The Algorithm of Mining Frequent Patterns Based on Vertical Bitmap
By utilizing vertical bitmap diagram map the database of transaction, a new NBFP-Tree structure based on bitmap diagram is raised. As a result we create a new maximal frequent pattern mining algorithm named NBFP-mine. This algorithm does not generate any candidate sets. By depth-first traversing through the NBFP-tree once, we can obtain the maximal frequent item-sets from the NBFP-Tree structure. The efficiency and accuracy of the algorithm are effectively demonstrated both in theory and experiments.
