Generalization Bounds via Information Density and Conditional Information Density [PDF]
, 2020 We present a general approach, based on an exponential inequality, to derive bounds on the generalization error of randomized learning algorithms. Using this approach, we provide bounds on the average generalization error as well as bounds on its tail ...

On the density dependence of the mean density approximation [PDF]
Journal of Physics F: Metal Physics, 1985 The density dependence of the effective pair potential has been used to obtain generalisations of the mean density approximation for liquid structure factors at long wavelengths.

Exploration, normalization, and summaries of high density oligonucleotide array probe level data.
Biostatistics, 2003 In this paper we report exploratory analyses of high-density oligonucleotide array data from the Affymetrix GeneChip system with the objective of improving upon currently used measures of gene expression. Our analyses make use of three data sets: a small

Loop corrections in spin models through density consistency [PDF]
, 2019 Computing marginal distributions of discrete or semidiscrete Markov random fields (MRFs) is a fundamental, generally intractable problem with a vast number of applications in virtually all fields of science.

The local density approximation in density functional theory [PDF]
Pure and Applied Analysis, 2020 We give the first mathematically rigorous justification of the Local Density Approximation in Density Functional Theory. We provide a quantitative estimate on the difference between the grand-canonical Levy-Lieb energy of a given density (the lowest possible energy of all quantum states having this density) and the integral over the Uniform Electron ...
