An improved Voronoi-diagram based neural net for pattern classification

We propose a novel two-layer neural network to answer a point query in Rⁿ which is partitioned into polyhedral regions. Such a task solves amongst others nearest neighbor clustering. As in previous approaches to the problem, our design is based on the use of Voronoi diagrams. However, our approach results in substantial reduction of the the number of neurons, completely eliminating the middle layer at the price of requiring only one additional clock step. In addition, the design process is also simplified while retaining the main advantage of the approach, namely its ability to furnish precise values for the number of neurons and the connection weights requiring neither trial and error type iterations nor ad-hoc parameters
