----------------------------------
Hi,Owen.Thank you for your reply
my test data as follow (mahout version 0.4 , minsupport =2)
1 2 5
2 3
4 5
1 2 3
and the output as follow
1 ([2, 1],2)
2 ([2],3), ([2, 3],2), ([2, 1],2)
3 ([2, 3],2)
5 ([5],2)
Obviously,([1],2),([3],2) is missed
Is this a bug of the PFPG algorithm? How can i solve this problem?
thank you very much
