Learning the Appropriate Representation Paradigm by Circular Processing Units Sandro Ridella, Stefano Rovetta, and Rodolfo Zunino DIBE - Department of Biophysical and Electronic Engineering University of Genoa - Italy Proceedings of the 1995 European Symposium on Artificial Neural Networks Brussels, Belgium, April 1995, pp. 297-302. (c) 1995 De Facto Abstract This paper presents a neural model that exhibits, in a single architecture, the properties of other different, widely used schemes. Such a model can be regarded as the result of generalization of different feedforward architectures. The way its properties are achieved is very inexpensive in terms of computational load. Moreover, although the behavior of the single unit is conceptually different from that of the well-known “multi-layer perceptron”, the network layout is almost identical, thus allowing one to port all the knowledge available about the classical model onto the new scheme at very low cost.
