Subject Power iteration clustering
Date Sun, 24 May 2015 03:09:22 GMT

What was the motivation to write power iteration clustering using graphx
and not a vector matrix multiplication over similarity matrix represented
as say coordinate matrix ?

We can use gemv in that flow to block the computation.

Over graphx can we do all k eigen vector computation together because I
don't see that in a vector matrix multiply flow ? On the other side vector
matrix multiply flow is generic for kernel regression or classification
