Privacy-Preserving Data Mining

by Rakesh Agrawal , Ramakrishnan Srikant , 2000
"... A fruitful direction for future data mining research will be the development of techniques that incorporate privacy concerns. Specifically, we address the following question. Since the primary task in data mining is the development of models about aggregated data, can we develop accurate models with ..."

without access to precise information in individual data records? We consider the concrete case of building a decision-tree classifier from tredning data in which the values of individual records have been perturbed. The resulting data records look very different from the original records

Heuristic Evaluation of User Interfaces

by Jukob Nielsen, Rolf Molich - IN: PROCEEDINGS OF THE CHI´90 CONFERENCE, SEATTLE , 1990
"... Heuristic evaluation is an informal method of usability analysis where a number of evaluators are presented with an interface design and asked to comment on it. Four ex-periments showed that individual evaluators were mostly quite bad at doing such heuristic evaluations and that they only found betw ..."

Modeling the Shape of the Scene: A Holistic Representation of the Spatial Envelope

by Aude Oliva, Antonio Torralba - International Journal of Computer Vision , 2001
"... In this paper, we propose a computational model of the recognition of real world scenes that bypasses the segmentation and the processing of individual objects or regions. The procedure is based on a very low dimensional representation of the scene, that we term the Spatial Envelope. We propose a se ..."

Grouplens: Applying collaborative filtering to usenet news

by Joseph A. Konstan, Bradley N. Miller, David Maltz, Jonathan L. Herlocker, Lee R. Gordon, John Riedl - COMMUNICATIONS OF THE ACM , 1997
"... ... a collaborative filtering system for Usenet news—a high-volume, high-turnover discussion list service on the Internet. Usenet newsgroups—the individual discussion lists—may carry hundreds of messages each day. While in theory the newsgroup organization allows readers to select the content that m ..."

that most interests them, in practice most newsgroups carry a wide enough spread of messages to make most individuals consider Usenet news to be a high noise information resource. Furthermore, each user values a different set of messages. Both taste and prior knowledge are major factors in evaluating news

k-anonymity: a model for protecting privacy.

by Latanya Sweeney - International Journal on Uncertainty, Fuzziness and Knowledge-based Systems, , 2002
"... Consider a data holder, such as a hospital or a bank, that has a privately held collection of person-specific, field structured data. Suppose the data holder wants to share a version of the data with researchers. How can a data holder release a version of its private data with scientific guarantees ..."

This paper also examines re-identification attacks that can be realized on releases that adhere to kanonymity unless accompanying

Electronic Markets and Electronic Hierarchies

by Robert I. Benjamin, Thomas W. Malone, Joanne Yates - Communications of the ACM , 1987
"... This paper analyzes the fundamental changes in market structures that may result from the increasing use of information technology. First, an analytic framework is presented and its usefulness is demonstrated in explaining several major historical changes in American business structures. Then, the f ..."

Context-Aware Computing Applications

by Bill Schilit, Norman Adams, Roy Want , 1995
"... This paper describes systems that examine and react to an individual's changing context. Such systems can promote and mediate people's mleractlOns with devices, computers, and other people, and they can help navigate unfamiliar places.

Fast and robust fixed-point algorithms for independent component analysis

by Aapo Hyvärinen - IEEE TRANS. NEURAL NETW , 1999
"... Independent component analysis (ICA) is a statistical method for transforming an observed multidimensional random vector into components that are statistically as independent from each other as possible. In this paper, we use a combination of two different approaches for linear ICA: Comon’s informat ..."

information-theoretic approach and the projection pursuit approach. Using maximum entropy approximations of differential entropy, we introduce a family of new contrast (objective) functions for ICA. These contrast functions enable both the estimation of the whole decomposition by minimizing mutual information

A comparison of bayesian methods for haplotype reconstruction from population genotype data.

by Matthew Stephens , Peter Donnelly , Dr Matthew Stephens - Am J Hum Genet , 2003
"... In this report, we compare and contrast three previously published Bayesian methods for inferring haplotypes from genotype data in a population sample. We review the methods, emphasizing the differences between them in terms of both the models ("priors") they use and the computational str ..."

PHASE, version 2.0, available online (http://www.stat.washington.edu/stephens/ software.html). Current high-throughput genotyping technologies, when applied to DNA from a diploid individual, are able to determine which two alleles are present at each locus but not the haplotype information (that is

Costly search and mutual fund flows

by Erik R. Sirri, Peter Tufano - Journal of Finance , 1998
"... This paper studies the flows of funds into and out of equity mutual funds. Consumers base their fund purchase decisions on prior performance information, but do so asymmetrically, investing disproportionately more in funds that performed very well the prior period. Search costs seem to be an importa ..."
