Mahout@TU WS 09/10

2009-09-09 23:08
Title: Mahout@TU WS 09/10


There is going to be a project/seminar course at TU Berlin on Apache Mahout. The goal is to introduce students to the work on a free software project, interact with the community and build production ready software.

Students will be given several potential tasks ranging from optimizing existing implementations, implementing new algorithms and (depending on their prior knowledge) improving, scaling and parallelizing existing algorithms.

Successful completion of the course depends on a number of factors: Interaction of the student with the community, ability to write tested (as in test-first-developed) code that performs well in a large scale environments, ability to show incremental development progress at each iteration, ability to review patches and improvements, usage of tools like SCM, Issue-tracker and mailinglists. Of course theoretical background - that is understanding existing publications as well extending their ideas is crucial as well.

If you are a student interessted in Mahout missing some course work, consider subscribing to the Mahout course at DIMA Berlin (linked below). Goal is that your work is to be integrated in one of the next releases, once the community is satisfied.

If you are a Mahout developer or user and have some issue that you consider suitable for a student to solve, please to provide your ideas.

GSoC at Mahout

2009-09-09 22:22
GSoC 2009 is about to finish: Final evaluations are through, most of the code submitted by Mahout's students has been committed to svn, code samples are on their way to Google.

In Mahout, we had three students joining the project: Robin working on an HBase based Naive Bayes extension and on frequent itemset discovery. David contributing a distributed LDA implementation. Deneche was working on a Random Forest implementation. All three of them have done great work during this summer, contributing not only code but valuable input on the project's mailinglists as well. As a result, all three of them have been given committer status by the end of GSoC.

Apart from three new additions to the code base, summer also brought quite some traffic to the user list - not only in terms of subscriptions but also in terms of developers contributing to the discussions online. Currently, it looks like the project is really gaining momentum, as also noted in Grant Ingersoll's post.

Discussions on the dev list on the future road map of Mahout clearly showed that the developers share the vision of a scalable, potentially distributed, stable machine learning library. That the focus should be on production ready code under a commercially friendly license instead of bleeding edge research implementations. Last but no least the goal is to build a lively, diverse community around the project to guarantee further development and user support.

2009 brought quite a few talks both in Germany as well as the US on the topic of Mahout (besides all the events on Hadoop, scalable databases and cloud computing in general) with an Apache Con US talk introducing Mahout in Oakland still to come.

Yesterday, a great article indroducing Apache Mahout with hands-on examples was published on IBM Developerworks by Grant Ingersoll. Check it out, if you want to learn more on Mahout, and Machine Learning in general.

First NoSQL Meetup in Germany

2009-09-09 18:58
On October 22nd 2009 the first NoSQL Meetup Germany is going to take place in newthinking store/ Berlin: http://nosqlberlin.de

Please submit your presentation proposals until September 22nd, accepted speakers will be notified soon after.

If you would like to sponsor the event, feel free to contact us: We would be very happy to provide videos after the event and free drinks for everyone during the event.

Hope to see you soon in Berlin.

Two days on Rügen

2009-09-06 15:50
Below: Sunday morning on Rügen, feet in the East Sea. It looks colder than it actually was: Air was about 17 °C, but the water was fine. At least for my feet.



Thanks to the colleague who sold two spare tickets for the Störtebecker Festspiele last Thursday and caused us to drive to isle Rügen yesterday afternoon.

Apache Con drawing closer

2009-09-04 06:47
By November I will be traveling to Oakland - for me it is the first Apache Con US ever. And the first Apache Con I will be giving a talk in one of the main tracks:



I will be presenting Apache Mahout, give an overview of the project, of our current status and explain which problems can be solved with the current implementation. The talks will conclude with an outlook to upcoming tasks and features our users can expect in the near future.

There is great news already: First commercial users like Mippin are explaining their experiences with Mahout.

Currently, I am looking forward to meeting several Mahout (and Lucene, Hadoop, Solr, ...) committers there. I met some at Apache Con EU already, but it's always nice to talk to people in person who before one only knew from mailing lists. Of course I am also looking forward to having time to review and write code. Hope to see you there.

Update: Flights booked.
