The Point Fencing Club 2006 Calendars
18 December 2005The calendars for 2006 arrived to the club last Friday during the 3rd Friday Foil Fight. Check them out! This year they come in a cool landscape layout instead of the 2005 portrait one.
A simple UMDAc implementation in Java
6 December 2005Cecilia Oversdotter is working on an adaptation of active interactive genetic algorithms (some papers can be found here and here) to her work on speech synthesis and perception of emotions in expressive storytelling. She needs a version of the active interactive genetic algorithm that works on continuous domains. For that reason I coded a version of UMDAc to replace the cGA currently used for discrete domains.
The Java implementation of UMDAc can be found here. In order to run it, you need to download the COLT toolkit . The code is distributed under GPL license.
Special issue on chance discovery (I)
1 December 2005The Journal of New Mathematics and Natural Computation is running the first ot two parts of a special issue on chance discovery (volume 1, number 3). The number, besides including two regular papers, contains the first part of this special issue. The journal page can be found here. The table of contents of this first part of the special issue is:
- Ruediger Oehlmann, Preface, page 371.
- Yukio Ohsawa, Data crystallization: chance discovery extended for dealing with unobservable events, page 373.
- Renate Fruchter, Yukio ohsawa, and Naohiro Matsumura, Knowledge reuse through chance discovery from an enterprise design-build enterprise data store, page 393.
- Calkin a. s. Montero and Kenji araki, Human chat and self-organized criticality: A chance discovery application, page 407.
- Ja-min Koo and Sung-bae Cho, Interpreting chance for computer security by viterbi algorithm with edit distance, page 421.
- Edward Tsang, Sheri Markose and Hakan Er, Chance discovery in stock index option and futures arbitrage, page 435.
A biography to read
1 December 2005Note to self (wishful thinking): Read as soon as possible Sir Arthur Conan Doyle’s biography by Daniel Stashower titled “Teller of tales: The life of Arthur Conan Doyle” published by Owl Books.
New blog for LCS and other GBML
30 November 2005Recently, Pier Luca Lanzi and I decided to upgrade the learning classifier systems site he used to maintain. We are greatly thankful to professor David E. Goldberg for kindly accept to host the site at IlliGAL. The new LCS and other GBML site is still in dippers, but do not worry, it will grow soon.
Probabilistic models of text and images
29 November 2005Recently I attended a talk by David Blei about probabilistic models of text and images. His thesis described probabilistic models for the retrieval, organization, and exploration of large information collections, casting this tasks as statistical queries. The abstract of his thesis ca be found here and the thesis itself here.
New club hours at The Point Fencing Club
28 November 2005As of December 1st, the club will no longer be open for free bouting on Thursdays. It will be opened on Thursdays only for clinics and special events as announced.
The new club hours are as follows:
- Monday, Tuesday, Wednesday, Friday: 6:00-9:30pm

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).
Machine learning & Statistical Learning in R
24 November 2005Torsten Horthorn maintains a page with a list of packages for machine learning and statistical learning in R.
