Study Notes

Expert Systems

Designed to mimic human expert problem-solving capabilities
Use a knowledge inference engine to provide solutions and explain problems

Types of Expert Systems

Neural Networks Expert Systems: learn from data by adjusting weights between neurons; used in speech recognition, image classification, and natural language processing
Rule-based Expert Systems: use a set of rules to reason about a problem and provide solutions or recommendations
Fuzzy Logic Expert Systems: use fuzzy logic to handle uncertainty and imprecision in data; used in product recommendation systems and image recognition
Knowledge-based Expert Systems: use a knowledge base containing facts and rules about a specific domain

Knowledge Acquisition

Involves five stages:
- Identification: identifies problem characteristics
- Conceptualization: finds concepts to represent the knowledge
- Formalization: designs the structure to organize the knowledge
- Implementation: formulates rules and frames to represent the knowledge
- Testing: validates the rules that organize the knowledge

Knowledge Representation

Non-binary relationships can be represented by "reification" (considering an abstract concept to be real)
ISA (is a) or AKO (a kind of) relation is used to link a class and its superclass, and sometimes to link an instance and its class

Expert System Applications

Classification: identify an object based on stated characteristics
Diagnosis Systems: infer malfunction or disease from observable data
Monitoring: compare data from a continually observed system to prescribe behavior
Design: configure a system according to specifications
Scheduling & Planning: develop or modify a plan of action
Generation of Options: generate alternative solutions to a problem
Interpretation: infer situation descriptions from sensor data
Prediction: infer likely consequences of given situations
Debugging: provide incremental solutions for complex problems
Repair: execute a plan to administer a prescribed remedy
Control: repair, and monitor system behaviors

Knowledge Validation & Verification

V&V techniques offer the only way to judge the success of a knowledge base development system
