WEKA vs Mahout

[First Qaxy <qa...@yahoo.ca>]

Hi all,
I've been asked and I'm trying to figure out what are the major differences between Mahout and WEKA concerning classification, clustering and assoc rules(PFPGrowth). My understanding so far is that:- Mahout supports unsupervised algorithms; WEKA also supports supervised through its UI.- Mahout scales much better while WEKA is memory bound.- Mahout is targeting developers directly; WEKA mainly data mining analysts.- WEKA supports automating detection of classification algorithms. does Mahout have something similar?- Anything important that I've missed?
If anyone can provide any insight that would be great. Thanks.

And at least one intangible that may or may not effect you depending on your needs/legal requirements: Mahout is Apache license, Weka is GPL.

Steven's comments are correct.  Weka has a larger collection of algorithms.
 Mahout is specialized
around scalable algorithms and scalable implementations.

Both packages support supervised and unsupervised algorithms.  Due to
scalability concerns, Mahout
does not have much in the way of agglomerative algorithms.

The highlights of Mahout right now are:

- very large scale SVD

- very large scale clustering

- scalable item-set detection

- the beginnings of very strong supervised classifiers for large features
sets x large training data

- decent underlying math library

- command line or API focus.  This is better than GUI focus for production
work.

Hi Qf,

It's worth considering that weka does make available an SDK so you can
extend or develop any algorithms. I've only used weka a little, I got the
impression it had more algorithms implemented. I could be wrong.
