基于三支决策的自适应粗糙集近似
Adaptive rough set approximation based on three-way decisions
摘要
Abstract
An adaptive learning method of rough set approximation based on three-way decision-theory is discussed, and an algorithm for attribution evaluation function is also established. What's more, in order to make the relationship clearer between objects and attributes through the process of rough set approximation, the concept of description set is intro-duced. Then a given target concept can be approximated under the known attribute evaluation function. Finally, the pro-cess between the new approximation method and cognition is compared, and their similarities are analyzed as well. With the benefit of the inspiration from the approximation process, the efficiency of cognition can be improved to some extent.关键词
