Near optimal lossy source coding and compression-based denoising via Markov chain Monte Carlo

Shirin Jalali, Tsachy Weissman
2008 2008 42nd Annual Conference on Information Sciences and Systems  
We also show how our approach carries over to such problems as universal Wyner-Ziv coding and compression-based denoising.  ...  We propose an implementable new universal lossy source coding algorithm.  ...  Our algorithm borrows two well-known tools from statistical physics and computer science, namely Markov Chain Monte Carlo (MCMC) methods, and simulated annealing [10] , [11] .  ...

Statistical Physics and Information Theory Perspectives on Linear Inverse Problems [article]

Junan Zhu
2017 arXiv   pre-print
Both SMV and MMV are linear models (LM's), and the process of estimating the underlying vector(s) x from an LM given the matrices, noisy measurements, and knowledge of the noise statistics, is called a  ...  The intuition of the application of statistical physics to our problem is that statistical physics deals with large-scale problems, and we can make an analogy between an LM and a thermodynamic system.  ...  Markov chain Monte Carlo Having approximated the coding length, we now describe how to optimize our objective function.  ...
