Combined Density Functional Theory and Monte Carlo Analysis of Monomolecular Cracking of Light Alkanes Over H-ZSM-5

Density functional calculations applying periodic boundary conditions have been performed to investigate adsorption and cracking of light alkanes (C 3-C 6) on zeolite H-ZSM-5. Intrinsic energy barriers were obtained from single-point calculations by applyi ...

Lower and upper bounds for approximation of the Kullback-Leibler divergence between Gaussian Mixture Models

Jean-Philippe Thiran, Finnian Paul Kelly

Many speech technology systems rely on Gaussian Mixture Models (GMMs). The need for a comparison between two GMMs arises in applications such as speaker verification, model selection or parameter estimation. For this purpose, the Kullback-Leibler (KL) dive ...

Comparison-Based Learning with Rank Nets

Amin Karbasi

We consider the problem of search through comparisons, where a user is presented with two candidate objects and reveals which is closer to her intended target. We study adaptive strategies for finding the target, that require knowledge of rank relationship ...

Orthogonality of Two-Dimensional Separations Based on Conditional Entropy

Hubert Girault, Mohammad Reza Pourhaghighi, Mohammad Karzand

A new approach to assess the orthogonality of two-dimensional (2-D) separation systems based on conditional entropy is developed. It considers the quantitative distribution of peaks in the entire separation space such that the orthogonality obtained is ind ...

Experimental charge density of LiBD4 from maximum entropy method

Philippe Mauron

We report on maximum entropy method study of the experimental atomic and ionic charges of LiBD4 in its low-temperature orthorhombic phase. Synchrotron radiation x-ray powder diffraction data, neutron powder diffraction data, and density functional calculat ...

Compression with Graphical Constraints: An Interactive Browser

Amin Karbasi, Morteza Zadimoghaddam

We study the problem of navigating/searching through a database of objects with potentially different popularities using a membership oracle. The membership oracle, given a subset of objects

Image Reconstruction from Compressed Linear Measurements with Side Information

Pascal Frossard, Vijayaraghavan Thirumalai

This paper proposes a joint reconstruction algorithm for compressed correlated images that are given under the form of linear measurements. We consider the particular problem where one image is selected as the reference image and it is used as the side inf ...

Kullback–Leibler Divergence as a Forecast Skill Score with Classic Reliability–Resolution–Uncertainty Decomposition

Steven Vincent Weijs, Nicolaas Cornelis van de Giesen

This paper presents a score that can be used for evaluating probabilistic forecasts of multicategory events. The score is a reinterpretation of the logarithmic score or ignorance score, now formulated as the relative entropy or Kullback–Leibler divergence ...

Why hydrological predictions should be evaluated using information theory

Steven Vincent Weijs, Nicolaas Cornelis van de Giesen

Probabilistic predictions are becoming increasingly popular in hydrology. Equally important are methods to test such predictions, given the topical debate on uncertainty analysis in hydrology. Also in the special case of hydrological forecasting, there is ...

Joint reconstruction of correlated images from compressed linear measurements

Pascal Frossard, Vijayaraghavan Thirumalai

This paper proposes a joint reconstruction algorithm for compressed correlated images that are given under the form of linear measurements. We first propose a geometry based model in order to describe the correlation between visual information in pairs of ...
