Re: Apache Mahout 0.6 Releasedgaurav singh 2012-02-07, 07:54
Hi,
When you say decision trees, you mean decision forest right? Is it possible to expect decision tree algorithm (C 4.5) to be in mahout, since the algorithm is pretty sequential in nature and won't be suitable for distributed processing.

+1 Congratulations to Shannon for a job well done. We now have a 0.6
release and can begin to concentrate on the plan and issues for a 0.7 release. On 2/6/12 2:19 PM, Shannon Quinn wrote: > Apache Mahout has reached version 0.6.

Thank you for the wonderful work!
Does the new release support built-in MapReduce for the User-based Recommenders?

No user-based approach there, no.

Yes, congrats to all concerned, really great seeing this moving along :) Meanwhile, the homepage still says "Latest release version: Mahout 0.5; Latest development version: Mahout 0.6-SNAPSHOT" ... is an update pending?

Hi,
For mahout's decision forest logic, each machine node makes trees sequentially as you think. But we can get trees for a forest parallelly.
