The benefits of errors
T. Biró · 2007
We compare three recent proposals adding a topology to OT: McCarthy's Persistent OT, Smolensky's ICS and Bíró's SA-OT. To test their learnability, constraint rankings are learnt from SA-OT's output. The errors in the output, being more than mere noise, follow from the topology. Thus, the learner has to reconstructs her competence having access only to the teacher's performance.
