Grant Ingersoll commented on MAHOUT-344:
----------------------------------------
Also, Ankur, do you have a reference to what your implementation is based off
of? I'm mostly wondering about the purpose of the keyGroups option. (I get
what it does at the syntax level, wondering about the purpose of it)

> Minhash clustering performs probabilistic dimension reduction of high
> dimensional data. The essence of the technique is to hash each item using
> multiple independent hash functions such that the probability of collision of
> similar items is higher. Multiple such hash tables can then be constructed
> to answer near neighbor type of queries efficiently.
