  1. Case Studies of Case-Based Reasoners Jan Berge Ommedal 26.09.2011

  2. Case-Based Reasoners • Six reasoners: • CHEF • JULIA • CASEY • HYPO • PROTOS • CLAVIER • Other potential uses of CBR

  3. CHEF (1986) • Meal planner • Find recipe that solves most goals • Predict and resolve possible problems • Simulate (with casual-rules) and revise • Repair-strategies

  4. CASEY (1988) • Diagnose patients • Reconciliation with repair-rules • Extends the Heart Failure Program (HFP) • Same accuracy, better performance than HFP

  5. JULIA (1988) • Meal designer • CBR with requirement/constraint posting • Starts with general prototype • Substitutions • Change structure (relax constraints) • Dialogue with user

  6. HYPO (1988) • Law interpretation • Argue an issue based on earlier cases • Compare and contrast • Three-ply argumentation (Modus Ponens/Tollens) • Generation of hypothetical cases

  7. PROTOS (1989) • Classification of hearing-disorders • Finds the most likely match given inputs • Links: • Reminding • Prototype • Difference • Censor

  8. CLAVIER (1989) • Autoclave layout generator • Improve autoclave-loading • No casual model for the domain • Still evolving

  9. Other uses of CBR • Retrieval-Only Aiding and Advisory System • Browseable/Searchable facility, coach or collegue • Passive role • Example: Architect’s Assistant • Example: Mediator’s Assistant • Example: WWII Battle Planner
