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) |
