Two Msc students from CIRG, Gary Pampara and Andrich van Wyk, visited the University of Pernambuco in Recife, Brazil, over the first week of December. Their visit was hosted by Prof. Fernando B. Lima Neto and Prof. Carmelo J. A. Bastos Filho. Gary and Andrich ran a workshop focused on CIlib and its use for research purposes. Over the course of their stay, they also paid a visit to the Federal University of Pernambuco.

Title: Practical aspects of neural network applications in experimental physics
Summary: Contemporary experiments in high energy and nuclear physics are characterized by very high rate of produced data and their extremely sophisticated structure, while the wanted physical effects are hidden in a huge background exceeding useful information by many orders of magnitude. Experimental data processing led to many multiparametric problems, so one of the effective ways to solve them is an approach that relates to artificial neural networks (ANNs). However almost all practical attempts to apply ANNs met the problem of transforming experimental data to make them suitable for input to ANNs. In this talk some examples from the practice of the Joint Institute for Nuclear Research are given to show how to choose the ANN type and structure and how to prepare data to deal with them. These examples include various problems of pattern recognition, hypothesis testing and classifying solved by applying feed-forward and recurrent neural networks.

CIRG has entered into an official research collaboration agreement with the University of Cypress. The research project is supported with funding provided by the Research Promotion Foundation in Cypress. Pavlos Antoniou will be working towards his doctorate under the supervision of Prof. Andreas Pitsillides of the University of Cypress, with co-supervision by Prof. Andries Engelbrecht at CIRG, and Dr. Tim Blackwell from Goldsmiths, University of London. The focus of the work is on congestion control in autonomous decentralised networks, with the use of swarm-based algorithms.

Prof. Andries Engelbrecht today presented a plenary talk at the 8th International Conference on Hybrid Intelligent Systems (HIS 2008), taking place in Barcelona, Spain. The talk, entitled "CIlib: A Component-based Framework for Plug-and-Simulate Hybrid Computational Intelligence Systems", gave an overview of CIRG's CIlib initiative, and focussed on how the framework may be used for any type of CI algorithm hybridisation with minimal development effort.

Dr. David Fogel visited CIRG from 31 August until 4 September, while he was in South Africa to be awarded an honorary doctorate by the University of Pretoria, for his contributions to the fields of computational intelligence and evolutionary computation. Dr. Fogel gave the opening address at the 3 September graduation ceremony for both the faculty of Natural and Agricultural Sciences, and the faculty of Engineering, Built Environment and Information Technology.
The following short biography is adapted from Dr. Fogel's page on the web site of his company, Natural Selection, Inc.:
Dr. Fogel's experience includes over 20 years of applying computational intelligence methods and statistical experimental design to real-world problems in industry, medicine, and defense. Prior to joining Natural Selection, Inc. in 1993, he was a Systems Analyst for Titan Systems, Inc. (1984-1988), and a Senior Principal Engineer at ORINCON Corporation (1988-1993). He received the Ph.D. in engineering sciences from the University of California at San Diego in 1992, and has subsequently taught undergraduate and graduate courses in evolutionary computation, stochastic processes, and statistical process control. Dr. Fogel has over 200 publications in the technical literature, the majority treating the science and application of evolutionary computation. He is also the author of six books.

Nelis Franken has developed a visualisation tool, called FluxViz, for the parameter optimisation of various CI algorithms. The approach is interactive, parameter-free and mathematically sound. It is also independent of the algorithm being optimised, or the code library being used, so anyone can use it successfully. FluxViz version 1.0 (stable) is now available for Linux, Windows and Mac OS on SourceForge.net, and includes program source and a Windows 32-bit binary release. [ Show ]
On 22 February, Nelis gave a presentation on parameter optimisation using FluxViz and Sobol sequences. The presentation slides are available for download in PDF format. [ Show ]
Nelis also gave a two-part talk on 7 and 14 March, covering experiment design and statistical analysis applied to computational intelligence. These slides are also available for download. [ Show ]
