Thanks to everyone for all their hard work in making these releases happen.

February 2011 TriHUG slides posted

grant_ingersoll — Wed, 02 Feb 2011 23:44:11 +0000

I put my slides up from last night’s TriHUG talk on Apache Mahout on my slideshare account.

TriHUG: Apache Mahout

grant_ingersoll — Mon, 31 Jan 2011 13:04:26 +0000

I will be speaking tomorrow night at the Triangle Hadoop Users Group on Apache Mahout, hosted by Bronto Software. This will be an introduction to both Mahout and machine learning, but we will also look at how Mahout uses Hadoop in a particular algorithm. To learn more, see Triangle Hadoop Users Group.

Next up, ApacheCon!

If you missed the Lucene Revolution conference, especially the training on Apache Solr and Lucene, don’t worry. You won’t have to wait long for the next round, both Erik Hatcher (co-author of Lucene In Action) and I will be giving trainings at ApacheCon in Atlanta in November.

To learn more and sign up, see:

There will also be almost two days of talks on Lucene, Solr, Mahout and friends.

Apache Mahout catching on in Academia

grant_ingersoll — Tue, 31 Aug 2010 14:45:44 +0000

It’s back to school time and for those with academic interests in machine learning, it’s great to see Apache Mahout is catching on in academic circles, in addition to commercial circles. The interest is no doubt due to its open code, active community and focus on real world machine learning techniques. The first class based on Mahout that I am aware of was Mahout committer Isabel Drost’s class at TU Berlin. Of course, with all due respect to Isabel, she is a bit biased towards Mahout; so I was pleasantly surprised when Dr. David Grossman (See his excellent Information Retrieval: Algorithms and Heuristics (The Information Retrieval Series)(2nd Edition) book, for starters) from the Illinois Institute of Technology contacted me last spring about putting together a class on Mahout for the fall at IIT. Well, that class has finally come to fruition as CS 422: Data Mining Course Homepage and it looks to have nice coverage of the things near and dear to Mahout: clustering, classification, pattern mining and recommenders along with the requisite theoretical underpinnings.

I’ve also heard from a few other Professors who are working on adding Mahout to their coursework and would love to hear from more. So, if you are teaching a class on machine learning and interested in Mahout for teaching purposes, either let me know (gsingers@apache.org) or drop a line to the Mahout community mailing list: user@mahout.apache.org.

Upcoming Apache Lucene and Solr public trainings

grant_ingersoll — Mon, 30 Aug 2010 15:33:02 +0000

Erik Hatcher and I are once again offering our Lucene and Solr training classes, but this time there are two opportunities to participate. The first will be at Lucene Revolution on October 5 and 6. The second is on Nov. 1st and 2nd at ApacheCon NA 2010. Both classes are designed to get people up to speed on either Lucene or Solr as quickly as possible. If you have any questions, feel free to drop me an email at trainer@lucenebootcamp.com.

Next Meeting: Triangle HUG

grant_ingersoll — Thu, 19 Aug 2010 12:58:44 +0000

The next TriHUG meeting has been announced: Sept. 14. There will be two speakers:

Wei Wei on Practical Hadoop Security and Me on Hadoop and Lucene and Solr.

For more info and to RSVP, see Triangle Hadoop Users Group.

Triangle Hadoop Users Group First Meeting

grant_ingersoll — Thu, 08 Jul 2010 17:23:22 +0000

I’m pleased to announce a few of us Apache Hadoop users in the Triangle (Raleigh, Durham, Chapel Hill North Carolina) have finally reached critical mass since I sent out an email over a year ago to the Hadoop mailing list asking for interested people. We’ve found a place to meet and discuss the Hadoop ecosystem, so please join us at our first meeting on July 20th at Bronto Software. Find out more details at: Triangle Hadoop Users Group

We are starting with some introductory talks, but we will no doubt get much deeper very quickly. If you’d like to give a talk or sponsor or just attend, drop on over to the TriHUG website for more information.

Apache Mahout’s got a brand new look

grant_ingersoll — Mon, 28 Jun 2010 12:53:37 +0000

Thanks to committer Robin Anil for putting together Mahout’s shiny new website: Apache Mahout:: Scalable machine-learning and data-mining library.
