✦ Synopsis

The self-organizing map (SOM) method that was developed by Kohonen has been examined preliminarily by applying some problems of chemical analysis using AES data, leading to promising results: using a twodimensional SOM, the items that are described qualitatively by linguistic expressions can be explained more quantitatively by the position of the spectral data on the SOM, together with a grey level expression. The composition of an unknown sample also can be determined precisely by a SOM that has been constructed using spectra from samples of known composition.
