Abstract: The Self-Organizing Map is a computational method for the visualization and analysis of high-dimensional data. Self Organizing Maps have been applied to ASDEX Upgrade data to define an ordered mapping of an 8-dimensional plasma parameter space onto aregular, 2-dimensional grid. The map has been used to trackthe plasma trajectory during theexperiments andmonitorthedisruptionrisk. Inordertofacewithevernewoperationalconditions, aperiodicalupdatingoftheSelfOrganizing Map is proposed.
