Complexity reduction for "large image" processingIEEE Transactions on Systems, Man, and Cybernetics, Part B (Cybernetics) - Tập 32 Số 5 - Trang 598-611 - 2002
N.R. Pal, J.C. Bezdek
We present a method for sampling feature vectors in large (e.g., 2000 /spl times/ 5000 /spl times/ 16 bit) images that finds subsets of pixel locations which represent c "regions" in the image. Samples are accepted by the chi-square (/spl chi//sup 2/) or divergence hypothesis test. A framework that captures the idea of efficient extension of image processing algorithms from the samples to the rest...... hiện toàn bộ

Web newspaper layout optimization using simulated annealingIEEE Transactions on Systems, Man, and Cybernetics, Part B (Cybernetics) - Tập 32 Số 5 - Trang 686-691 - 2002

The Web newspaper pagination problem consists of optimizing the layout of a set of articles extracted from several Web newspapers and sending it to the user as the result of a previous query. This layout should be organized in columns, as in real newspapers, and should be adapted to the client Web browser configuration in real time. This paper presents an approach to the problem based on simulated...... hiện toàn bộ

A merge-based condensing strategy for multiple prototype classifiersIEEE Transactions on Systems, Man, and Cybernetics, Part B (Cybernetics) - Tập 32 Số 5 - Trang 662-668 - 2002
R.A. Mollineda, F.J. Ferri, E. Vidal
A class-conditional hierarchical clustering framework has been used to generalize and improve previously proposed condensing schemes to obtain multiple prototype classifiers. The proposed method conveniently uses geometric properties and clusters to efficiently obtain reduced sets of prototypes that accurately represent the data while significantly keeping its discriminating power. The benefits of...... hiện toàn bộ

Learning nonlinear multiregression networks based on evolutionary computationIEEE Transactions on Systems, Man, and Cybernetics, Part B (Cybernetics) - Tập 32 Số 5 - Trang 630-644 - 2002
Kwong-Sak Leung, Man-Leung Wong, Wai Lam, Zhenyuan Wang, Kebin Xu
This paper describes a novel knowledge discovery and data mining framework dealing with nonlinear interactions among domain attributes. Our network-based model provides an effective and efficient reasoning procedure to perform prediction and decision making. Unlike many existing paradigms based on linear models, the attribute relationship in our framework is represented by nonlinear nonnegative mu...... hiện toàn bộ

Modified Gath-Geva fuzzy clustering for identification of Takagi-Sugeno fuzzy modelsIEEE Transactions on Systems, Man, and Cybernetics, Part B (Cybernetics) - Tập 32 Số 5 - Trang 612-621 - 2002
J. Abonyi, R. Babuska, F. Szeifert
The construction of interpretable Takagi-Sugeno (TS) fuzzy models by means of clustering is addressed. First, it is shown how the antecedent fuzzy sets and the corresponding consequent parameters of the TS model can be derived from clusters obtained by the Gath-Geva (GG) algorithm. To preserve the partitioning of the antecedent space, linearly transformed input variables can be used in the model. ...... hiện toàn bộ

Defect detection in textured materials using optimized filtersIEEE Transactions on Systems, Man, and Cybernetics, Part B (Cybernetics) - Tập 32 Số 5 - Trang 553-570 - 2002
A. Kumar, G.K.H. Pang
The problem of automated defect detection in textured materials is investigated. A new approach for defect detection using linear FIR filters with optimized energy separation is proposed. The performance of different feature separation criteria with reference to fabric defects has been evaluated. The issues relating to the design of optimal filters for supervised and unsupervised web inspection ar...... hiện toàn bộ

Generating learning sequences for decision makers through data mining and competence set expansionIEEE Transactions on Systems, Man, and Cybernetics, Part B (Cybernetics) - Tập 32 Số 5 - Trang 679-686 - 2002

For each decision problem, there is a competence set, proposed by Yu (1990), consisting of ideas, knowledge, information, and skills required for solving the problem. Thus, it is reasonable that we view a set of useful patterns discovered from a relational database by data mining techniques as a needed competence set for solving one problem. Significantly, when decision makers have not acquired th...... hiện toàn bộ
