Case Based Reasoning

• Cases are represented by a series of features
• The answer is found by comparing a new case to a case in the case base.
• Similarity is a key to solving the problem.
• The distance measure is a good way of finding similarity, but there are others.
• Exam Questions
• Apply a distance measurement to A (given several cases)
• What is the nearest case to A (given several cases)?
• Develop a small CBR system?
• What similarity metric is good for a certain problem? Why?
• How can I update my case base?
• How are CBR systems like/unlike rule based systems?
• What are CBR systems good for?
• How can you develop a CBR system?
• How do CBR systems take advantage of experts?
