Accurately interpreting clickthrough data as implicit feedback

by Thorsten Joachims, Laura Granka, Bing Pan, Helene Hembrooke, Geri Gay - In Proceedings of SIGIR , 2005
"... This paper examines the reliability of implicit feedback generated from clickthrough data in WWW search. Analyzing the users ’ decision process using eyetracking and comparing implicit feedback against manual relevance judgments, we conclude that clicks are informative but biased. While this makes t ..."

the interpretation of clicks as absolute relevance judgments difficult, we show that relative preferences derived from clicks are reasonably accurate on average. Categories and Subject Descriptors

Cumulated Gain-based Evaluation of IR Techniques

by Kalervo Järvelin, Jaana Kekäläinen - ACM Transactions on Information Systems , 2002
"... Modem large retrieval environments tend to overwhelm their users by their large output. Since all documents are not of equal relevance to their users, highly relevant documents should be identified and ranked first for presentation to the users. In order to develop IR techniques to this direction, i ..."

methods for their ability to retrieve highly relevant documents and allow testing of statistical significance of effectiveness differences. The graphs based on the measures also provide insight into the performance IR techniques and allow interpretation, e.g., from the user point of ...

Consumers and Their Brands: Developing Relationship Theory

by Susan Fournier - Journal of consumer research , 1998
"... Although the relationship metaphor dominates contemporary marketing thought and practice, surprisingly little empirical work has been conducted on relational phenomena in the consumer products domain, particularly at the level of the brand. In this article, the author: (1) argues for the validity of ..."
Abstract - Cited by 552 (3 self) - Add to MetaCart
of relationships consumers form with brands; and (3) inducts from the data the concept of brand relationship quality, a diagnostic tool for conceptualizing and evaluating relation-ship strength. Three in-depth case studies inform this agenda, their interpretation guided by an integrative review of the literature

The CONSORT statement: revised recommendations for improving the quality of reports of parallel-group randomized trials,”

by MSc; David Moher , PhD, MBA; Kenneth F Schulz , Douglas G Altman - Journal of the American Medical Association, , 1987
"... To comprehend the results of a randomized, controlled trial (RCT), readers must understand its design, conduct, analysis, and interpretation. That goal can be achieved only through complete transparency from authors. Despite several decades of educational efforts, the reporting of RCTs needs improv ..."

A Test of the Efficiency of a Given Portfolio

by R. Gibbons, Tephena Ross, Jay Shanken - In Econometrica , 1989
"... A test for the ex ante efficiency of a given portfolio of assets is analyzed. The relevant statistic has a tractable small sample distribution. Its power function is derived and used to study the sensitivity of the test to the portfolio choice and to the number of assets used to determine the ex pos ..."

Minimax Estimation via Wavelet Shrinkage

by David L. Donoho, Iain M. Johnstone , 1992
"... We attempt to recover an unknown function from noisy, sampled data. Using orthonormal bases of compactly supported wavelets we develop a nonlinear method which works in the wavelet domain by simple nonlinear shrinkage of the empirical wavelet coe cients. The shrinkage can be tuned to be nearly minim ..."

method (kernel, smoothing spline, sieve,:::) in a minimax sense. Variants of our method based on simple threshold nonlinearities are nearly minimax. Our method possesses the interpretation of spatial adaptivity: it reconstructs using a kernel which mayvary in shape and bandwidth from point to point

Context-Based Vision System for Place and Object Recognition

by Antonio Torralba, Kevin P. Murphy, William T. Freeman, Mark Rubin , 2003
"... While navigating in an environment, a vision system has' to be able to recognize where it is' and what the main objects' in the scene are. In this paper we present a context-based vision system for place and object recognition. The goal is' to identify familiar locations' (e ..."
Abstract - Cited by 317 (9 self) - Add to MetaCart

Industrialization and the big push

by Kevin M. Murphy, Andrei Shleifer, Robert W. Vishny, Untuersely U Chlcagu , 1989
"... This paper explores Rosenstein-Rodan's idea that simultaneous In-dustrialization o l many sectors of the economy can be profitable for them all even when no sector can break even industrialking alone. We analy~e this idea in the context of an imperfectly competitive economy with aggregate deman ..."

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 ..."
Abstract - Cited by 284 (7 self) - Add to MetaCart
relevant feelings and experiences. While various measures of well-being are useful for some purposes, it is important to recognize that subjective well-being measures features of individuals' perceptions of their experiences, not their utility as economists typically conceive of it. Those perceptions

Coupled two-way clustering analysis of gene microarray data

by G. Getz, E. Levine, E. Domany - Cell Biology , 2000
"... We present a novel coupled two-way clustering approach to gene microarray data analysis. The main idea is to identify subsets of the genes and samples, such that when one of these is used to cluster the other, stable and significant partitions emerge. The search for such subsets is a computationally ..."

of experimental data. The method was applied to two gene microarray data sets, on colon cancer and leukemia. By identifying relevant subsets of the data and focusing on them we were able to discover partitions and correlations that were masked and hidden when the full dataset was used in the analysis. Some
