I am looking into the code in the FPGrowth class, I have some questions:
1. What does the variable conditionalOfCurrentAttribute In the growthBottomUp method and the growthTopDown method means? 2. the header table is traversed in the fpGrowth method, why is it traversed again in the growth method? By the way the FPGrowth implementation is very different from the paper Efficient Incremental Mining of Top-K Frequent Closed Itemsets Which can be downloaded from http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.106.3693&rep=re p1&type=pdf Anyone can give me some documents to help me understand the implementation? Thanks! Sincerely
