Position Weight Matrices (PWMs). Position Weight Matrices
, 2009
"... Position Weight Matrices (PWMs) are broadly used in computational biology. The basic problem, SCAN, aims to find the occurrences of a given PWM in large sequences. Some other PWM tasks share a common NPhard subproblem, SCOREDISTRIBUTION. The existing algorithms rely on the enumeration on a large se ..."

Threshold for Positional Weight Matrix
"... Abstract—In biological sequence research, the positional weight matrix (PWM) is often used to search for putative transcription factor binding sites. A set of experimentally verified oligonucleotides known to be functional motifs are collected and aligned. The frequency of each nucleotide A, C, G, o ..."

Positional weight constraints in OT
"... Certain prosodic positions such as wordinitial syllables and the root are inherently stronger than others. The strength of these positions is manifested in several ways, including, among others, the attraction of stress (see, for example, Hyman 1977 on initial ..."

The CrossSection of Positively Weighted Portfolios
, 2007
"... This paper examines properties of meanvariance inefficient proxies with respect to producing a linear relation between expected returns and betas. The numerical results of a Monte Carlo simulation show that in the CAPM slightly inefficient, positively weighted proxies cause an almost perfect linear ..."

Image denoising using a scale mixture of Gaussians in the wavelet domain
 IEEE TRANS IMAGE PROCESSING
, 2003
"... We describe a method for removing noise from digital images, based on a statistical model of the coefficients of an overcomplete multiscale oriented basis. Neighborhoods of coefficients at adjacent positions and scales are modeled as the product of two independent random variables: a Gaussian vecto ..."

Robust principal component analysis?
 Journal of the ACM,
, 2011
"... Abstract This paper is about a curious phenomenon. Suppose we have a data matrix, which is the superposition of a lowrank component and a sparse component. Can we recover each component individually? We prove that under some suitable assumptions, it is possible to recover both the lowrank and the ..."

rank and the sparse components exactly by solving a very convenient convex program called Principal Component Pursuit; among all feasible decompositions, simply minimize a weighted combination of the nuclear norm and of the 1 norm. This suggests the possibility of a principled approach to robust principal component
Halfa century of research on the Stroop effect: An integrative review
 PsychologicalBulletin
, 1991
"... The literature on interference in the Stroop ColorWord Task, covering over 50 years and some 400 studies, is organized and reviewed. In so doing, a set ofl 8 reliable empirical findings is isolated that must be captured by any successful theory of the Stroop effect. Existing theoretical positions a ..."
