That's a good question; I could imagine it being much more efficient if kept in a BlockMatrix and using BLAS2 ops. On Sat, May 23, 2015 at 8:09 PM, Debasish Das wrote: > Hi, > > What was the motivation to write power iteration clustering using graphx > and not a vector matr

Power iteration clustering

2015-05-23 Thread Debasish Das
Hi, 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
