Constraint-based mining and inductive databases : European Workshop on Inductive Databases and Constraint Based Mining, Hinterzarten, Germany, March 11-13, 2004 : revised selected papers by Jean-François Boulicaut( )

21 editions published between 2005 and 2006 in English and Undetermined and held by 598 WorldCat member libraries worldwide

The interconnected ideas of inductive databases and constraint-based mining are appealing and have the potential to radically change the theory and practice of data mining and knowledge discovery. This book reports on the results of the European IST project "cInQ" (consortium on knowledge discovery by Inductive Queries) and its final workshop entitled Constraint-Based Mining and Inductive Databases organized in Hinterzarten, Germany in March 2004. The 18 articles in this state-of-the-art survey present the latest results in inductive querying and constraint-based data mining and also identify future directions of this newly emerging field lying at the intersection of data mining and database research. The papers address topical sections on foundations of inductive database frameworks, optimizing inductive queries on local patterns, optimizing inductive queries on global patterns, and applications of inductive querying techniques
Algorithms and applications : essay dedicated to Esko Ukkonen on the occasion of his 60th birthday by Tapio Elomaa( )

9 editions published in 2010 in English and held by 440 WorldCat member libraries worldwide

For many years Esko Ukkonen has played a major role in the advancement of computer science in Finland. He was the key person in the development of the school of algorithmic research and has contributed considerably to post-graduate education in his country. Esko Ukkonen has over the years worked within many areas of computer science, including numerical methods, complexity theory, theoretical aspects of compiler construction, and logic programming. However, the main focus of his research has been on algorithms and their applications. This Festschrift volume, published to honor Esko Ukkonen on his 60th birthday, includes 18 refereed contributions by his former PhD students and colleagues, with whom he has cooperated closely during the course of his career. The Festschrift was presented to Esko during a festive symposium organized at the University of Helsinki to celebrate his birthday. The essays primarily present research on computational pattern matching and string algorithms, two areas that have benefited significantly from the work of Esko Ukonen

Right invariant metrics and measures of presortedness by Vladmir Estivill-Castro( Book )

2 editions published in 1989 in English and held by 7 WorldCat member libraries worldwide

Abstract: "Right invariant metrics (ri-metrics) have several applications in the theory of rank correlation methods. For example, ranking models based on ri-metrics generalize Mallow's ranking models. We explore the relationship between right invariant metrics and measures of presortedness (mops). The latter have been used to evaluate the behavior of sorting algorithms on nearly-sorted inputs. We give necessary and sufficient conditions for a measure of presortedness to be extended to a ri-metric; we characterize those ri-metrics that can be used as mops; and we show that those mops that are extendible to ri-metrics can be constructed from sets of sorting operations. Our results provide a paradigm to construct mops and ri-metrics."
Discovering all most specific sentences by randomized algorithms by Dimitrios Gunopulos( Book )

2 editions published in 1996 in English and held by 6 WorldCat member libraries worldwide

Abstract: "Data mining can in many instances be viewed as the task of computing a representation of a theory of a model or a database. In this paper we present a randomized algorithm that can be used to compute the representation of a theory in terms of the most specific sentences of that theory. In addition to randomization, the algorithm uses a generalization of the concept of hypergraph transversal. We apply the general algorithm in two ways, for the problem of discovering maximal frequent sets in 0/1 data, and for computing minimal keys in relations. We present some empirical results on the performance of these methods on real data. We also show some complexity theoretic evidence of the hardness of these problems."
Recognizing renamable generalized propositional Horn formulas is NP-complete by Thomas Eiter( Book )

4 editions published in 1992 in English and held by 6 WorldCat member libraries worldwide

Abstract: "Yamasaki and Doshita have defined an extension of the class of propositional Horn formulas; later, Gallo and Scutellà generalized this class to a hierarchy [formula], where [gamma]₀ is the set of Horn formulas and [gamma]₁ is the class of Yamasaki and Doshita. For any fixed k, the propositional formulas in [gamma][subscript k] can be recognized in polynomial time, and the satisfiability problem for [gamma][subscript k] formulas can be solved in polynomial time. A possible way of extending these tractable subclasses of the satisfiability problem is to consider renamings: a renaming of a formula is obtained by replacing for some variables all their positive occurrences by negative occurrences and vice versa
Ordered and unordered tree inclusion by Pekka Kilpeläinen( Book )

4 editions published in 1991 in English and held by 6 WorldCat member libraries worldwide

Abstract: "We consider the following problem: Given labeled trees P and T, can P be obtained from T by deleting nodes? Deleting a node v entails removing all edges incident to v, and if v has a parent u, replacing the edge from u to v by edges from u to the children of v. The problem is motivated by the study of query languages for structured text data bases. Simple solutions to this problem require exponential time. For ordered trees we present an algorithm that requires [formula] time and space. We also consider the corresponding problem for unordered trees and give a proof of its NP-completeness."

Design by example : an application of Armstrong relations by Heikki Mannila( Book )

3 editions published in 1985 in English and held by 5 WorldCat member libraries worldwide

Example relations, and especially Armstrong relations, can be used as user-friendly representations of dependency sets. In this paper we analyze the use of Armstrong relations in database design with functional dependencies, and show how they and the usual representation of dependencies can be used together. Special attention is given to the size of Armstrong relations. We derive new bounds for the size of minimal Armstrong relations for normalized schemes. New algorithms are also given for generating Armstrong relations and for inferring the functional dependencies holding in a relation
