Mllib fp-growth

WebThe algorithm is described in Li et al., PFP: Parallel FP-Growth for Query Recommendation. PFP distributes computation in such a way that each worker executes an independent group of mining tasks. The FP-Growth algorithm is described in Han et al., Mining frequent patterns without candidate generation. 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.
