Here's the official Mahout website. It looks like a community, like a Wiki community.

They have the following:

- User and Item based recommenders
- Matrix factorization based recommenders
- K-Means, Fuzzy K-Means clustering
- Latent Dirichlet Allocation
- Singular value decomposition
- Logistic regression based classifier
- Complementary Naive Bayes classifier
- Random forest decision tree based classifier
- High performance java collections (previously colt collections
- A vibrant community

Wondering who use Mahout, in which languages these algorithms are written (some of them seem very technical), and whether they'd be interested in integrating some of my algorithms:

- clustering and taxonomy for massive data sets
- Hidden decision trees
- Fast combinatorial feature selection
- Log file summarizing (Map-Reduce framework)

How do you contact them? What are the requirements to be accepted?

It's written in Java. There is a wiki for Python. Anyone interested in creating a Perl repository? If yes contact me at [email protected]
