Just updated to today's Mahout trunk and everything works for me. Can you send me the error?
Sebastian, do we really want this limit in RowSimilairty? It will not be applied to [B'A] unless you also do a mod to give us RowSimilairty on two matrices. Now that would be very nice indeed… On Aug 3, 2013, at 9:48 PM, B Lyon <[email protected]> wrote: Hi Pat I was going to just play with building the sold-recommender stuff in its current wip state and noticed a compile error (running mvn install) I think because the 0.9 snapshot has some changes on July 30th http://svn.apache.org/viewvc?view=revision&revision=1508302 Basically, back on June 18, Ted noticed that the downsampling might not be being done at the right place to actually avoid overwork due to "perversely prolific users" (thread is here: http://web.archiveorange.com/archive/v/z6zxQatCzHoFxbdLF0of), and someone else (Sebastian Schelter) has already acted on this (July 30) to move the downsampling to somewhere else (Mahout-1289 - https://issues.apache.org/jira/browse/MAHOUT-1289), which (among other things) removes the SAMPLE_SIZE static variable from ToItemVectorsMapper. I don't know how the general changes affect what you were setting up/playing with. Let me know if I've missed something here. -- BF Lyon http://www.nowherenearithaca.com
