Last call for participation to the Lanscape Contest

The landscape contest is a research competition aimed at finding out the relation between data complexity and the performance of learners. Comparing your techniques to those of other participants may contribute to enrich our understanding of the behavior of machine learning techniques and open further research lines.
The contest will take place […] Continue reading

Facetwise analysis of XCS for problems with class imbalances

by Albert Orriols-Puig, Ester Bernadó-Mansilla, David E. Goldberg, Kumara Sastry, and Pier Luca Lanzi. IEEE Transactions on Evolutionary Computation, doi=10.1109/ TEVC.2009.2019829, [Publisher site].

Michigan-style learning classifier systems (LCSs) are online machine learning techniques that incrementally evolve distributed subsolutions which individually solve a portion of the problem space. As in many machine learning systems, extracting accurate models […] Continue reading

Save analysis of your results

Over the last few years, the increasing interest in machine learning has resulted in the design and development of several competitive learners. Usually, the performance of these methods is evaluated by comparing the new techniques to state-of-the-art methods over a collection of real-world problems.
In early days, these comparisons followed no standard, and qualitative arguments […] Continue reading

Beyond Homemade Artificial Data Sets in HAIS 2009

Find below the presentation of the paper Beyond Homemade Artificial Data Sets by Núria Macià, Albert Orriols-Puig, and Ester Bernadó-Mansilla in the 2009 Hybrid Artificial Intelligence Systems (HAIS’09).

This work aims at creating boundedly difficult problems for data classification whose complexity moves through different dimensions. For this purpose, this work proposes the use of a multi-objective […] Continue reading

Prof. Cirac interviewed about quantum physics and theory information

A few days ago, Prof. Cirac was interviewed in a Catalan TV channel about his work on quantum theory of information. Prof. Cirac explained the method based on quantum cryptography that he and his team have been developing during the last few years, which makes sure that the information can be neither intercepted nor decrypted. […] Continue reading
