Firstly, the sample matrix wasnormalized through the normalization of sample data. Secondly, a fuzzy equivalencematrix was constructed by using fuzzy clustering method based on thenormalization matrix, and then the fuzzy equivalence matrix was applied as thebasis for dynamic clustering. Finally, a series of classifications were carried out onthe mass data at the cut-set level successively and a dynamic cluster diagram wasgenerated. The experimental results show that using data fuzzy clustering methodcan effectively identify association rules of data sets by multiple iterations ofmassive data, and the clustering process has short running time and good robustness.Therefore, it can be widely applied to the identification and classification ofassociation rules of massive data such as sound, image and natural resources.展开更多
