Propensity Score Matching Methods For Non-Experimental Causal Studies

by Rajeev H. Dehejia, Sadek Wahba , 2002
"... This paper considers causal inference and sample selection bias in non-experimental settings in which: (i) few units in the non-experimental comparison group are comparable to the treatment units; and (ii) selecting a subset of comparison units similar to the treatment units is difficult because uni ..."

Efficient belief propagation for early vision

by Pedro F. Felzenszwalb, Daniel P. Huttenlocher - In CVPR , 2004
"... Markov random field models provide a robust and unified framework for early vision problems such as stereo, optical flow and image restoration. Inference algorithms based on graph cuts and belief propagation yield accurate results, but despite recent advances are often still too slow for practical u ..."

CCured: Type-Safe Retrofitting of Legacy Code

by George C. Necula, Scott McPeak, Westley Weimer - PRINCIPLES OF PROGRAMMING LANGUAGES , 2002
"... In this paper we propose a scheme that combines type inference and run-time checking to make existing C programs type safe. We describe the CCured type system, which extends that of C by separating pointer types according to their usage. This type system allows both pointers whose usage can be verif ..."

The pascal recognising textual entailment challenge

by Ido Dagan, Oren Glickman - In Proceedings of the PASCAL Challenges Workshop on Recognising Textual Entailment , 2005
"... This paper describes the PASCAL Network of Excellence Recognising Textual Entailment (RTE) Challenge benchmark 1. The RTE task is defined as recognizing, given two text fragments, whether the meaning of one text can be inferred (entailed) from the other. This applicationindependent task is suggested ..."

"... SEQUELS ARE RARELY AS good as the originals, so I approach this review of the market efflciency literature with trepidation. The task is thornier than it was 20 years ago, when work on efficiency was rather new. The literature is now so large that a full review is impossible, and is not attempted h ..."

I can focus instead on the more interesting task of laying out the evidence on the adjustment of prices to various kinds of information. Each reader is then free to judge

Mutual Fund Flows and Performance in Rational Markets

by Jonathan B. Berk, Richard C. Green , 2002
"... We develop a simple rational model of active portfolio management that provides a natural benchmark against which to evaluate observed relationship between returns and fund flows. Many effects widely regarded as anomalous are consistent with this simple explanation. In the model, investments with ac ..."

with active managers do not outperform passive benchmarks because of the competitive market for capital provision, combined with decreasing returns to scale in active portfolio management. Consequently, past performance cannot be used to predict future returns, or to infer the average skill level of active

Classification in Networked Data: A toolkit and a univariate case study

by Sofus A. Macskassy, Foster Provost , 2006
"... This paper is about classifying entities that are interlinked with entities for which the class is known. After surveying prior work, we present NetKit, a modular toolkit for classification in networked data, and a case-study of its application to networked data used in prior machine learning resear ..."

research. NetKit is based on a node-centric framework in which classifiers comprise a local classifier, a relational classifier, and a collective inference procedure. Various existing node-centric relational learning algorithms can be instantiated with appropriate choices for these components, and new

STRING: a database of predicted functional associations between proteins

by Christian Von Mering, Martijn Huynen, Daniel Jaeggi, Steffen Schmidt, Peer Bork, Berend Snel - Nucleic Acids Res , 2003
"... Functional links between proteins can often be inferred from genomic associations between the genes that encode them: groups of genes that are required for the same function tend to show similar species coverage, are often located in close proximity on the genome (in prokaryotes), and tend to be inv ..."

Thus, STRING contains a unique scoring-framework based on benchmarks of the different types of associations against a common reference set, integrated in a single confidence score per prediction.

Infernal 1.0: Inference of RNA Alignments

by Eric P. Nawrocki, Diana L. Kolbe, Sean R. Eddy - Bioinformatics , 2009
"... Summary: INFERNAL builds consensus RNA secondary structure profiles called covariance models (CMs), and uses them to search nucleic acid sequence databases for homologous RNAs, or to create new sequence- and structure-based multiple sequence alignments. Availability: Source code, documentation, and ..."

Predicting protein function by genomic context: quantitative evaluation and qualitative inferences

by Martijn Huynen, Berend Snel, Warren Lathe Iii, Peer Bork - Genome Res , 2000
"... Various new methods have been proposed to predict functional interactions between proteins based on the genomic context of their genes. The types of genomic context that they use are Type I: the fusion of genes; Type II: the conservation of gene-order or co-occurrence of genes in potential operons; ..."

By combining gene order conservation with gene fusion (6%), the co-occurrence of genes in operons in absence of gene
