Abstract: In order to quickly and effectively mine the 3D data set of the closed frequent itemsets, the paper proposes a data mining algorithm based on bitwise-based processing technology for 3D dataset——Bitwise-Data-Peeler(BD-Peeler). The algorithm makes the best use of the computer processing 32-bit data each time. The 3D data sets are stored by bits, so that it can increase the computational data each time in the 3D dataset. Experimental results show that it can quickly and efficiently mine the 3D data set of the closed frequent itemsets.

Key words: data mining, bitwise, 3D, constraint, closed frequent itemsets
