Uncertain Data Flow Mining Algorithm Based on Hybrid Model

Sliding window technique in data mining algorithm is one of the most widely used technology, considering the characteristics of uncertain data stream and SRUF-mine algorithm in the profile structure tree storage potential, the expectations of frequent itemsets will appear deviation, on the basis of the joined the error factor to improve the accuracy.In SRUF-mine algorithm on the basis of the combination of data stream processing technology, is proposed based on hybrid model of uncertain data flow algorithm for mining frequent itemsets - DSUFIM-mine is presented. Experiments show that DSUFIM-mine algorithm has high accuracy and practical significance.
