Title:Error-driven learning in OT and HG: a comparison
Authors: Giorgio Magri
Comment:to appear in Phonology
Abstract:The OT error-driven learner is known to admit guarantees of efficiency, stochastic tolerance and noise robustness which hold independently of any substantive assumptions on the constraints. This paper shows that the HG learner instead does not admit such constraint-independent guarantees. The HG theory of error-driven learning thus needs to be substantially restricted to specific constraint sets.
