The number of memorized data items is reduced if some fuzziness in the representation of the data is introduced. Memory-based techniques are extended to deal with non-point objects in feature spaces. The effectiveness of this approach is demonstrated in a number of examples. in: Engineering Applications of Neural Networks, London 17-19.06.1996
