Sean Owen commented on MAHOUT-24:
---------------------------------

Just doing housekeeping -- is this issue active, any chance it's still commitable? If it's reasonably complete, has some tests, and someone can imagine supporting it, commit. Otherwise let's archive this.

> This is a very skeletal but functional implementation for LWLR. It outputs n lines where n is the number of dimensions. ith line = sum(x[i]*x[ind]) where ind is the index of independant variable. So the actual gradient = 2nd line/1st line for the classical 2D.
> Contains a single small test case for demonstration.
