摘要：We propose a new reduct in the object-oriented rough set model called relative reduct. In the object?oriented rough set models, objects are treated as instances of classes, and illustrate structural hierarchies among objects based on is-a relationship and has-a relationship[2].We also introduced heuristic-filter base algorithm for finding reducts in the object-oriented rough set model. The reduct finding in the object-oriented rough set models suffer intense computation of discernibility function and positive regions. In order to improve the efficiency, in this paper, we develop a new computation model based on relative class dependency.
