IDAL members attended last April to the SSCI2011 conferences on Computational Inteligence, that was held in Paris
Category: Conference (Page 4 of 4)
IDAl members have recently attended the IJCNN 2010, held in Barcelona in July 18-23. This conference was jointly held with FUZZ-IEEE 2010 and IEEE CEC 2010, with the generic name World Congress on Computational Intelligence WCCI 2010.
José D. Martin has collaborated in the organization of a special session in Computational Intelligence for Bioinformatics, and he also was the chairman in the session “Classification and Clustering II”.
The IDAL presentation was performed by José D. Martín, and it was entitled “Feature selection using ROC curves on classification problems”.
IDAl members also met some presonalities in Machine learning, like the renowned Professors Erkki Oja and Sun-ichi Amari and established contact with several researchers in different fields.
Abstract: Partition clustering is sensitive to initialisation. Moreover, it is not always clear whether a unique best solution exists for a given practical problem. A methodology is presented for mapping the space of partition clusters, from which to sample reproducible cluster solutions with good separation measured by second-order statistics and with stability to repeated initialisations. The cluster solutions are reproducible in the sense that multiple independent re-samplings of the initial conditions will return substantially identical partitions, for the same data and clustering algorithm. An extension of the methodology is proposed to reproducibly define a hierarchical tree of cluster solutions for increasing cluster number. The method is evaluated with synthetic data and applied to a previously studied protein expression dataset.
Dr. Terence A. Etchells gave on April 15th 2010 a conference at IDAL facilities titled “Rules from Data via a Neural Network. Orthogonal Search-based Rule Extraction (OSRE)“. Prof. Etchells was visiting IDAL for 5 days, although visit was unintentionally extended due to air space closed because of volcanic ash. IDAL members thank professor Etchells his excelent dissertation.
