We show that a modification of the Hebb-rule works well for this problem in a neural network realization and study numerically its convergence properties. An illustration for a more "concrete" situation is provided.13 pages, 7 figures; LEARNING'98 Madrid; 2 notations, 1 typo correctedCondensed MatterAdaptation and Self-Organizing Systemstext
