Algorithms for Nonnegative Matrix Factorization
 In NIPS
, 2001
"... Nonnegative matrix factorization (NMF) has previously been shown to be a useful decomposition for multivariate data. Two different multiplicative algorithms for NMF are analyzed. They differ only slightly in the multiplicative factor used in the update rules. One algorithm can be shown to minim ..."

Color Constancy: Generalized Diagonal Transforms Suffice
 J. Opt. Soc. Am. A
, 1994
"... This study's main result is to show that under the conditions imposed by the MaloneyWandell color constancy algorithm, whereby illuminants are three dimensional and reflectances two dimensional (the 32 world), color constancy can be expressed in terms of a simple independent adjustment of the ..."

of the sensor responses (in other words, as a von Kries adaptation type of coefficient rule algorithm) as long as the sensor space is first transformed to a new basis. A consequence of this result is that any color constancy algorithm that makes 32 assumptions, such as the MaloneyWandell subspace algorithm
Diagonal Cumulation of Rules of Origin in South America
"... SUMMARY This paper provides a description of what Rules of Origin are, its economic effects, the main RoO types and the options for adding leniency to these rules by means of using the diagonal cumulation. Nowadays, cumulation of origin is studied in different trade agreements models in the Americas ..."

CHAPTER 2 DIAGONAL CORRESPONDENCE THEORY
"... In chapter one I highlighted a number of observations for harmony and tonal interactions that are opaque. First, I argued that opacity is better defined as inputdefined output, as contrasted with transparent, outputdefined output. Second, I argued that the generalization captured by ordered alpha ..."

An Analysis of Diagonal and Nondiagonal QCD Sum Rules for Heavy Baryons at NexttoLeading Order in αS
, 1997
"... We consider diagonal and nondiagonal QCD sum rules for the ground state heavy baryons to leading order in 1/mQ and at nexttoleading order in αS. In the nondiagonal case we evaluate the eight different twoloop diagrams which determine the perturbative αScorrections to the Wilson coefficient of ..."

Coil sensitivity encoding for fast MRI. In:
 Proceedings of the ISMRM 6th Annual Meeting,
, 1998
"... New theoretical and practical concepts are presented for considerably enhancing the performance of magnetic resonance imaging (MRI) by means of arrays of multiple receiver coils. Sensitivity encoding (SENSE) is based on the fact that receiver sensitivity generally has an encoding effect complementa ..."

of aliasing plays an important role with respect to SNR. As a rule of thumb it can be said that local SNR improves when the degree of aliasing is reduced. Therefore it is beneficial to exclude a pixel from reconstruction when the corresponding volume contributes no signal, e.g., because it lies outside
Biascorrected diagonal discriminant rules for highdimensional classification
 Biometrics
, 2010
"... Summary. Diagonal discriminant rules have been successfully used for highdimensional classification problems, but suffer from the serious drawback of biased discriminant scores. In this article, we propose improved diagonal discriminant rules with biascorrected discriminant scores for highdimensi ..."

Offdiagonal Interactions, Hund’s Rules and Pairbinding in Hubbard Molecules
, 1994
"... We have studied the effect of including nearestneighbor, electronelectron interactions, in particular the offdiagonal (non densitydensity) terms, on the spectra of truncated tetrahedral and icosahedral “Hubbard molecules,” focusing on the relevance of these systems to the physics of doped C60. O ..."

Performance Bounds And Design Rules For Product Codes With HyperDiagonal Parity
, 2000
"... In this work, we present results on the minimum distance and minimum distance multiplicity of two and three dimensional "hyperproduct codes" (HPCs), consisting of a concatenation of product block codes followed by an extra parity computation along the hyperdiagonal. Constituent block co ..."

codes considered include simple parity codes and extended Hamming codes. The hyperdiagonal parity can increase d min by over 50%, with relatively small loss in code rate, and is easily implemented in with an inplace computation. By using a binomial approximation on the multiplicities of higher weight
