INTERNATIONAL WORKSHOP ON ARTIFICIAL NEURAL NETWORK IWANN'93 FINAL PROGRAMME Sitges (Barcelona), Spain June 9 - 11, 1993 SPONSORED BY IFIP (Working Group in Neural Computer Systems, WG10.6) IEEE Neural Networks Council UK&RI communication chapter of IEEE Spanish Computer Society chapter of IEEE AEIA (IEEE Affiliate society) ORGANISED BY Universidad Politecnica de Catalunya Universidad Autonoma de Barcelona Universidad de Barcelona UNED (Madrid) IWANN'91 (International Workshop on Artificial Neural Networks) was held in Granada (Spain) in September 1991. People from over 10 countries attended the Workshop, and over 50 oral presentations were given. IWANN'93 is schedules for next June, 1993 in Sitges (Spain) with the following final program. WELCOME TO DELEGATES It is a pleasure to invite you to attend the second edition of INT ERNATIONAL WORKSHOP ON ARTIFICIAL NEURAL NETWORKS (IWANN'93) to be held in Sitges (Barcelona, Spain) from June 9 to June 11, 1993, following the fir st edition done in Granada (Spain) during September, 1991. IWANN's main objective is to offer a forum for achieving a global, informative and advanced prespective on Artificial Neural Networks. In addition to co nventional Neural Networks aspects, IWANN'93 will also be concerned with complement ary topics such as neural computation theory and methodology, local computation mode ls, organization and structures resembling biological systems. The actual Workshop will consist of 111 papers arranged into techn ical sessions addressing the topics of Learning, Models, Biological perspectives, Hardw are implementations, Self-Organizing networks and Organizational principles, Artificial vision, Control, Communications, Software, Signal processing and Applicat ions. A total of six Invited Conferences will open their respective sess ions to be held in Room A, and their objective is to focus the State-of-the-Art, and moti vate discussion and participation. The Workshop is organized in cooperation with the Spanish RIG of t he IEEE Neural Networks Society, and the IFIP WG 10.6, and, is sponsored by the s panish "Comisin Interministerial de Ciencia y Tecnologa" (CICYT), the catalan "C omissi Interdepartamental per a la Recerca i Tecnologia" (CIRIT), and the organi zing Universities. Welcome to the Workshop. We hope that IWANN'93 will be scientifica lly very rewarding and a good oportunity to get to know our country. Enjoy Sitges and Barcelona, one of the most dynamic towns in Europe, and meet people worki ng in different topics of Neural Networks field. The IWANN'93 Committees look forward to seeing you there.
