## Package org.apache.mahout.fpm.pfpgrowth.fpgrowth

Class Summary
FPGrowth<A extends Comparable<? super A>>: Implementation of PFGrowth Algorithm with FP-Bonsai pruning
FPTree: The Frequent Pattern Tree datastructure used for mining patterns using `FPGrowth` algorithm
FPTreeDepthCache: Caches large FPTree `Object` for each level of the recursive `FPGrowth` algorithm to reduce allocation overhead.
FrequentPatternMaxHeap: keeps top K Attributes in a TreeSet
LeastKCache<K extends Comparable<? super K>,V>
Pattern: A in FPGrowth is a list of items (here int) and the support(the number of times the pattern is seen in the dataset)
