Several meta-theorems are proposed which state that certain inequalities satisfied by cardinalities of ordinary sets, are preserved under fuzzification.
Biornetrics and Process Control, and Computer Science, (2009)
A family of fuzzification schemes is proposed that can be used to transform cardinality-based similarity measures for ordinary sets into similarity measures for fuzzy sets in a finite universe. These...

B. De Baets, Coupure Links, H. De Meyer, B. De Schuymer
A general framework for studying the transitivity of reciprocal relations is presented. The key feature is the cyclic evaluation of transitivity: triangles (i.e. any three points) are visited in a...

We outline a method for measuring in an efficient way an overall degree of similarity between different leaf-labelled trees. In particular, we consider rooted trees, either unordered or ordered and...
A Generalization of Stochastic and Fuzzy Transitivity for Reciprocal Fuzzy Relations (2009)
H. De Meyer, B. De Baets, S. Jenei
For a reciprocal fuzzy relation Q: x2 + [O, 11 on a finite set of alternatives X, we introduce the concept of U-transitivity which is based upon the ordering of the matrix elements qij, qjk and qki...

Given an involutive negator N and a leftcontinuous t-norm T whose contour line C0 is continuous on]0,1], we build a rotationinvariant t-norm from a rescaled version of T and its left, right and front...
Transitive Comparison of Marginal Probability Distributions (2009)
H. De Meyer, B. De Baets, B. De Schuymer
A generalized dice model for the pairwise comparison of non-necessarily independent random variables is established. It is shown how the transitivity of the probabilistic relation generated by the...
EUSFLAT- LFA 2005 Fitting Piecewise Linear Copulas to Data (2009)
Given a set of n data points (xi, yi, zi) ∈ [0, 1] 3, two methods are established for constructing two piecewise linear copulas, respectively denoted CA(x, y) and CB(x, y), in such a way that...
EUSFLAT- LFA 2005 ON SOME CHARACTERIZATIONS OF COMPLETE FUZZY PREORDERS (2009)
S. Díaz, B. De Baets, S. Montes
We study different characterizations for the transitivity of reflexive fuzzy relations under completeness. We depart from some properties equivalent to the definition of a crisp preorder. We study if...
Department of Applied Mathematics, (2009)
Contour lines totally fix the structure of leftcontinuous t-norms. For each t-norm, these contour lines are determined by the corresponding residual implicator. Most properties involving residual...
Disjunctive and Conjunctive Normal Forms in Fuzzy Logic (2008)
K. Maes, B. De Baets, J. Fodor
When performing set-theoretical operations, such as intersection and union, on fuzzy sets, one can opt not to consider exact formula, but to leave the results less specific (in particular,...
Modelling groundwater-dependent vegetation patterns using ensemble learning (2008)
J. Peters, B. De Baets, R. Samson
Vegetation patterns arise from the interplay between intraspecific and interspecific biotic interactions and from different abiotic constraints and interacting driving forces and distributions. In...
Modelling groundwater-dependent vegetation patterns using ensemble learning (2007)
J. Peters, B. De Baets, R. Samson
Vegetation patterns arise from the interplay between intraspecific and interspecific biotic interactions and from different abiotic constraints and interacting driving forces and distributions. In...

With the explosive growth of the amount of digital music available on the Internet, Musical Information Retrieval (MIR) has become a topic that has attracted the attention of researchers
Designing Neural Networks Using Gene Expression Programming (2004)
Cândida Ferreira, In A. Abraham, B. De Baets, B. Nickolay
Abstract. An artificial neural network with all its elements is a rather complex structure, not easily constructed and/or trained to perform a particular task. Consequently, several researchers used...

In this paper recent improvements of an existing acoustic frontend for the transcription of vocal (hummed, sung) musical queries is presented. Thanks to the addition of a new second pitch extractor...
Distance-based versus Tree-based Key Recognition in Musical Audio (2003)
H. De Meyer, B. De Baets, M. Leman, M. Lesaffre, ...
A new method for the recognition of the tonal center or key in a musical audio signal is presented. Time-varying key feature vectors of 264 synthesized sounds are extracted from an auditory-based...
