91. Knowledge Engineering for Real-Time Intelligent Control
Published: 9/1/2002
Authors: John Evans, Elena R Messina, James S. Dr. Albus, Craig I Schlenoff
Abstract: The key to real-time intelligent control lies in the knowledge models that the system contains. Three main classes of knowledge are identified: parametric, geometric/iconic, and symbolic. Each of these classes provides unique perspectives and advan ...
