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
J. Gonzalez, I. Rojas, H. Pomares, M. Salmeron, J.J. Merelo
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
Yi-Chung Hu, Ruey-Shun Chen, Gwo-Hshiung Tzeng
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
