Methods based on fuzzy-rough set theory (FRFS) have employed the dependency function to guide the process with much success. This paper presents a novel fuzzy-rough FS technique

It has been shown in [13] and [22] that the standard approach to fuzzy- rough sets uses only the membership of the nearest data object that is of a different class to that of

The 12 different benchmark datasets are drawn from [4]. The class labels are randomly removed from 10%, 30%, 50%, 70% and 90% of the labelled data for each dataset in order to

This paper proposes new techniques for classification using rough sets, and fuzzy-rough sets and applied to this mammographic data, incorporating a fuzzy- rough feature

Table 6.7: The number of selected features and the resulting classification accuracies using fuzzy c -means version of PFS based on decision tree classifier (PFS-DT), PFS based

Conventional supervised FS methods evaluate various feature subsets using an evaluation function or metric to select only those features which are related to, or lead to, the

By extending the discernibility matrix to the fuzzy case, it is possible to employ approaches similar to those in crisp rough set FS to determine fuzzy-rough reducts. A first

Since both approaches involve the analysis of equivalence classes generated from the partitioning of the universe of discourse by sets of features, it is natural, to integrate the

More recently, a fuzzy-rough approach to fuzzy rule induction was presented in [27], where fuzzy reducts are employed to generate rules from data.. This method also employs

The proposed feature selection method is based on the Intuitionistic Fuzzy Entropy, which uses the Intuitionistic Fuzzy C-Means (IFCM) clustering method to compute the

This information loss is one of the main reasons why we introduce fuzzy sets into the models and why fuzzy rough sets are so interesting for feature selection: rough sets let us

In order to evaluate the utility of the new fuzzy- rough measure of feature significance, a series of artificial datasets were generated and used for comparison with 5 other

Motivated by the above observations, we take an incremen- tal approach where a real-valued data set is divided into a sequence of sample subsets that are added in succession, and

In this paper, a new approach to classifier ensemble selection based on fuzzy- rough feature selection and harmony search is proposed.. By transforming the ensemble predictions
