I need to filter out Row 2 and Row 3, since {0,0,0,1,0} and {0,1,0,0,0} are subsets of the first row ({0,1,0,1,0}). So, as a results I should have only Row 1, since other two are redundant for me.
I don't know how else to explain my problem:) I am sure that there is some simple solution for that. Thanks!
P.S. Getting back to frequent itemsets - Maximal Frequent Itemsets is a frequent itemset for which none of its immediate supersets are frequent.

I need to leave only Item A Item B Item C, since it is maximal.
I have the following example:
Attr 1 Attr2 Attr 3 Attr 4 Attr 5
Row 1 0 1 0 1 0
Row 2 0 0 0 1 0
Row 3 0 1 0 0 0
