The proceedings of the 14th Italian Workshop on Neural Nets WIRN VIETRI 2003 are collected in this volume. The workshop, held in Vietri sul Mare (SA) June 4-7, 2003 was jointly organized by the International Institute for Advanced Scienti?c Studies "Eduardo R. Caianiello" (IIASS) and the Societ' a Italiana Reti Neuroniche(SIREN). Thevolumecoversup-to-datetopicsonneuralnetsand- lated ?elds. It contains invited review papers and selected original contributions presented in either oral or poster sessions by both Italian and non-Italian - searchers. The contributions have been assembled, for reading convenience, into four sections: Models, Architectures and Algorithms, Image and Signal Proce- ing, and Applications, plus two special sessions. The latter gives a fresh persp- tive in the ?elds of "Bioinformatics and Statistics" and "Formats Knowledge: Words, Images, Narratives", sharing the technical languages of the involved d- ciplines. The editors would like to thank the invited speakers and all the c- tributors whose highly quali?ed papers contributed towards the success of the workshop. Finally, special thanks go to the referees for their accurate work.
