Statistical pattern recognition: A review

by Anil K. Jain, Robert P. W. Duin, Jianchang Mao - IEEE TRANSACTIONS ON PATTERN ANALYSIS AND MACHINE INTELLIGENCE , 2000
"... The primary goal of pattern recognition is supervised or unsupervised classification. Among the various frameworks in which pattern recognition has been traditionally formulated, the statistical approach has been most intensively studied and used in practice. More recently, neural network techniques ..."

. New and emerging applications, such as data mining, web searching, retrieval of multimedia data, face recognition, and cursive handwriting recognition, require robust and efficient pattern recognition techniques. The objective of this review paper is to summarize and compare some of the well

Model Selection and the Principle of Minimum Description Length

by Mark H. Hansen, Bin Yu - Journal of the American Statistical Association , 1998
"... This paper reviews the principle of Minimum Description Length (MDL) for problems of model selection. By viewing statistical modeling as a means of generating descriptions of observed data, the MDL framework discriminates between competing models based on the complexity of each description. This ..."

A classification of natural rivers.

by David L Rosgen - Catena , 1994
"... Abstract A classification system for natural rivers is presented in which a morphological arrangement of stream characteristics is organized into relatively homogeneous stream types. This paper describes morphologically similar stream reaches that are divided into 7 major stream type categories tha ..."

Eliminating Noisy Information in Web Pages for Data Mining

by Lan Yi - In ACM Conf. on Knowledge Discovery and Data Mining (SIGKDD , 2003
"... A commercial Web page typically contains many information blocks. Apart from the main content blocks, it usually has such blocks as navigation panels, copyright and privacy notices, and advertisements (for business purposes and for easy user access). We call these blocks that are not the main co ..."

content blocks of the page the noisy blocks. We show that the information contained in these noisy blocks can seriously harm Web data mining. Eliminating these noises is thus of great importance. In this paper, we propose a noise elimination technique based on the following observation: In a given

Natural Language Processing for Information Retrieval

by David Lewis, Karen Sparck Jones , 1996
"... The paper summarizes the essential properties of document retrieval and reviews both conventional practice and research findings, the latter suggesting that simple statistical techniques can be effective. It then considers the new opportunities and challenges presented by the ability to search full ..."

Effects of search experience and subject knowledge on the search tactics of novice and experienced searchers

by Lngrid Hsieh-yee - Journal of the American Society for Information Science , 1993
"... This study investigated the effects of subject knowl-edge and search experience on novices ’ and ex-perienced searchers ’ use of search tactics in online searches. Novice and experienced searchers searched a practice question and two test questions in the ERIC database on the DIALOG system and their ..."

Searching in Metric Spaces by Spatial Approximation

by Gonzalo Navarro , 1999
"... We propose a new data structure to search in metric spaces. A metric space is formed by a collection of objects and a distance function defined among them, which satisfies the triangle inequality. The goal is, given a set of objects and a query, retrieve those objects close enough to the query. The ..."

STORAGE AND RETRIEVAL OF DATA

by unknown authors
"... The storage, retrieval, and dissemination of in formation constitutes a major func-tion of any drug information service (DIS). We developed a computerized system for the storage and retrieval of data from drug information requests (DIR) using a MUMPS-based information system. In the past, DIR forms ..."
Abstract - Add to MetaCart
DIR was reviewed and key data elements were selected for input. The DZS files may now be searched online rapidly and efficienrly. The MUMPS-based in formation system has provided open access for all staff pharmacists, 24 hours a day. The benefits have been an increase in both the quantity and quality

Selecting Libraries, Selecting Documents, Selecting Data

by Michael Buckland School, Michael Buckland, Christian Plaunt - In Proceedings of ACM/ISDL , 1997
"... We use "selecting" as a general term for selection processes, including filtering, retrieval, routing, and searching. The search for recorded knowledge in a digital library environment is examined in terms of selection at three levels: 1. Selecting which library (repository) to look in; ..."
