[jira] [Commented] (MAHOUT-157) Frequent Pattern Mining using
Parallel FP-Growth
[ https://issues.apache.org/jira/browse/MAHOUT-157?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13979725#comment-13979725 ]

----------------------------------------------
Hey Robin, Regarding your comment dated 07/Sep/09 06:32
I know its been a long time since the post, but i actually wanted to use pfpgrowth on mahout without closing of the itemsets.
For it, I downloaded your source and tried to interpret it and initially i thought that the issue was in FPGrowth.generateSinglePathPatterns() as you are adding the entire conditional FP Tree in the frequentPatterns.
For eg: if the conditional fp tree had [f:3 c:3 a:3 m:3], then this method makes the pattern [f,c,a,m | 3] and inserts it into the FrequentPatternMaxHeap. I thought the problem was not generating all the combinations here but it seems that i couldn't able to understand the code correctly.
Could you please just lead me to the point(s) or code snippet(s) where the closure is being performed so that i could test on how to remove this closure.
Thanks,
Aman
