****************************************************************** * European Symposium * * on Artificial Neural Networks * * * * Brussels (Belgium) - April 20-21-22, 1994 * * * * PROGRAM and REGISTRATION FORM * ****************************************************************** Foreword ******** The actual developments in the field of artificial neural networks mark a watershed in its relatively young history. Far from the blind passion for disparate applications some years ago, the tendency is now to an objective assessment of this emerging technology, with a better knowledge of the basic concepts, and more appropriate comparisons and links with classical methods of computing. Neural networks are not restricted to the use of back-propagation and multi-layer perceptrons. Self-organization, adaptive signal processing, vector quantization, classification, statistics, image and speech processing are some of the domains where neural networks techniques may be successfully used; but a beneficial use goes through an in-depth examination of both the theoretical basis of the neural techniques and standard methods commonly used in the specified domain. ESANN'94 is the second symposium covering these specified aspects of neural networks computing. After a successful edition in 1993, ESANN'94 will open new perspectives, by focusing on theoretical and mathematical aspects of neural networks, biologically-inspired models, statistical aspects, and relations between neural networks and both information and signal processing (classification, vector quantization, self-organization, approximation of functions, image and speech processing,...). The steering and program committees of ESANN'94 are pleased to invite you to participate to this symposium. More than a formal conference presenting the last developments in the field, ESANN'94 will be also a forum for open discussions, round tables and opportunities for future collaborations. We hope to have the pleasure to meet you in April, in the splendid town of Brussels, and that your stay in Belgium will be as scientifically beneficial as agreeable.
