- Derivational Analogy
- derivational trace
Four kinds of problem solving:
- Search through operators: Good when there is little knowledge
- Plan instantiation: When plans are appropriate
- General Plan use: abstract plan gets used
- Analogy: When plans are relevent but not exact. [p636]
Carbonell 1983: Tranformational Analogy [638]. Took existing plan and
modified it at the action level.
Derivational Analogy: Stores the goals and justifications at different
levels for the actions taken, to facilitate plan adaptation. I think
that's why the term "derivational" is used. Imagine quicksort
implemented in Pascal and LISP. Their similarity is at the general
specification, not in the actual code. The actual code really wouldn't
help.
The derivational trace is stored which contains decisions,
justifications, and failure-cause propogations, as well as problems,
steps, and the solution.[640]
Also described are ways to get rules out of the cases in memory [644]
Summary author's notes:
- Page numbers are from the reprint in Shavlik and Dietterich's
Readings in Machine Learning.
- This is distinguished from my work in that I only save the
solution, and not the derivation, and I generate states in the
solution, in addition to the actions taken.
