- Foreword -

Since its resurgence in the early 80s, the field of artificial neural
networks is rapidly moving. There was first an important, and sometimes
exaggerated, interest for neural techniques which were used in any kind of
application where conventional methods failed. Then, in the late 80s,
people began to realize that neural networks are not the miraculous
solution to all problems.

The truth is certainly somewhere between these two extremes: there is no
doubt that neural networks are an important step towards new data analysis
and function approximation tools, but they have to be used in appropriate
situations, and a deep knowledge of their properties, both theoretical and
practical, is necessary.

The purpose of the ESANN series of conferences is to present the latest
results in the fundamental aspects of artificial neural networks. The
fourth European Symposium on Artificial Neural Networks will be organized
in Bruges, on 24-26 April 1996. It will cover most of the main
theoretical, mathematical and fundamental new developments of the field:
learning, models, approximation of functions, classification, control,
signal processing, biology, self-organization and many other topics will be
treated during the conference.

The program committee selected about 50% of the submitted papers; this
severe selection guarantees the high quality of the presentations. Besides
these presentations, three invited speakers (Bernd Fritzke, Nicolas
Franceschini and Juha Karhunen) will present the state-of-the-art and the
recent developments in some particular aspects of the topics covered by the

The steering and program committees of ESANN'96 are pleased to invite you
to participate to this symposium. More than a formal conference presenting
the last developments in the field, ESANN'96 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
Bruges, one of the most beautiful mediaeval cities in the world.

Bruges, Belgium

Bruges is unique in Europe : a living city of human proportions where you
can wander to your heart's content in virtually unspoiled surroundings.
Know as the Venice of the North because of its network of canals and its
narrow streets with their typical facades, this city takes you back to long
forgotten times ! Admire Bruges by boat or on foot to get a new
perspective of what most people agree is "Europe's best preserved mediaeval
city". Enjoy the Flemish cuisine at any level from exclusive restaurant to
cheaper - but good - bistro and their Flemish cuisine.

Bruges is situated at about 100 km. from Brussels, and can very easily be
reached by train from Brussels main stations.

Hotel accommodation

Special rates for participants to ESANN'96 have been arranged at the
NOVOTEL HOTEL (3 stars), and at the IBIS HOTEL.

The Novotel hotel is situated close from Bruges station, and near to the
center of the town. It includes a restaurant, a bar/brasserie, and a
swimming pool. The conference will be held in this hotel. There is a
public parking under the hotel.
