Thanks Pat and David,
I tried what you told me to do, but unfortunately is not working... I get the
following error when running the command:
./mahout clusterdump -i /user/Data-output/clusters-1-final -o analyze.txt
--evaluate true
ERROR common.AbstractJob: Unexpected true while processing
Hey all,
The *RecommenderEvaluator *has the option to choose how big your training
set is (and so choosing the test set size as well), but the
*RecommenderIRStatsEvaluator* does not seem to have this argument in its
*.evaluate()*-method. That's why I was wondering how the internals of the
- Is there a way to specify the train and test set like you can with the
*RecommenderEvaluator*?
No, though you can specify the evaluation percentage. This is because
of the logic of evaluation. The logic is to take away relevant items
and then make recommendations and see whether the
Hi Experts,
Here you can find simple piece of code which I wrote:

import java.io.FileReader;
import java.io.IOException;
import org.apache.hadoop.conf.Configuration;

I looked at the code and the -e shouldn’t need a value. The null pointer is
because of the other params. Unfortunately the help doesn’t say which params
are required. Looks like when it runs evaluation it needs the clustered points
and the distance measure should be the same as you used to
Hello Everyone,
I am recently working on a project, and I need to implement SVD
recmommender system. I am looking for a simple example to see how can I do
in mahout.
If you can share with me an simple example, it will me perfect.
Thank you in advance.

Hi,
I want to convert the output of cf module (als,svd) etc to csv. How do I
do the conversion?
I want to look at those latent features?
Thanks
Jamal
Hi Celal,
Refer to page 26 of the following document, which gives you some code snippet
on Mahout’s SVD.

Hi Jamal,
Maybe you can use getUserFeature() and getItemFeature() methods in
Factorization class to look at the latent features.
