GECCO 2007 Hat Trick

12 July 2007

Yup, 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.

A simple UMDAc implementation in Java

6 December 2005

Cecilia 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.
