Hi All, I am using itemcf2 with cosine similarity. My dataset size is 2.5G and the matrix header is
%%MatrixMarket matrix coordinate real general 51700013 2274935 124393475
I am running cf as follows
$GRAPHCHIROOT/toolkits/collaborativefiltering/itemcf2 --training=$RECOHOME/userproductmatrix --minallowedintersection=5 --quiet=1 --nshards=1 --distance=4 --K=8 execthreads 24 membudgetmb 15360
It is running fine, but it is taking more than 2 days to compute product similarities.
Whether am I doing any thing wrong? How can we improve it's computation time?
