A MarketOriented Programming Environment and its Application to Distributed Multicommodity Flow Problems
 Journal of Artificial Intelligence Research
, 1993
"... Market price systems constitute a wellunderstood class of mechanisms that under certain conditions provide effective decentralization of decision making with minimal communication overhead. In a marketoriented programming approach to distributed problem solving, we derive the activities and resour ..."

Additive Logistic Regression: a Statistical View of Boosting
 Annals of Statistics
, 1998
"... Boosting (Freund & Schapire 1996, Schapire & Singer 1998) is one of the most important recent developments in classification methodology. The performance of many classification algorithms can often be dramatically improved by sequentially applying them to reweighted versions of the input dat ..."

data, and taking a weighted majority vote of the sequence of classifiers thereby produced. We show that this seemingly mysterious phenomenon can be understood in terms of well known statistical principles, namely additive modeling and maximum likelihood. For the twoclass problem, boosting can
Efficient Mining of Emerging Patterns: Discovering Trends and Differences
, 1999
"... We introduce a new kind of patterns, called emerging patterns (EPs), for knowledge discovery from databases. EPs are defined as itemsets whose supports increase significantly from one dataset to another. EPs can capture emerging trends in timestamped databases, or useful contrasts between data clas ..."

classes. EPs have been proven useful: we have used them to build very powerful classifiers, which are more accurate than C4.5 and CBA, for many datasets. We believe that EPs with low to medium support, such as 1% 20%, can give useful new insights and guidance to experts, in even "well understood
An Evolutionary Algorithm that Constructs Recurrent Neural Networks
 IEEE TRANSACTIONS ON NEURAL NETWORKS
"... Standard methods for inducing both the structure and weight values of recurrent neural networks fit an assumed class of architectures to every task. This simplification is necessary because the interactions between network structure and function are not well understood. Evolutionary computation, whi ..."

OneClass SVMs for Document Classification
 Journal of Machine Learning Research
, 2001
"... We implemented versions of the SVM appropriate for oneclass classification in the context of information retrieval. The experiments were conducted on the standard Reuters data set. For the SVM implementation we used both a version of Schölkopf et al. and a somewhat different version of oneclass SV ..."

to all the methods except the neural network one, where it was, although occasionally worse, essentially comparable. However, the SVM methods turned out to be quite sensitive to the choice of representation and kernel in ways which are not well understood; therefore, for the time being leaving the neural
Principles of microRNAtarget recognition
 PLoS Biol
, 2005
"... MicroRNAs (miRNAs) are short noncoding RNAs that regulate gene expression in plants and animals. Although their biological importance has become clear, how they recognize and regulate target genes remains less well understood. Here, we systematically evaluate the minimal requirements for functional ..."

"... The 727dimensional root space associated with the level2 root Λ1 of the hyperbolic Kac–Moody algebra E10 is determined using a recently developed string theoretic approach to hyperbolic algebras. The explicit form of the basis reveals a complicated structure with transversal as well as longitudina ..."

The Kac–Moody algebras associated with indefinite Cartan matrices, however, have so far resisted attempts
Accurate information extraction from research papers using conditional random fields
 HLTNAACL04
, 2004
"... With the increasing use of research paper search engines, such as CiteSeer, for both literature search and hiring decisions, the accuracy of such systems is of paramount importance. This paper employs Conditional Random Fields (CRFs) for the task of extracting various common fields from the headers ..."

This paper makes an empirical exploration of several factors, including variations on Gaussian, exponential and hyperbolicL1 priors
RANK AND STATUS IN SEMIGROUP THEORY12
"... For each generating set A of a finite semigroup S the integer ∆(A) is defined as the least n for which every element of S is expressible as a product of at most n elements of A. The status of S is defined as the least value of A∆(A) among generating sets of A. Some general bounds are obtained, and ..."

Design and Evaluation of a Continuous Consistency Model for Replicated Services

Traditionally, however, designers of replicated systems have been forced to choose from either strong consistency guarantees or none at all. This paper explores the semantic space between traditional strong and opt ..."
