Class Summary |
FPGrowth<A extends Comparable<? super A>> |
Implementation of PFGrowth Algorithm with FP-Bonsai pruning
Generic parameter A is the object type used as the cell items in a transaction list. |
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 |
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) |
