Abstract
In previous works [1,2,3], the behavior of a fully-connected single-layer Random Neural Network (RN) [4,5] has been illustrated in a problem of pattern completion. We applied the gradient-descent learning algorithm which has been introduced by Gelenbe [6,7] for recurrent RN networks. The recall of any training pattern from a corrupted version consists in a progressive retrieval process with adaptive threshold. We have reduced the influence of the pattern geometry on the performance by modifying the computation of the network state. The experimental results are now compared to thoses obtained with Hopfield's network. As the learning times in such a model become rapidly prohibitive, we look into the use of a single-layer network with local interactions between neurons. The connectivity influence on the convergence of the learning algorithm and on the recognition rates is particularly examined.
