Traversing Itemset Lattices with Statistical Metric Pruning
 In Proc. of the 19th ACM SIGACTSIGMODSIGART Symposium on Principles of Database Systems
, 2000
"... We study how to efficiently compute significant association rules according to common statistical measures such as a chisquared value or correlation coefficient. For this purpose, one might consider to use of the Apriori algorithm, but the algorithm needs major conversion, because none of these sta ..."

of these statistical metrics are antimonotone, and the use of higher support for reducing the search space cannot guarantee solutions in its the search space. We here present a method of estimating a tight upper bound on the statistical metric associated with any superset of an itemset, as well as the novel use
Learning Bayesian networks: The combination of knowledge and statistical data
 Machine Learning
, 1995
"... We describe scoring metrics for learning Bayesian networks from a combination of user knowledge and statistical data. We identify two important properties of metrics, which we call event equivalence and parameter modularity. These properties have been mostly ignored, but when combined, greatly simpl ..."

A hierarchical phrasebased model for statistical machine translation
 IN ACL
, 2005
"... We present a statistical phrasebased translation model that uses hierarchical phrases— phrases that contain subphrases. The model is formally a synchronous contextfree grammar but is learned from a bitext without any syntactic information. Thus it can be seen as a shift to the formal machinery of ..."

Hierarchical phrasebased translation
 Computational Linguistics

The model is formally a synchronous contextfree grammar but is learned from a parallel text without any syntactic annotations. Thus it can be seen as combining fundamental ideas from b ..."

An intrusiondetection model
 IEEE TRANSACTIONS ON SOFTWARE ENGINEERING
, 1987
"... A model of a realtime intrusiondetection expert system capable of detecting breakins, penetrations, and other forms of computer abuse is described. The model is based on the hypothesis that security violations can be detected by monitoring a system's audit records for abnormal patterns of sy ..."

of system usage. The model includes profiles for representing the behavior of subjects with respect to objects in terms of metrics and statistical models, and rules for acquiring knowledge about this behavior from audit records and for detecting anomalous behavior. The model is independent of any particular
Cognitive Radio: BrainEmpowered Wireless Communications
, 2005
"... Cognitive radio is viewed as a novel approach for improving the utilization of a precious natural resource: the radio electromagnetic spectrum. The cognitive radio, built on a softwaredefined radio, is defined as an intelligent wireless communication system that is aware of its environment and use ..."

and uses the methodology of understandingbybuilding to learn from the environment and adapt to statistical variations in the input stimuli, with two primary objectives in mind: • highly reliable communication whenever and wherever needed; • efficient utilization of the radio spectrum. Following
Axiomatic quantum field theory in curved spacetime
, 2008
"... The usual formulations of quantum field theory in Minkowski spacetime make crucial use of features—such as Poincare invariance and the existence of a preferred vacuum state—that are very special to Minkowski spacetime. In order to generalize the formulation of quantum field theory to arbitrary globa ..."

The geometry of graphs and some of its algorithmic applications
 COMBINATORICA
, 1995
"... In this paper we explore some implications of viewing graphs as geometric objects. This approach offers a new perspective on a number of graphtheoretic and algorithmic problems. There are several ways to model graphs geometrically and our main concern here is with geometric representations that res ..."

that respect the metric of the (possibly weighted) graph. Given a graph G we map its vertices to a normed space in an attempt to (i) Keep down the dimension of the host space and (ii) Guarantee a small distortion, i.e., make sure that distances between vertices in G closely match the distances between
INDUCTIVE SYSTEM HEALTH MONITORING WITH STATISTICAL METRICS __________________________________
"... Modelbased reasoning is a powerful method for performing system monitoring and diagnosis. Building models for modelbased reasoning is often a difficult and time consuming process. The Inductive Monitoring System (IMS) software was developed to provide a technique to automatically produce health mo ..."

During monitoring, IMS provides a statistically weighted measure of the deviation of current system behavior from the established normal baseline. If the deviation increases beyond
The DaCapo Benchmarks: Java Benchmarking Development and Analysis
"... Since benchmarks drive computer science research and industry product development, which ones we use and how we evaluate them are key questions for the community. Despite complex runtime tradeoffs due to dynamic compilation and garbage collection required for Java programs, many evaluations still us ..."

No benchmark suite is definitive, but these metrics show that DaCapo improves over SPEC Java in a variety of ways
