摘要
讨论了知识粗糙性的等价条件 ,证明了知识粗糙性与条件熵为零等价 ,同时还证明了互信息对知识粗糙性定义的偏序“较细”是单调下降的。从而揭示了知识粗糙性与条件熵的密切联系。
In this paper, the equivalent condition of Roughness of Knowledge are mainly discussed. prove that Roughness of Knowledge is equivalent to zerovalue of condition entropy and that mutual information are decreasing for the partial order finer on Knowledge.
