> FP-Growth Redundant patterns
> ----------------------------
>
> Key: MAHOUT-709
> URL: https://issues.apache.org/jira/browse/MAHOUT-709
> Project: Mahout
> Issue Type: Bug
> Components: Frequent Itemset/Association Rule Mining
> Affects Versions: 0.4, 0.5
> Reporter: Yarco Hayduk
> Assignee: Robin Anil
> Labels: fp-growth, frequent, parallel, pattern
> Attachments: SixTransactions.dat, bresult-new.txt, dumpedPatterns,
> patterns-converted.txt
>
>
> The algorithm outputs more patterns that it is needed.
> I have tested Mahout's PFP-Growth algorithm with the
> http://www.borgelt.net/fpgrowth.html FP-Growth implementation. This
> implementation has an option to generate closed patterns too.
> When I filtered out the sub patterns from the output of Parallel FP-Growth I
> arrived to the same result, as in http://www.borgelt.net/fpgrowth.html
> Succinctly, you are not outputting closed items
> I am attaching the dummy DB along with the output of both algorithms
