Case-Based Reasoners
• Six reasoners:– CHEF– JULIA– CASEY– HYPO– PROTOS– CLAVIER
• Other potential uses of CBR
CHEF (1986)
• Meal planner• Find recipe that solves most goals• Predict and resolve possible problems• Simulate (with casual-rules) and revise• Repair-strategies
CASEY (1988)
• Diagnose patients• Reconciliation with repair-rules• Extends the Heart Failure Program (HFP)• Same accuracy, better performance than HFP
JULIA (1988)
• Meal designer• CBR with requirement/constraint posting• Starts with general prototype
- Substitutions- Change structure (relax constraints)
• Dialogue with user
HYPO (1988)
• Law interpretation• Argue an issue based on earlier cases– Compare and contrast– Three-ply argumentation (Modus Ponens/Tollens)
• Generation of hypothetical cases
PROTOS (1989)
• Classification of hearing-disorders• Finds the most likely match given inputs• Links:– Reminding– Prototype– Difference– Censor
CLAVIER (1989)
• Autoclave layout generator• Improve autoclave-loading• No casual model for the domain• Still evolving
