The SOM allows to project high dimensional feature vectors of a process on a low dimensional (2D) space, where the process state trajectory can be displayed for supervision and visualization. Regions in this space describe different process conditions. This paper suggests three novel methods to define regions in the visualization space associated to different process conditions using prior knowledge of the process given as: a) Labeled data sets, b) Process model, and c) Fuzzy rules
