Frequent Pattern Growth (FP-Growth) Algorithm Outline

We have introduced the Apriori Algorithm and pointed out its major disadvantages in the previous post. In this article, an advanced method called the FP Growth algorithm will be revealed. We will walk through the whole process of the FP Growth algorithm and explain why it’s better than Apriori.

WebConstruct a Conditional FP Tree, formed by a count of itemsets in the path. The itemsets meeting the threshold support are considered in the Conditional FP Tree. Frequent … WebThe FP-tree is mined as follows. Start from each frequent length-1 pattern (as an initial suffix pattern), construct its conditional pattern base (which consists of the set of prefix paths in the FP-tree co-occurring with the suffix pattern), then construct its conditional FP-tree, and perform mining recursively on the tree.
