Webbversus algorithmic sufficient statistic (related to lossy compression in the Shannon theory versus mean-ingful information in the Kolmogorov theory), and rate distortion theory versus Kolmogorov’s structure function. Part of the material has appeared in print before, scattered through various publications, but Webb1 okt. 2015 · This results in an expression for the minimal possible distortion achievable under any analog-to-digital conversion scheme involving uniform sampling and linear filtering. These results thus unify the Shannon-Whittaker-Kotelnikov sampling theorem and Shannon rate-distortion theory for Gaussian sources.
