AN INCREMENTAL APPROACH FOR UPDATING APPROXIMATIONS IN DOMINANCE-BASED ROUGH SETS

摘要

Dominance-based rough set approach is dedicated to analysis of data with ordinal properties by the dominance relation. Approaches for incrementally updating knowledge is a hot topic in granular computing. This paper proposes an approach for dynamically updating approximations in dominance-based rough sets when adding or deleting objects in the universe. An example is employed to validate the proposed method.
