Abstract
THE INTEGRATION OF ARTIFICIAL NEURAL NETWORKS (ANNS) AND KNOWLEDGE-BASED EXPERT SYSTEMS IS AN IDEAL STEP IN THE DEVELOPMENT OF INTELLIGENT SYSTEMS. IN GENERAL, THE TWO METHODS COMPLEMENT EACH OTHER SUCH THAT ANNS PROVIDE 'SOFT' CONSTRAINTS, WHILE EXPERT SYSTEMS ALLOW 'HARD' CONSTRAINTS. SPECIFICALLY, ANNS PERFORM NONLINEAR FUNCTIONS, PATTERN RECOGNITION CAPABILITIES, FAULT TOLERANCE AND PARALLEL PROCESSING; WHILE EXPERT SYSTEMS INVOLVE LANGUAGE PROCESSING, FORMAL LOGIC AND RULE INTERPRETATION. HERE, WE INTEND TO EXPLOIT THE COMPLEMENTARY STRENGTHS OF NEURAL NETWORKS AND KNOWLEDGE-BASED EXPERT SYSTEMS TO CREATE A HYBRID REMOTE SENSING SYSTEM THAT CAN OUTPERFORM EITHER METHOD ALONE. IN OUR STUDY, WE PROPOSE TO DEVELOP AN ADVANCED REMOTE SENSING SYSTEM, WITHIN A HYBRID NEURAL NETWORK/EXPERT SYSTEMENVIRONMENT, TO BE INCORPORATED IN THE GEOSTATIONARY EARTH OBSERVATORY. THE SYSTEM WILL TAKE ADVANTAGE OF BOTH ANNS AND EXPERT SYSTEMS TO HANDLE GLOBAL AND LOCAL EVENT ISOLATION AND IDENTIFICATION, MEASUREMENT VALIDATION, INSTRUMENTATION CONTROL AND INFORMATION STORAGE. THE HYBRIDREMOTE SENSING SYSTEM WILL BE IMPLEMENTED WITHIN THE HYBRID NUEX SHELL, PROVIDING A VISUAL OBJECT ORIENTED DEVELOPMENT ENVIRONMENT FOR REAL-TIME REMOTE SENSING APPLICATIONS.
