GECCO 2007 Hat Trick
12 July 2007Yup, never happened to me before. In John Koza’s words: Hat Trick, best paper in EDA track and two Bronze medals in the HUMIES competition. I just think that I was lucky and blessed to have the pleasure to work with such great people. It would not have happened if it wasn’t for them. Below you can find some of the presentations for the above Hat Trick, as well as some other work I presented on genetics-based machine learning.
An Overview of the DISCUS project
11 May 2007This presentation covers a general overview of the goals, origins, reasearch and tools currently available for the DISCUS project. For more information please visit the DISCUS project website.
Seattle and Tokyo
2 March 2007I am traveling again. This time Seattle was the first stop. NCSA was having a private sector partner meeting at Boeing. I was invited to present the work about DISCUS we are doing as part of the LINK alliance endeavor. And from Seattle to Tokyo where Yukio Ohsawa is organizing “Cubes for innovation: Information Systems for Design and Marketing”. The workshop sponsored by Tsukuba University and IEEE is being held today at University of Tokyo. I was invited to go over our work on DISCUS to create IT infrastructure to support innovative and creative processes. You can find the slides of my presentation above (you can also download the PDF).
One talk and a visit to UK
8 October 2006September 21 I was invited to give a talk at the Computer Science Department at UIUC. During the talk “Combating User Fatigue and Contradictions in Subjective-based Optimization Schemes” I reviewed some of the research I have been involved about active interactive genetic algorithms. The PDF of the presentation can be downloaded here. I also gave the same presentation to some of the members of the ASAP research group at the University of Nottingham. Natalio Krasnogor invited me for a visit. The main topic was latest advances on Pittsburgh LCS (Jaume Bacardit is working there on protein folding problems using Pitt-style LCS). I really enjoyed interact with people there—lots of challenges and interesting discussions. Oh, I almost forgot, the three days I was in Nottingham I saw the sun most of the day :).

Finally I am back up
17 September 2006Vacations were over quite a while ago, but things kept piling on my desk. Finally I succeeded clearing some big chunks of matters out of it. Enough that I could go to the Design Theory and Methodology (DTM 2006) conference in Philadelphia last Tuesday. The conference is held as part of the ASME International Design Engineering Technical Conferences (IDETC 2006) . Yan Jin invited me to join the panel he organized on Intelligent Systems and Innovation. I had a great time joining the DTM people, very interesting work—if you are interested on innovation and creativity.
Metadata stores and D2K
21 April 2006Today I gave a presentation for the ALG group in NCSA about metadata stores and how they can be used in D2K. The presentation has two parts. The first one covers and introduction to metadata in general with some examples. The second one, is about how to wrap a metadata store (Kowari, see the previous post here) and make it accessible in D2K. You can find the slides here.
Metadata stores
13 March 2006The DISCUS project has always supported that intuition that annotation capabilities are a must for knowledge and information exchange. For instance, imaging that you are analyzing the KeyGraph generated from a particular discussion (here you can find an example). You may want to enrich such graph with your analysis, comments, or related information. Basically, you want to add metadata to the KeyGraph. If such a capability is available, a whole new bunch of information will need to be efficiently stored to allow, not only fast and easy retrieval, but allow analysis of the added metadata.
The Kowari project is an Open Source, massively scalable, transaction-safe, purpose-built database for the storage, retrieval and analysis of metadata. It provides a simple query language to interact with the metastore (iTQL). If you are familiar with SQL the resemblance will help you get up to speed very fast. The design is oriented to efficiently manage large volume metadata. Informal tests from Joe Frutelle, a NCSA colleague, have convinced me that this metastore can be the way to go for storing the large volumes of metadata that annotation may produce in DISCUS.
DISCUS as open source code?
24 November 2005Recently Jack Park from Iris Semantic Network left a comment asking, among other things, if DISCUS was going open source. This is an interesting question. DISCUS is currently under two patent pending processes. However, the current policies at NCSA, one of the DISCUS partners, is to push toward open source. We are currently finishing a first release of DISCUS International with support for English and Japanese. When it passes the release quality standards, some parts of DISCUS will be disseminated, may be as open source code. This is, however, an issue that needs to be ultimately discussed with the Office of Technology Management (the university office handling the DISCUS patent process).
The compact classifier system: Motivation, analysis and first results (Presentation)
5 September 2005This is the presentation for the initial paper on the compact classifier system published in CEC 2005 (Edimburgh., Scotland, September 2005). The paper may be find here (PDF, 0.7Mb) and the presentation slides here (PDF, 1Mb).
