One possible explanation is that Mahout's FPG avoids reporting
patterns that are subsumed by others.
For example, if you have pattern [a, b, c] with support 3, you clearly
must also have [a, b], [b, c] and [a, c] with support = 3. Mahout
will not report any of those unless the support is
That seems to make sense. What do you mean by Mahout will not report any
of those unless the support is strictly greater
than 3. Is there a way for me to get all the patterns with support
strictly greater then a particular value?

Maybe it's easiest to give an example.
If you have input:
a b c
a b c d
ac d
a b c
You should expect Mahout to output (say, for support 2):
[a, b, c],3
[a, c, d],2
[a, c],4
You might also expect to see [a],4 or [a, b],3 but these are implied
by the other patterns. Note that [a, b] and
You were a real help Tom!
