Abstract
In a method for a self-organizing neural network for representing multidimensional, nonlinear imaging functions onto simpler imaging functions use divider-membranes are employed for achieving an error free representation of the imaging function via the learning sample, allowing for a high level of generalization. Kohonen cell borders coincide with a required imaging function. The neural network can independently determine a number of neurons necessary for an error-free solution of a problem. A readout of the neural network can occur through the calculation of the minimum of the squares of the distances.
