LexRank: Graphbased lexical centrality as salience in text summarization
 Journal of Artificial Intelligence Research
, 2004
"... We introduce a stochastic graphbased method for computing relative importance of textual units for Natural Language Processing. We test the technique on the problem of Text Summarization (TS). Extractive TS relies on the concept of sentence salience to identify the most important sentences in a doc ..."

a detailed analysis of our approach and apply it to a larger data set including data from earlier DUC evaluations. We discuss several methods to compute centrality using the similarity graph. The results show that degreebased methods (including LexRank) outperform both centroidbased methods
Frequency estimation of internet packet streams with limited space
 IN PROCEEDINGS OF THE 10TH ANNUAL EUROPEAN SYMPOSIUM ON ALGORITHMS
, 2002
"... We consider a router on the Internet analyzing the statistical properties of a TCP/IP packet stream. A fundamental difficulty with measuring traffic behavior on the Internet is that there is simply too much data to be recorded for later analysis, on the order of gigabytes a second. As a result, net ..."

, network routers can collect only relatively few statistics about the data. The central problem addressed here is to use the limited memory of routers to determine essential features of the network traffic stream. A particularly difficult and representative subproblem is to determine the top k categories
A critical role for the right frontoinsular cortex in switching between centralexecutive and defaultmode networks.
 Proc Natl Acad Sci USA
, 2008
"... Cognitively demanding tasks that evoke activation in the brain's centralexecutive network (CEN) have been consistently shown to evoke decreased activation (deactivation) in the defaultmode network (DMN). The neural mechanisms underlying this switch between activation and deactivation of larg ..."

The Convex Geometry of Linear Inverse Problems
, 2010
"... In applications throughout science and engineering one is often faced with the challenge of solving an illposed inverse problem, where the number of available measurements is smaller than the dimension of the model to be estimated. However in many practical situations of interest, models are constr ..."

Benchmarking attribute selection techniques for discrete class data mining
 IEEE Trans. Knowl. Data Eng
"... Data engineering is generally considered to be a central issue in the development of data mining applications. The success of many learning schemes, in their attempts to construct models of data, hinges on the reliable identification of a small set of highly predictive attributes. The inclusion of i ..."

On the Betti numbers of real varieties
 Proc. Amer. Math. Soc
, 1964
"... The object of this note will be to give an upper bound for the sum of the Betti numbers of a real affine algebraic variety. (Added in proof. Similar results have been obtained by R. Thom [lO].) Let F be a variety in the real Cartesian space Rm, defined by polynomial equations /i(xi, ■ ■ ■ , xm) ..."

Coil sensitivity encoding for fast MRI. In:
 Proceedings of the ISMRM 6th Annual Meeting,
, 1998
"... New theoretical and practical concepts are presented for considerably enhancing the performance of magnetic resonance imaging (MRI) by means of arrays of multiple receiver coils. Sensitivity encoding (SENSE) is based on the fact that receiver sensitivity generally has an encoding effect complementa ..."

Gradience in grammar: Experimental and computational aspects of degrees of grammaticality
, 2000
"... This thesis deals with gradience in grammar, i.e., with the fact that some linguistic structures are not fully acceptable or unacceptable, but receive gradient linguistic judgments. The importance of gradient data for linguistic theory has been recognized at least since Chomsky’s Logical Structure o ..."

They cover all major modules of syntactic theory, and draw on data from three languages (English, German, and Greek). In the theoretical part
The central role of noise in evaluating interventions that use test scores to rank schools
 American Economic Review
, 2005
"... anonymous referees. We are also grateful to Cristián Cox and many officials of Chile’s Ministry of Many programs reward or penalize schools based upon students ’ average performance. Kane and Staiger (2001) warn that imprecision in the measurement of schoollevel test scores could impede these effor ..."

We then show how a regression discontinuity (RD) design that utilizes the discrete nature of the selection rule can be used to control for reversion
Openness, imperfect exchange rate passthrough and monetary policy
 FORTHCOMING IN JOURNAL OF MONETARY ECONOMICS

This paper analyses the implications of imperfect exchange rate passthrough for optimal monetary policy in a linearised openeconomy dynamic general equilibrium model calibrated to euro area data. Imperfect exchange rate pass through is modelled by assuming sticky import price behaviour. The degree ..."

The degree of domestic and import price stickiness is estimated by reproducing the empirical identified impulse response of a monetary policy and exchange rate shock conditional on the response of output, net trade and the exchange rate. It is shown that a central bank that wants to minimise the resource
