Jianhua Ma · Journal of Shandong University · 2004
Introduces the concepts of granulation, degree of structure divergence, degree of nestle up, center divergence degree and margin divergence degree, etc, by rough sets theory and knowledge base theory. Paper puts forward distance formula between two data sets. Analysis the problem of classification and recognition of data sets though distance formula. This idea provides a powerful method to classify and distinguish data sets in computer.
