Unique pattern matching in strings

by Stijn Vansummeren , 2003
"... Abstract. Regular expression patterns are a key feature of document processing languages like Perl and XDuce. It is in this context that the first and longest match policies have been proposed to disambiguate the pattern matching process. We formally define a matching semantics with these policies a ..."

gSpan: Graph-Based Substructure Pattern Mining

by Xifeng Yan, Jiawei Han , 2002
"... We investigate new approaches for frequent graph-based pattern mining in graph datasets and propose a novel algorithm called gSpan (graph-based Substructure pattern mining) , which discovers frequent substructures without candidate generation. gSpan builds a new lexicographic order among graphs, and ..."

A tutorial on support vector machines for pattern recognition

by Christopher J. C. Burges - Data Mining and Knowledge Discovery , 1998
"... The tutorial starts with an overview of the concepts of VC dimension and structural risk minimization. We then describe linear Support Vector Machines (SVMs) for separable and non-separable data, working through a non-trivial example in detail. We describe a mechanical analogy, and discuss when SV ..."
Abstract - Cited by 3393 (12 self) - Add to MetaCart
SVM solutions are unique and when they are global. We describe how support vector training can be practically implemented, and discuss in detail the kernel mapping technique which is used to construct SVM solutions which are nonlinear in the data. We show how Support Vector machines can have very

Data Preparation for Mining World Wide Web Browsing Patterns

by Robert Cooley, Bamshad Mobasher, Jaideep Srivastava - KNOWLEDGE AND INFORMATION SYSTEMS , 1999
"... The World Wide Web (WWW) continues to grow at an astounding rate in both the sheer volume of tra#c and the size and complexity of Web sites. The complexity of tasks such as Web site design, Web server design, and of simply navigating through a Web site have increased along with this growth. An i ..."

server logs. This paper presents several data preparation techniques in order to identify unique users and user sessions. Also, a method to divide user sessions into semantically meaningful transactions is defined and successfully tested against two other methods. Transactions identified

Type Inference for Unique Pattern Matching

by STIJN VANSUMMEREN
"... Regular expression patterns provide a natural, declarative way to express constraints on semistructured data and to extract relevant information from it. Indeed, it is a core feature of the programming language Perl, surfaces in various UNIX tools such as sed and awk, and has recently been proposed ..."

Implementation and performance of Munin

by John B. Carter, John K. Bennett, Willy Zwaenepoel - IN PROCEEDINGS OF THE 13TH ACM SYMPOSIUM ON OPERATING SYSTEMS PRINCIPLES , 1991
"... Munin is a distributed shared memory (DSM) system that allows shared memory parallel programs to be executed efficiently on distributed memory multiprocessors. Munin is unique among existing DSM systems in its use of multiple consistency protocols and in its use of release consistency. In Munin, sha ..."

High confidence visual recognition of persons by a test of statistical independence

by John G. Daugman - IEEE TRANS. ON PATTERN ANALYSIS AND MACHINE INTELLIGENCE , 1993
"... A method for rapid visual recognition of personal identity is described, based on the failure of a statistical test of independence. The most unique phenotypic feature visible in a person’s face is the detailed texture of each eye’s iris: An estimate of its statistical complexity in a sample of the ..."

We also sh ..."

Mosaic analysis with a repressible cell marker for studies of gene function in neuronal morphogenesis.

by Tzumin Lee , Liqun Luo - Neuron , 1999
"... We have modified an FLP/FRT-based genetic mosaic system to label either neurons derived from a common progenitor or isolated single neurons, in the Drosophila CNS. These uniquely labeled neurons can also be made homozygous for a mutation of interest within an otherwise phenotypically wild-type brai ..."

Unique patterns of regulation of nitric oxide production in fibroblasts

by Natasha Lavnikova, Debra L. Laskin - J Leukoc Biol , 1995
"... Abstract: The pathways regulating rat and mouse embryonic and lung fibroblast nitric oxide production were analyzed in an attempt to evaluate the potential role of these cells in nonspecific host defense and inflammation. Interleukin-i (IL-in) was found to be the strongest single activator in all t ..."
Abstract - Cited by 7 (1 self) - Add to MetaCart
types of fibroblasts examined. In addition, lipopolysaccharide (LPS) was synergistic with IL-1 or tumor necrosis factor-ct (TNF-cx) in induction of nitric oxide synthesis. These patterns ofresponsiveness are not observed in macro-phages and may be significant in initiation of early host defense
