Hi there, I've have no experience with mahout but I know that it will solve my problem :) !
I've the following requirements: * No hadoop setup should be necessary. I want a simple approach and I know this is possible with mahout! * I have lots of points (~100 million) but also some RAM (32GB) * I know the clusters upfront via its center positions. * I need to assign every point to exactly one cluster. * Every cluster can have a different shape, area size and point count I've found: http://en.wikipedia.org/wiki/OPTICS_algorithm http://en.wikipedia.org/wiki/DBSCAN Both algorithms do not really pay attention to the fixed cluster center but I think I will start there. Is one of them implemented in mahout? Or do you have another idea or hint/link? Regards, Peter.
