilizing the gradient information in exploring the target distribution. Compared with Langevin Dynamics, Cone Move makes better use of the gradient information and thus generates more targeted moves along the shape of the target distribution. We propose a new MCMC algorithm, the Cone Sampler, which adapts to the geometry of the target density by alternating between Cone Move and Langevin Dynamics. We demonstrate the effectiveness of Cone Sampler by testing its performance on challenging sampling problems in high dimensions.

Book excerpt: In this paper, we consider, both computationally and theoretically, the properties of adaptive Markov Chain Monte Carlo (a-MCMC) methods. We begin our study with a famous MCMC realization, the Metropolis-Hastings algorithm. We further apply this algorithm to evaluate high-dimensional integrals. We also extend the algorithms to the case of adaptive MCMC methods and prove several results related to its basic properties, such as ergodicity and aperiodicity. We also plan to focus our efforts also on showing that a-MCMC methods are advantageous over the standard (non-adaptive) MCMC methods.

Download or read book Particle Markov Chain Monte Carlo written by and published by . This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Markov chain Monte Carlo (MCMC) and sequential Monte Carlo (SMC) methods have emerged as the two main tools to sample from high-dimensional probability distributions. Although asymptotic convergence of MCMC algorithms is ensured under weak assumptions, the performance of these latters is unreliable when the proposal distributions used to explore the space are poorly chosen and/or if highly correlated variables are updated independently. In this thesis we propose a new Monte Carlo framework in which we build efficient high-dimensional proposal distributions using SMC methods. This allows us to design effective MCMC algorithms in complex scenarios where standard strategies fail. We demonstrate these algorithms on a number of example problems, including simulated tempering, nonlinear non-Gaussian state-space model, and protein folding.
