Some AI Technologies • Expert Systems: Diagnose, respond & act like a human expert • Neural Networks: Use data to predict outputs or interpret inputs • Genetic Algorithms: Use data to find “optimal” solutions • Fuzzy Logic: Facilitate solutions to human vagueness problems • Robotics: Mimic physical human processes • Natural-Language Processing: Mimic human communication • Intelligent Tutorials: Facilitate human learning • Computer Vision: Mimic human sensory(visual) process • Virtual Reality: Mimic human reality inside a computer • Game Playing: Beat humans in games, e.g. chess
Cognitive vs Biological AI • Cognitive-based Artificial Intelligence • Top Down approach • Attempts to model psychological processes • Concentrates on what the brain gets done • Biological-based Artificial Intelligence • Bottom Up approach • Attempts to model biological processes • Concentrates on how the brain works

Neural Networks vs Expert Systems • Neural Nets is to Expert Systems.... • As Recognition is to Thought Process • Some problems can use either one • How do the experts solve it? • Logical step-by-step fashion? … Expert System • Recognizing the big picture? … Neural Network • Is enough historical data present? • Yes. … Neural Network • No. … Expert System
Neural Networks vs. Expert Systems • Can we use both together? YES! • Output of neural net used as a fact in expert system: • 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: • 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
Genetic Algorithms vs Neural Nets • Neural Networks: • Build models of the real world • Use models to make predictions • Genetic Algorithms: • Typically uses an existing model (Fitness Function) • Searches for a good (or optimal) solution to the model.
Difference between Prediction and Optimization • Prediction: What is the nutrition content of a McDonald’s Happy Meal? • Optimization: What is the most nutritious meal at McDonald’s? • Solving optimization problems typically requires solving many iterations of smaller prediction problems.
Genetic Algorithms withExpert Systems & Neural Nets • GA can use ES to test feasibility of a chromosome. • Constraints often easy to express in rules...... • GA can use trained NN as the Fitness Function. GA ES Is it feasible? NN How good is it? Fitness Value
Genetic Algorithms withExpert Systems & Neural Nets If infeasible, return an extremely bad Fitness GA ES NN If it is a feasible solution, send to Neural Network Fitness Value
