Linear pattern matching algorithms

by Peter Weiner - IN PROCEEDINGS OF THE 14TH ANNUAL IEEE SYMPOSIUM ON SWITCHING AND AUTOMATA THEORY. IEEE , 1972
"... In 1970, Knuth, Pratt, and Morris [1] showed how to do basic pattern matching in linear time. Related problems, such as those discussed in [4], have previously been solved by efficient but sub-optimal algorithms. In this paper, we introduce an interesting data structure called a bi-tree. A linear ti ..."

BASIC PATTERNS IN UFO OBSERVATIONS

by Claude Poher, Jacques Vallee

This paper presents the view that (1) a significant proportion of the thousands of UFO reports analyzed by the authors come from witnesses who have really observed an object in the sky or at ground level; (2) the objects these witnesses have seen have characteristics very different from all identifi ..."

This paper presents the view that (1) a significant proportion of the thousands of UFO reports analyzed by the authors come from witnesses who have really observed an object in the sky or at ground level; (2) the objects these witnesses have seen have characteristics very different from all identifiable objects and phenomena; (3) the phenomenon is of high scientific interest; and (4) a systematic research approach can be defined. These conclusions are based on many years of research into the phenomenon, in the course of which the authors have had at their disposal the official Air Force files of the United States and of France, as well as files of several reliable private organizations. The paper presents the results of computer statistics obtained independently, and it describes some correlations between geomagnetic disturbances and UFO observations.

Mean shift: A robust approach toward feature space analysis

by Dorin Comaniciu, Peter Meer - In PAMI , 2002
"... A general nonparametric technique is proposed for the analysis of a complex multimodal feature space and to delineate arbitrarily shaped clusters in it. The basic computational module of the technique is an old pattern recognition procedure, the mean shift. We prove for discrete data the convergence ..."

The geometry of graphs and some of its algorithmic applications

by Nathan Linial, Eran London, Yuri Rabinovich - 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 graph-theoretic and algorithmic problems. There are several ways to model graphs geometrically and our main concern here is with geometric representations that res ..."

From Data Mining to Knowledge Discovery in Databases.

by Usama Fayyad , Gregory Piatetsky-Shapiro , Padhraic Smyth - AI Magazine, , 1996
"... ■ Data mining and knowledge discovery in databases have been attracting a significant amount of research, industry, and media attention of late. What is all the excitement about?

At an abstract level, the KDD field is concerned with the development of methods and techniques for making sense of data. The basic problem addressed by the KDD process is one of mapping

Basic patterns in national health expenditure

comparisons and linear regressions to describe spending on health and how it is financed. The data cover all sources — out-of-pocket spending, social insurance contributions, financing from government general revenues and voluntary and employment-related private insurance — classified according to their completeness and reliability. Total health spending rises from around 2–3 % of gross domestic product (GDP) at low incomes (<US $ 1000 per capita) to typically 8–9 % at high incomes (>US $ 7000). Surprisingly, there is as much relative variation in the share for poor countries as for rich ones, and even more relative variation in amounts in US$. Poor countries and poor people that most need protection from financial catastrophe are the least protected by any form of prepayment or risk-sharing. At low incomes, out-of-pocket spending is high on average and varies from 20–80 % of the total; at high incomes that share drops sharply and the variation narrows. Absolute out-of-pocket expenditure nonetheless increases with income. Public financing increases faster, and as a share of GDP, and converges at high incomes. Health takes an increasing share of total public expenditure as income rises, from 5–6 % to around 10%. This is arguably the opposite of the relation between total health needs and need for public spending, for any given combination of services. Within public spending, there is no convergence in the type of finance — general revenue versus social insurance. Private insurance is usually insignificant except in some rich countries.

GRASP - A New Search Algorithm for Satisfiability

by Joso L Marques Silva , 1996

This paper introduces GRASP (Generic seaRch Algorithm for the Satisjiability Problem), an integrated algorithmic framework for SAT that un.$es several previously proposed searchpruning techniques and facilitates ident$cation of additional ones. GRASP is premised on the inevitability of confzicts dur ..."

Analyzing confzicts to determine their cawes enables GRASP to backtrack non-chronologically to earlier levels in the search tree, potentially pruning large
