WebPFP distributes the work of growing FP-trees based on the suffixes of transactions, and hence more scalable than a single-machine implementation. We refer users to the papers for more details. spark.mllib’s FP-growth implementation takes the following (hyper-)parameters: minSupport: the minimum support for an itemset to be identified as frequent.
