MATRIX FACTORIZATION TECHNIQUES FOR RECOMMENDER SYSTEMS

by Yehuda Koren, Robert Bell, Chris Volinsky - IEEE COMPUTER , 2009
"... As the Netflix Prize competition has demonstrated, matrix factorization models are superior to classic nearest-neighbor techniques for producing product recommendations, allowing the incorporation of additional information such as implicit feedback, temporal effects, and confidence levels. Modern co ..."

. Therefore, more retailers have become interested in recommender systems, which analyze patterns of user interest in products to provide personalized recommendations that suit a user’s taste. Because good personalized recommendations can add another dimension to the user experience, e-commerce leaders like

gprof: a Call Graph Execution Profiler

by Susan L. Graham, Peter B. Kessler, Marshall K. McKusick , 1982
"... Large complex programs are composed of many small routines that implement abstractions for the routines that call them. To be useful, an execution profiler must attribute execution time in a way that is significant for the logical structure of a program as well as for its textual decomposition. This ..."

Protein homology detection by HMM-HMM comparison

by Johannes Söding - BIOINFORMATICS , 2005
"... Motivation: Protein homology detection and sequence alignment are at the basis of protein structure prediction, function prediction, and evolution. Results: We have generalized the alignment of protein se-quences with a profile hidden Markov model (HMM) to the case of pairwise alignment of profile H ..."

Developments in the Measurement of Subjective Well-Being

by Daniel Kahneman , Alan B Krueger - Psychological Science. , 1993
"... F or good reasons, economists have had a long-standing preference for studying peoples' revealed preferences; that is, looking at individuals' actual choices and decisions rather than their stated intentions or subjective reports of likes and dislikes. Yet people often make choices that b ..."

Prejudice and politics: Symbolic racism versus racial threats to the good life.

by Donald R Kinder , David O Sears - Journal of Personality and Social Psychology, , 1981
"... Although theories of prejudice have been extensively catalogued, empirical confrontations between competing theories are surprisingly rare. The primary goal of the present research was to test two major theoretical approaches to prejudice by whites against blacks: realistic group conflict theory, w ..."

Permanent Scatterers in SAR interferometry

by Ro Ferretti, Claudio Prati, Fabio Rocca - IEEE Transactions on Geosci- ence and Remote Sensing
"... Abstract—Temporal and geometrical decorrelation often pre-vents SAR interferometry from being an operational tool for sur-face deformation monitoring and topographic profile reconstruc-tion. Moreover, atmospheric disturbances can strongly compro-mise the accuracy of the results. In this paper, we pr ..."

Consed: a graphical tool for sequence finishing

by David Gordon , Chris Abajian , Phil Green - Genome Res , 1998
"... Sequencing of large clones or small genomes is generally done by the shotgun approach Although complete automation of data processing in shotgun sequencing is clearly desirable and may be feasible in the near future, at present finishing still requires extensive human intervention. This is customa ..."

. This is customarily done by use of an interactive computer program. The program (which is usually called a sequence editor) must, at a minimum, display the aligned sequences of the assembled reads and allow the user to access underlying raw data (e.g., the fluorescence trace profiles from automated sequencers

Risky families: Family social environments and the mental and physical health of offspring

by Rena L. Repetti, Shelley E. Taylor, Teresa E. Seeman, Rena L. Repetti, Shelley E. Taylor - Psychological Bulletin , 2002
"... Risky families are characterized by conflict and aggression and by relationships that are cold, unsupportive, and neglectful. These family characteristics create vulnerabilities and/or interact with genetically based vulnerabilities in offspring that produce disruptions in psychosocial functioning ( ..."

A Universal Density Profile from Hierarchical Clustering

by Julio F. Navarro, Carlos S. Frenk, Simon D. M. White - The Cluster M-T Relation 6 Temperature Profiles Observed with ASCA and ROSAT. ApJ , 1997
"... We use high-resolution N-body simulations to study the equilibrium density profiles of dark matter halos in hierarchically clustering universes. We find that all such profiles have the same shape, independent of halo mass, of initial density fluctuation spectrum, and of the values of the cosmologica ..."

it was assembled. A suitable definition of this assembly time allows the same proportionality constant to be used for all the cosmologies that we have tested. We compare our results to previous work on halo density profiles and show that there is good agreement. We also provide a step-by-step analytic procedure
