Abstract: Attribute fusion is an important applied characteristic hidden in packet sets, whose dynamic features come from its attribute fusion. By using internal packet sets structure and their dynamic features, the concept and structure of attribute inner fusion are proposed, and attribute inner fusion theorem is given. Then data fusion mining under the condition of attribute inner fusion is put forward. Moreover, the application of mining criterion with miningscreening of data fusion is shown.

Key words: inner fusion theorem, data fusion mining, mining criterion, packet sets, attribute inner fusion
