Thisvolumereportstheproceedingsofthe16thItalianWorkshoponNeuralNets WIRN 2005 and the satellite International Workshop on Natural and Arti?cial Immune Systems NAIS 2005. The workshops, held in Vietri sul Mare (SA) from 8 to 11 June, were jointly organized by the International Institute for Advanced Scienti?c Studies “EduardoR. Caianiello”(IIASS) and the Societ` a Italiana Reti Neuroniche (SIREN). The new format of the SIREN annual meeting—WIRN plus satellite conference—stemsfromthe aimofsharingneuralnetworkmeth- ologieswith close researchcommunities. The goalthis year was to recognizeand exploit a commonality of subsymbolic methods used both in neural networks and immune system research to study complex systems with a distinguishing common feature. All these systems are indeed constituted by a mass of elem- taryorganisms/computationalunits generatingensemblefunctionalities, suchas optimization and learning, denoting traits of intelligent thought. Moreover, like neural networks, the area of natural and arti?cial immune systems is also dev- oping in response to needs for a mix of inter- and multidisciplinary expertise, spanning immunology, biology, mathematics, computer science, and medicine, among others, having rebounding of models and results from biological to c- putational realms and vice versa as a great strength point. Thevolumecontainsinvitedreviewpapersandselectedoriginalcontributions presented in oral or poster sessions by both Italian and foreign researchers. The contributions have been assembled, for reading convenience, into eight sections. The?rstsectionreportsthe lecturegivenby the winner ofthe PremioCaianiello award. Sections II to V contain wide-spectrum papers on neural networks, split in four parts; models, architectures and algorithms, signal processing, and p- tern recognition, respectively.
