Finalizing Artificial Intelligence
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
Slide

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.
Slide
8
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 with
Expert 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
Fitness Value
Is it feasible?
ES
NN
How good is it?
Slide
10
Genetic Algorithms with
Expert Systems & Neural Nets
If infeasible, return an
extremely bad Fitness
GA
Fitness Value
ES
NN
If it is a feasible solution,
send to Neural Network
