Abstract: Some problems exists in FP-growth algorithm. It must recursively generate huge number of conditional FP-trees that requires huge volume of memory and costs a lot of time. In this paper. It uses matrix technology constrained sub-tree statistic frequent item sets and frequent item sets for data mining. Experimental result shows constraint sub-tree method with matrix technology is an efficient frequent pattern mining algorithm and it has a better time efficiency and space efficiency.
