Abstract :
Rough sets approach of attributes reduction can be used as a purely structural method for reducing dimensionality using information contained within the dataset and preserving the meaning of the features. In this paper, the weighted interval-value fuzzy-rough attribute reduction algorithm is proposed for interval-value data. It will introduce IT2 into hybrid fuzzy-rough QuickReduct algorithm to deal with interval-value data. The “weighted” concept is not only enhancing prior knowledge, and also reduces unknown information effect.
