Quickly calculating reduct: An attribute relationship based approach

作者：

Highlights：

• An acceleration mechanism for attribute reduction is considered from the perspective of attribute relationship.

• The dissimilarity and similarity between attributes are introduced into the framework of quickly calculating reducts.

• Our proposed approaches can reduce the elapsed time of deriving reduct.
