Ian H. Jarman and Terence A. Etchells, post-doctoral researchers of the Liverpool John Moores University (United Kingdom) will start a research stay with IDAL in the next weeks. The main topics of the joint research will include discrete clustering and graphical models, as well as some practical applications of those methods. Dr. Jarman worked on an integrated framework for risk profiling of breast cancer patients in his Ph.D, while Dr. Etchells worked on an efficient method for rule extraction from neural networks. Currently, both researchers are especially involved with the Public Health Research Centre of the LJMU, although their research also deals with theoretical aspects of Machine Learning algorithms and their applications beyond Public Health. IDAL has collaborated with the group of Statistics and Neural Computing of the LJMU, led by Prof. Paulo J. G. Lisboa since 2003.
