Python implementation of Minimal Generalization rule learner (Albright & Hayes 2002, 2003)

• Currently implemented only up through A&H (2002, section 3.2)
  • Minimal generalization of rules with shared change
  • Rule reliability and lower confidence limit

Modifications of strict MinGen not yet implemented

• 3.3 Improving confidence with phonology

  • Broaden rules by learning phonological rules to fix misapplication

• 3.4 Overcoming complementary distribution

  • Generalize further by forming cross-context rules (swap changes of rules with common focus, A -> B / C __ D and A -> B' / C' __ D')
  • Learn phonological rules to fix misapplication, as above

• 3.7 Impugnment as a solution to the distributional encroachment problem

  • Comparison of rules related by more-general-than relation
  • Upper confidence limit
