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

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

Hierarchical semi-numeric method for pairwise fuzzy group decision makingIEEE Transactions on Systems, Man, and Cybernetics, Part B (Cybernetics) - Tập 32 Số 5 - Trang 691-700 - 2002
M. Marimin, M. Umano, I. Hatono, H. Tamura
Gradual improvements to a single-level semi-numeric method, i.e., linguistic labels preference representation by fuzzy sets computation for pairwise fuzzy group decision making are summarized. The method is extended to solve multiple criteria hierarchical structure pairwise fuzzy group decision-making problems. The problems are hierarchically structured into focus, criteria, and alternatives. Deci...... hiện toàn bộ

A reduction approach for fuzzy rule bases of fuzzy controllersIEEE Transactions on Systems, Man, and Cybernetics, Part B (Cybernetics) - Tập 32 Số 5 - Trang 668-675 - 2002
C.W. Tao
In this paper, a new approach to reducing the number of rules in a given fuzzy rule base of a fuzzy controller is presented. The fuzzy mechanism of the fuzzy controller under consideration consists of the product-sum inference, singleton output consequents and centroid defuzzification. The output consequents in the cells of the rule table are collected and represented as an output consequent matri...... hiện toàn bộ

An evolutionary tabu search for cell image segmentationIEEE Transactions on Systems, Man, and Cybernetics, Part B (Cybernetics) - Tập 32 Số 5 - Trang 675-678 - 2002
Tianzi Jiang, Faguo Yang
Many engineering problems can be formulated as optimization problems. It has become more and more important to develop an efficient global optimization technique for solving these problems. In this paper, we propose an evolutionary tabu search (ETS) for cell image segmentation. The advantages of genetic algorithms (GA) and TS algorithms are incorporated into the proposed method. More precisely, we...... hiện toàn bộ

Adaptive hybrid intelligent control for uncertain nonlinear dynamical systemsIEEE Transactions on Systems, Man, and Cybernetics, Part B (Cybernetics) - Tập 32 Số 5 - Trang 583-597 - 2002
Chi-Hsu Wang, Tsung-Chih Lin, Tsu-Tian Lee, Han-Leih Liu
A new hybrid direct/indirect adaptive fuzzy neural network (FNN) controller with a state observer and supervisory controller for a class of uncertain nonlinear dynamic systems is developed in this paper. The hybrid adaptive FNN controller, the free parameters of which can be tuned on-line by an observer-based output feedback control law and adaptive law, is a combination of direct and indirect ada...... hiện toàn bộ

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

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
