Error while trying to use mahout/examples/bin/build-reuters.sh
Hello,
I try to run the Dirichlet example via this shell:
mahout/examples/bin/build-reuters.sh
I'm fairly new to Mahout and to Maven and I think something is wrong with
dependencies and probably with the repositories I should add to my
settings.xml ?
Thanks for your help!

Re: Clustering users
Posted by Sean Owen <sr...@gmail.com>.
I believe those jobs will internally create whatever they need along
the way, including user vectors if needed.
To just create them by themselves, you could run ToItemPrefsMapper and
ToUserVectorReducer from org.apache.mahout.cf.taste.hadoop.item.

Generally, you want to do a bit of projection on these data before
clustering.
One option is random projection. This maps each item to a sparse binary
vector based on a few independent hashes of the original item id. This
gives you are moderate dimensional vector to do clustering in (say 100,000
dimensions instead of the original gazillion).
The other option is SVD. With a gazillion columns in your matrix, you may
want to do the random projection trick first and then do an SVD. The
resulting 10-30 dimensional representation for users is likely to cluster
much better than the original data.
The random projection you would need to implement. The SVD can be done once
you have Mahout vectors to play with.

Re: Clustering users
Posted by Jeff Eastman <jd...@windwardsolutions.com>.
In general, you will need to write a custom Mapper that accepts whatever
format your user data is in and converts it to Mahout Vectors in a
preprocessing job. Look at the Synthetic Control clustering jobs in
/examples/ for an instance in the Canopy package. Once you have your
input data as a sequence file [key=Text(userId);
value=VectorWritable(prefs)] you can run the KMeansDriver - or any of
the other clustering jobs - on it directly.
The user vectors would indeed be constructed out of the M items for each
user e.g. user-i = [item-i0, item-i1, ..., item-NM]. If you wrap the
user vector in a NamedVectorWritable you can attach the userId as the
vector name and it will pass through the clustering and out the end in
the clusteredPoints. Just map your boolean preferences to 0 and 1; a
ManhattanDistanceMeasure would be a good place to start too.
When you are done, you will have a 'clusteredPoints' directory with more
sequence files [key=IntWritable(clusterId); value=VectorWritable(prefs)]
which you can feed into subsequent processing or output with the
ClusterDumper. Have fun and let me know if you need any more hints.

Re: RecommenderJob output
Posted by Sean Owen <sr...@gmail.com>.
The values are entries in the final recommendation vector. They don't
have a good interpretation by themselves, but larger values should
mean better recommendation. So the recommendations are ordered by this
value. It's included just in case it is useful. In other recommender
systems (like .pseudo), this would be the actual estimated preference.
However I don't immediately see why the result would be negative
infinity, ever. I'd have to look into that.

Great info. No, I'm not looking into having multiple active processes trying to update it. It's more of a single worker process that needs to update the "model" as new data becomes available (every few hours, days,... depending on the customer needs). Ideally I should be able to tell which users were affected so only their recommendations would end up being updated back to Solr. I am getting closer to the end of the evaluation process of Mahout and will soon proceed with the implementation, at which point I hope I'll be able to provide better feedback and contribute more.
On a different thread - I have a high level / best practices question: When doing clustering or classification with large datasets - is the expectation that the algorithms would run on the whole data set available or a (carefully selected) sub set i.e. the training model. I'm interesting in the "model" deployed in production, not just for the purpose of training.
If the answer is - a sub set - what is usually a good size relative to the full data set and how do people approach this in order to get a representative smaller set?

Can you update it while it's running? Not really. It's a multi-phase
batch job and I don't think you could meaningfully change it on the
fly.
Do you need to run the whole thing every time? No, not at all. Phase 1
(item IDs to item indices) doesn't need to run every time, nor does
phase 3 (count co-occurrence). It's OK if these are a little out of
date. Phase 2 is user vector generation; while I didn't write any
ability to simply append a new user vector to its output, it's easy to
write. So you don't have to run that every time.
Phase 4 and 5 are really where the recommendation happens. Those go
together. You can limit which users it processes though with a file of
user IDs, --usersFile.
I'd say the core job is nearing maturity -- think it's tuned and
debugged. But these kind of practical hooks, like being able to
incrementally update aspects of the pipeline, are exactly what's
needed next. I'd welcome your input and patches in this regard.

One question on the recommendation lifecycle: once a RecommendationJob is being run with the intermediate/temp model being created what is the process of maintaining it? Can I update it or parts of it to reflect new data?
For example if I have a new user or new preferences for an existing user that I want to compute recommendation for can I do that by incrementally update the internal model and regenerate only recommendations for the user that I'm interested in?

There were actually a few hijacks on this thread, AFAICT. This one, the Safari one and the Clustering one. If you look at the full headers, you'll see either a common message-id or a common reply-to header, which causes some (but not all) mail clients to automatically group those threads.

Clustering users
Posted by First Qaxy <qa...@yahoo.ca>.
Hello,
Just started looking into clustering - KMeansDriver - and have a question on clustering users. Considering that overall I have a huge number of items, how do I create the vectors for the users? Is there any code in Mahout to support that or do I need to write it by turning all userN, itemM pairs (boolean pref) into a userN vector ? I'm not exactly sure - how would this vector look like? Also at the end of the clustering I need to show the original user. Is that possible?Any pointers would be great. Thanks,-qf

Yes that sounds like a symptom of the last issue I fixed up. I just
committed a similar fix.
Basically wherever we did...
String path = parent + "/foo"
and it became
Path path = new Path(parent, "/foo")
the "/" needs to go away. Perhaps surprisingly, in something like the
above, parent gets ignored.

Yep, I'm running trunk.
However, I *think* that when I try to build utils (via mvn -B) it's actually
pulling mahout-core/mahout-test jars from a repo which seems strange to
me...

Re: Error while trying to use mahout/examples/bin/build-reuters.sh
Posted by Sean Owen <sr...@gmail.com>.
I am indeed suspicious that among the extensive changes I made, that
some assumption got violated somewhere, about who's creating which
files where. It may have been necessary to make the tests happy.
If that's the case I hope it's isolated, and should be easy to fix.

Re: Error while trying to use mahout/examples/bin/build-reuters.sh
Posted by Florent Empis <fl...@gmail.com>.
Hi,
It might help for the build part, but probably won't fix the 2nd issue?
The / is not writeable on most systems so creation of
/tokenized-documents/_temporary
will still fail?

Hi Florent,
I successfully ran the new build-reuters.sh before I committed it this
morning, so I suspect you must have some other problem in your system.
Have you tried deleting your Maven repository (.m2) and doing a full mvn
clean install?

Re: Error while trying to use mahout/examples/bin/build-reuters.sh
Posted by Florent Empis <fl...@gmail.com>.
Hi,
I've seen the commit from Robin this afternoon so I gave it another try.
Using the new shell I still run into a few problems
At first, in order to satisfy a dependency to slf4j I've had to add the
following to examples/pom.xml (once again I'm not a maven expert, so this
may not be the correct way to do it)
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-nop</artifactId>
<version>1.5.8</version>
<classifier>sources</classifier>
</dependency>
Then, after a succesful mvn -B
I've launched the shell:
florent@florent-laptop:~/workspace/mahout$ ./examples/bin/build-reuters.sh
It fails with the following error:
10/05/10 21:28:06 WARN mapred.LocalJobRunner: job_local_0001
