    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
