Visualization of dynamic systems with performance maps: A rough computing approach
James J. Alpigini · International Journal of Intelligent Systems · 2002
A visualization technique titled the “performance map” is considered, which is derived from the Julia set common in the visualization of iterative chaos. Such maps are generated automatically and require a minimum of a priori knowledge of the system under evaluation. By the use of intuitively derived evaluation rules combined with color coding, they convey a wealth of information to the informed user about dynamic behaviors of a system that may be hidden from all but the expert analyst. The concept of rough sets is then presented and used to derive a new set of rules to affect map generation. This derivation serves to formalize rule generation and further serves to minimize the number of variables to test during the system evaluation. © 2002 John Wiley & Sons, Inc.
