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

14 years 6 months ago

— We propose an implementable new universal lossy source coding algorithm. The new algorithm utilizes two wellknown tools from statistical physics and computer science: Gibbs sam...
