On representation of fuzzy measures for learning Choquet and Sugeno integrals

Knowledge-Based Systems, 2020
This paper examines the marginal contribution representation of fuzzy measures, used to construct fuzzy measure from empirical data through an optimization process.

Feature Selection Using Fuzzy Neighborhood Entropy-Based Uncertainty Measures for Fuzzy Neighborhood Multigranulation Rough Sets

IEEE transactions on fuzzy systems, 2021
For heterogeneous data sets containing numerical and symbolic feature values, feature selection based on fuzzy neighborhood multigranulation rough sets (FNMRS) is a very significant step to preprocess data and improve its classification performance. This

Attribute reduction with fuzzy rough self-information measures

Information Sciences, 2021
The fuzzy rough set is one of the most effective methods for dealing with the fuzziness and uncertainty of data. However, in most cases this model only considers the information provided by the lower approximation of a decision when it is used to ...

A possibility measure is not a fuzzy measure

Fuzzy Sets and Systems, 1982
In the case of metric spaces without isolated points the authors show that every possibility measure with a continuous non vanishing 'density' is not a fuzzy measure. This result is not very surprising, but it corrects a claim mentioned by the way in the literature.

Interactive and Complementary Feature Selection via Fuzzy Multigranularity Uncertainty Measures

IEEE Transactions on Cybernetics, 2021
Feature selection has been studied by many researchers using information theory to select the most informative features. Up to now, however, little attention has been paid to the interactivity and complementarity between features and their relationships.

The Fuzziness Measure in Fuzzy Rough Sets

2008 Fifth International Conference on Fuzzy Systems and Knowledge Discovery, 2008
The paper studies the fuzziness measure in fuzzy rough sets. By making use of the support set of fuzzy sets, a rough membership function for fuzzy sets based on fuzzy relation is introduced. Simultaneously, a fuzziness measure of fuzzy rough sets from total mean fuzzy degree is proposed.

Discernibility Measures for Fuzzy β Covering and Their Application

IEEE Transactions on Cybernetics, 2021
As a combination of fuzzy sets and covering rough sets, fuzzy $\beta $ covering has attracted much attention in recent years. The fuzzy $\beta $ neighborhood serves as the basic granulation unit of fuzzy $\beta $ covering.

On measures of fuzziness

Fuzzy Sets and Systems, 1989
We present a characterization of a fuzzy entropy which is formally analogous to the information theoretical Shannon entropy.
