Adaptive three-dimensional self-organizing map with a two-dimensional input layer

This paper introduces an adaptive growing three-dimensional self-organizing map with the special feature of a matrix input layer instead of a one-dimensional vector. First a short description of growing SOMs is given and the fundamental advantages are mentioned. Then an extension of the original SOM from two to three dimensions with a growing feature is presented. By means of a selected example the general behaviour of the algorithm is illustrated.
