An intuitive characterization for the reference vectors of a Kohonen map
The weight updating formula of Kohonen's algorithm may be viewed as the derivative of an objective error function when the input data are generated by a discrete probability distribution. A simple appealing characterisation for the reference vectors layout at the end of the learning phase has been derived from this interpretation. This characterisation can be used for defining a convergence index for Kohonen's algorithm, and for proposing a batch version of it. A first set of experiments with the batch approach is discussed.
