Abstract

Work on theoretical developments and applications of the random neural network (RNN) has now spanned two decades, and its applications include the modeling of cortico-thalamic oscillations, image and video compression, network routing algorithms, relaxation based optimisation, and the detection of tumors in the human brain. This research has attracted several thousand citations. The basic model can be viewed as a network of discrete counter-automata that interact with each other and with the outside world, operating in real time. Its remarkable properties include product form solutions for different variants of the model, the proof of its approximation ability for bounded and continuous real-valued functions, and an O(N^3) time complexity backpropagation learning algorithm for the recurrent network. This talk will outline some of these theoretical and practical results, and present some links to new research issues that include gene regulatory networks and very low power digital electronics.

Speaker Biography

Erol Gelenbe is the Dennis Gabor Chaired Professor at Imperial College. He received the MS and PhD degrees from Brooklyn Poly, and is a graduate of METU Ankara. In 2010 he was awarded the Brooklyn Poly Distinguished Alumnus Award and elected Honorary Member of the Hungarian Academy of Sciences. He is a Member of the French National Academy of Engineering (Academie des Technologies), of the Turkish Academy of Sciences, and of Academia Europaea.

A Fellow of IEEE, ACM and IEE, he won the ACM SIGMETRICS Award in 2008 for his work on computer and network performance modelling and analysis. He received the Italian honours of Commander of Merit, and of Grand Officer of the Order of the Star. France awarded him the honour of Officer of Merit. In

1996 he was the first computer scientist to receive the Grand Prix France Telecom of the French Academy of Sciences. He has received Honoris Causa doctorates from the University of Liège (Belgium), University of Roma II (Italy), and Bogazici University (Istanbul, Turkey). Erol's research is currently funded by UK EPSRC and EU FP7. He also works with industry, and serves as Editor-in-Chief of The Computer Journal (Oxford University Press and British Computer Society), and on the editorial board of the Proc. Royal Society A.
