DISCUS

Yesterday I was visiting Monmouth College to participate on the Darwinpalooza which commemorates the 200th anniversary of Charles Darwin’s birth and the 150th anniversary of the publication of On the Origin of Species. After scratching my head about about what to present, I came out with quite a mix. You will find the abstract of the talk below, as well as the slides I used. Abstract: One hundred and fifty years have passed since the publication of Darwin’s world-changing manuscript “The Origins of Species by Means of Natural Selection”. Darwin’s ideas have proven their power to reach beyond the biology realm, and their ability to define a conceptual framework which allows us to model and understand complex systems. In the mid 1950s and 60s the efforts of a scattered group of engineers proved the benefits of adopting an evolutionary paradigm to solve complex real-world problems. In the 70s, the emerging presence of computers brought us a new collection of artificial evolution paradigms, among which genetic algorithms rapidly gained widespread adoption. Currently, the Internet has propitiated an exponential growth of information and computational resources that are clearly disrupting our perception and forcing us to reevaluate the boundaries between technology and social interaction. Darwin’s ideas can, once again, help us understand such disruptive change. In this talk, I will review the origin of artificial evolution ideas and techniques. I will also show how these techniques are, nowadays, helping to solve a wide range of applications, from life science problems to twitter puzzles, and how high performance computing can make Darwin ideas a routinary tool to help us model and understand complex systems. ...

DITA and ALG at NCSA have joined forces with the DISCUS team to enter the 2007 VAST contest. You can find a podcast of the entry to the contest here, and a description of the VAST contest below. Visual Analytics is the science of analytical reasoning supported by highly interactive visual interfaces. People use visual analytics tools and techniques to synthesize information into knowledge; derive insight from massive, dynamic, and often conflicting data; detect the expected and discover the unexpected; provide timely, defensible, and understandable assessments; and communicate assessments effectively for action. The issues stimulating this body of research provide a grand challenge in science: turning information overload into the opportunity of the decade. ...

This 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. A follow up presentation with further details is also available here.

I 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). ...

September 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 :). ...
