The current implementation of Random Forests looks good indeed. My
latest tests on NSL-KDD (http://nsl.cs.unb.ca/NSL-KDD/) shows similar
recognition rates such as those reported in the paper. After the
release of Mahout 0.3 (and the end of the current code freeze), I

The only example that actually uses watchmaker-swing is "Travelling
Salesman", mainly because it was a direct port of an existing
watchmaker example. And if I remember well, it does not actually use
JFreeChart...so I think it's safe to exclude it.

I used MerseneTwisterRNG a lot and noticed it somehow slows down the unit

As we talked about in the following discussion (A), I'm considering two ways to
implement a distributed map-reduce builder.
Given the reference implementation, the easiest implementation is the following:
* the data is distributed to the slave nodes using the DistributedCache
* each mapper load
Ok I'm going to add the tests...

Given it's my second participation, I have one advise : don't be shy to ask
about anything related to your project on this list (starting from now), its
the fastest way to learn about Mahout.

talking about Random Forests, I think there are two possible ways to actually
implement them:
The first implementation is useful when the dataset is not that big (<= 2Go
perhaps) and thus can be distributed via Hadoop's DistributedCache. In this
case each mapper has access to all the dataset a

Hi,
Im planning to participate, again, at GSoC and I want to do it, again, with
Mahout.
This year, lets make Mahout run over Amazon EC2. This means building the proper
AMIs, run some Mahout projects (the GA examples) over EC2, give feedback and
write simple, clear How-Tos about running a Mahout
It's a silly question :P but can you use Mahout without using Hadoop ? do you
mean that when having one single 'multi-core" machine, one can use Mahout alone
? (Ok, that's two silly questions)

Also, I'm not able to make my patchs delete files (or directories) when

It's not from the example code but from the example's test code. In this case
the example's tries to access a directory (wdbc) put into test/resources. The
content of test/resources is a

Sounds cool :)
I'll do the TSP part, but it may take some time because I'm a bit busy (PhD's
administrative stuff).
There are many available large TSP benchmarks, and it seems that there is a
common file format for them TSPLIB

I came across the following competition

It's about recommender systems, so I think it's a Taste stuff. The training
dataset consists of more than 100M ratings.

So I should hold off on committing change
You should run the "job" task in the examples directory (ant job), it will
generate a file (in examples/build) called
""apache-mahout-examples-0.1-dev.job", this is the jar (even if it ends with
.job) that contains both the examples and the core.

I did a fresh svn checkout of mahout and a got two hadoop jars !
hadoop-0.17.0-core.jar
hadoop-0.17.1-core.jar
I don't think we need both of them, do we ? :P

Now that the Class Discovery (CD) example is up and running, it's time to think
about what to do next. I already have some ideas, but I want to check with the
community first.
I see two possible ways ahead of me:
A.Enhance the (CD) example
a1. handle categorical attributes
a2. generate datase
I had to use an -Xmx 256m to get the tests to run without heap problems.
