Additive Update Algorithm for Nonnegative Matrix Factorization
Abstract—Nonnegative matrix factorization (NMF) is an emerging technique with a wide spectrum of potential applications in data analysis. Mathematically, NMF can be formulated as a minimization problem with nonnegative constraints. This problem is currently attracting much attention from researchers for theoretical reasons and for potential applications. Currently, the most popular approach to ...
متن کاملAdditive Update Predictors in Active Appearance Models
The Active Appearance Model (AAM) provides an efficient method for localizing objects that vary in both shape and texture, and uses a linear regressor to predict updates to model parameters based on current image residuals. This study investigates using additive (or ‘boosted’) predictors, both linear and non-linear, as a substitute for the linear predictor in order to improve accuracy and effic...
متن کاملSurvival of Listeria monocytogenes in Wilted and Additive-Treated Grass Silage
Grass was field-dried to 3 different dry matter (DM) levels (200, 430 and 540 g/kg) and inoculated with 10(6)-10(7) cfu/g of a Listeria monocytogenes strain sharing a phagovar occasionally involved in foodborne outbreaks of listeriosis. Formic acid (3 ml/kg) or lactic acid bacteria (8 x 10(5)/g) with cellulolytic enzymes were applied only to forages with low and intermediate DM levels. Forages ...
متن کاملShort-Documentation of the Update of the SOEP-Weights, 1984–2008
With the 2008 data, we are distributing a revised version of the SOEP weighting variables from waves 1984 to 2008. The amendments affect the cross-sectional weights (AHHRF-YHHRF) only and not the longitudinal weighting variables (BHLEIB-YHBLEIB). Several developments led to the retroactive update of the cross-sectional weights. First, the SOEP data can now be linked to extensive regional inform...
متن کاملTHE EFFECT OF ECONOMIC EVENTS ON VOTES FOR PRESIDENT: 1984 Update
ln previous work I have developed an equation explaining votes for president in the United States that seems to have remarkable explanatory paver. The purpose of this paper is to update this equation through the 1984 election and then use it to predict the 1988 election. The history of the equation is as follows. The original work was &one in 1976 and published in Fair (1978). In this work I te...
