T. Kohonen
     
         A researcher at the {University of Helsinki} who has
        been studying {neural networks} for many years with the idea
        of modelling as closely as possible the behaviour of
        biological systems.  His name is commonly associated with a
        particular kind of neural network in which there are only two
        kinds of {neurons} (see {McCulloch-Pitts}), input and others.
        All the input neurons are connected to all others and the
        others are connected only to their other nearest neighbors.
        The training {algorithm} is a relatively simple one based on
        the geometric layout of the neurons, and makes use of
        {simulated annealing}.
