We want a learning method such that:
- Given no domain theory it should be as good as purely
inductive methods.
- Given a perfect domain theory it should be as good as
analytical methods.
- Given imperfect domain theory and imperfect data it should
combine the two and do batter than both inductive and
analytical.
- Accommodate an unknown level of error in training
data.
- Accommodate an unknown level of error in domain theory.
