On the generalization of fuzzy rough sets

TL;DR: In this paper, some definitions of upper and lower approximation operators of fuzzy sets by means of arbitrary fuzzy relations are proposed and a special lower approximation operator is applied to a fuzzy reasoning system, which coincides with the Mamdani algorithm.
Journal ArticleDOI

Architecture selection for networks trained with extreme learning machine using localized generalization error model

TL;DR: Experimental results on a number of benchmark data sets show that an approximately optimal architecture in terms of number of neurons of a SLFN can be found using the extended LGEM, and the experimental results on eleven UCI data sets shows that the proposed method is effective and efficient.
Journal ArticleDOI

On the handling of fuzziness for continuous-valued attributes in decision tree generation

TL;DR: Fuzziness existing in the process of generating decision trees by discretizing continuous-valued attributes is considered and a better way to express this fuzziness via fuzzy numbers is presented using possibility theory.
Journal ArticleDOI

Fuzzy linear regression analysis

TL;DR: The Minmax estimation of the regression model parameters and the LS estimation ofThe approximation model parameters are discussed and procedures of estimating these parameters are given.
Journal Article

Research on the Image Feature Extraction

TL;DR: This review introduces the basic ideas of image feature extraction, their major characteristics and some current research trends.
