Neural Networks vs Expert Systems Neural Nets is to Expert Systems. . l As Neural Networks vs Expert Systems Neural Nets is to Expert Systems. . l As Recognition is to Thought Process Some problems can use either one l How do the experts solve it? Logical step-by-step fashion? … Expert System l Recognizing the big picture? … Neural Network l l Is enough historical data present? Yes. … Neural Network l No. … Expert System l Slide 6

Neural Networks vs. Expert Systems Can we use both together? YES! l Output of Neural Networks vs. Expert Systems Can we use both together? YES! l Output of neural net used as a fact in expert system: l l Vehicle suspension system diagnostics. Neural net classifies the behavior pattern of the shock absorber (shock is worn, ok, etc. ) Expert system uses result to perform diagnosis of the whole system. Expert System output as input to neural network: l l l Different expert systems can perform interpretation of individual events (ex. terrorist activities) Interpretation can serve as input to neural network Network identifies likelihood of perpetrator or commonalities among events Slide 7

Genetic Algorithms vs Neural Networks: l Build models of the real world l Use Genetic Algorithms vs Neural Networks: l Build models of the real world l Use models to make predictions Genetic Algorithms: l Typically uses an existing model (Fitness Function) l Searches for a good (or optimal) solution to the model.
