LCS & GBML Central: Community resource is now Online

27 March 2009

LCSweb was designed to allow researchers and those seeking to use Learning Classifier Systems within applications access to material on LCS and discussion between members of the LCS community. The site served this community since its was started by Alwyn Barry in 1997. Enhanced and maintained later by Jan Drugowitsch, LCSweb became a valuable community resource. The site was completely community-driven and allowed members to contribute to the content of the site and keeping it up to date.  Later on in 2005, I started “LCS and other GBML” Blog to cover a gap providing information information regarding the International Workshop on Learning Classifier Systems (IWLCS), the collection of LCS Books available, and GBML related news.Some of you may have realized that after Jan’s move to Rochester and Alwyn’s retirement from research activities, LCSweb has vanished. Will Browne took on himself to take LCSweb to Reading, but technical circumstances have made that move rocky despite his best efforts. Jan and Will however still have a local copy of LCSweb contents. After talking to Jan and Will, I proposed to merge LCSweb with the LCS and other GBML blog, and host the new site at NCSA where dedicated resources has been made available. Jan and Will agreed with the idea.  The current progress merging both sites can be summarized as  follows:Done:

• Resources for hosting are available at NCSA
• LCS and other GBML blog has been moved to NCSA (the old one will still be there for historic reasons and no updates will be made to it)
• A new name for the new merged site has been proposed (LCS & GBML Central)

In progress:

• Jan has taken upon himself to start slowly migrating the old content  into the new site (be patient, he is doing that manually for which we should be very thank full)

Besides, we have added two extra features to the site

1. Automatic aggregation of feeds (some of you may know this as you may have seen in so call planet sites). I just did a quick list of feeds that I knew and added them to the aggregator. Unfortunately, few of the sites of our community provided feeds, so I would encourage everybody to think about it. Why may this be important? The updates of those feeds go straight into LCS & GBML Central. That would make possible to create one stop place for information in the LCS and GBML community, and still maintain each separate member’s identity (you will see that when you click on an aggregated entry, you will be directed to the originators site)
2. Added forums to complement the LCS and GBML mailing list. Not to sure how useful will be, but at least it may help to jump in and ask questions (moderators volunteers more than welcome).

As mentioned above, the site is still on the building steps. LCSweb relevant content will be migrated slowly, but the main place holders are already there for your evaluation. Since this is a site for the community, we would love to hear about your feedback and ideas. As soon as new steps are conquered, we will keep you posted. Also, if you would like to help with the site, content transition, or know about  related feeds that should be aggregated please drop us an email, and  make this community your community.LCS & GBML Central can be reach at

IWLCS 2007 organizers

10 October 2006

Finally, we finished the pool process to get the organizers for IWLCS 2007. The next three volunteers that will be forming the organizing committee are:

• Bacardit, Jaume. University of Nottingham (UK)
• Bernadó Mansilla, Ester. Universitat Ramon Llull (Spain)
• Butz, Martin. Universitat Wurzburg (Germany)

Please join us welcoming them and encouraging them while taking the challenge of keeping IWLCS moving forward and expanding its reach. The advisory committee is now formed by

• Kovacs, Tim. University of Bristol (UK)
• Lanzi, Pier Luca. Politecnico di Milano (Italy)
• Llorà, Xavier. University of Illlinois at Urbana-Champaign (USA)
• Stolzman, Wolfgang. Daimler Chrysler AG (Germany)
• Takadama, Keiki. Tokyo Institute of Technology (Japan)
• Wilson, Stewart. Prediction Dynamics (USA)

IWLCS 2007: Call for organizers

10 July 2006

Dear colleagues,

The term for Tim Kovacs, Xavier Llorà, and Keiki Takadama as organizers of the International Workshop on Learning Classifier Systems is over. For the last two years we have organized the workshop and we have put together a book that covers 2003, 2004, and 2005 workshops (soon to enter the printing stage).

We have greatly enjoyed working with you all. Your friendship and help has motivated and guide us maintain alive the great effort that Pier Luca Lanzi, Stewart Wilson, and Wolfgang Stolzman started in 1999.

We would humbly put out this call for organizer for IWLCS 2007. For those of you that have been with us in the workshops, please, do not be afraid and volunteer. We would encourage you to get in touch with us before August 1st. Just sent and email to any of us (Tim Kovacs, Xavier Llorà, and Keiki Takadama). We would announce the next organizing committee by September 1st.

Thank you all for all the support during this two-year period!
Tim, Xavier, Keiki.
