Re: Online machine learning on top of Hama BSP

It doesn't at all come into mahouts goals in anyway. all I am saying is such a library could reduce the risk of mahout moving to bsp or any other platform. And it is something non-map-reduce devs should try to push if they want ease of adoption. On May 28, 2012 11:12 AM, "Sean Owen" wrote: > Pers

Re: Online machine learning on top of Hama BSP

Personally -- note, personally -- I think that's a whole other project. I doubt Mahout will ever be anything but Hadoop-based, plus some sequential / pure Java bits. Or, put another way: that's way too much scope, to span a third (fourth?) computation model, in a project already sprawling. I think

Re: Online machine learning on top of Hama BSP

OK. So say mahout moves to using bsp. There are obviously risks you mentioned. if possible we need to be abstracting out the underlying execution. So an iterative algorithm should be written using a wrapper library that hides giraph, bsp and map reduce. That's something I think will be attractive

First of all we would like to mention that the ugly side in this thread was totally not intended. >From the options you gave, (c) would be a waste of time. The original intention of this thread was to politely check with Mahout community, if it would consider another programming model than Map-Red
