Thesis: Workshop
These two algorithms give our group a novel Data Structure Based on the pattern tree node set, which is more efficient than the traditional mainstream mining algorithms, you can override all the tasks related to frequent itemset mining, such as closed mode, longest mode and TOP-K mode.
