Re: Mahout vectors/matrices/solvers on spark

Well one fundamental step to get there in Mahout realm, the way i see it, is to create DSLs for Mahout's DRMs in spark. That's actually one of the other reasons i chose not to follow Breeze. When we unwind Mahout DRM's, we may see sparse or dense slices there with named vectors. To translate that i

Re: Mahout vectors/matrices/solvers on spark

You're right on that - so far doubles is all I've needed and all I can currently see needing.  ​I'll take a look at your project and see how easy it is to integrate with my Spark ALS and other code - syntax wise it looks almost the same so swapping out the linear algebra backend would be quite

Re: Mahout vectors/matrices/solvers on spark

I think that contrib modules would be very interesting. Specifically, good Scala DSL, pig integration and so on. On Mon, Jun 24, 2013 at 9:55 PM, Dmitriy Lyubimov wrote: > On Mon, Jun 24, 2013 at 1:46 PM, Nick Pentreath >wrote: > > > That looks great Dmitry! > > > > > > The thing about Breeze

Hi, I am Samiran. I participated in 3 day local workshop at ICFOSS ( http://community.apache.org/mentoringprogramme-icfoss-pilot.html). I am looking forward to contribute to Mahout project. I am Java beginner and learning it fast. My interest domain is data mining and I am familiar with clustering

Re: Mahout vectors/matrices/solvers on spark

That looks great Dmitry!  ​The thing about Breeze that drives the complexity in it is partly specialization for Float, Double and Int matrices, and partly getting the syntax to "just work" for all combinations of matrix types and operands etc. mostly it does "just work" but occasionally not.

Re: Mahout vectors/matrices/solvers on spark

Yeah, I'm totally on board with a pretty scala DSL on top of some of our stuff. In particular, I've been experimenting with with wrapping the DistributedRowMatrix in a scalding wrapper, so we can do things like val matrixAsTypedPipe = DistributedRowMatrixPipe(new DistributedRowMatrix(numRows,

Re: Mahout vectors/matrices/solvers on spark

Ok, so i was fairly easily able to build some DSL for our matrix manipulation (similar to breeze) in scala: inline matrix or vector: val a = dense((1, 2, 3), (3, 4, 5)) val b:Vector = (1,2,3) block views and assignments (element/row/vector/block/block of row or vector) a(::, 0) a(1, ::) a(0
