Daniel McEnnis updated MAHOUT-668:
----------------------------------
Attachment: Mahout-668-2.patch
I really think we should do knn. I have attached a 29 class patch implementing
this.
As originally designed, it is O(1) in memory usage, scales up to models the
size of a data node's harddisk, and has implementations for log files, text
files, tokenized text files, and Weka ARFF files.
