Joe Pater will present on "learning probabilities over derivations" at the next McCarthy-Pater grant group meeting, Friday, October 19, in the Partee room at 11. He'll be talking about the work on Harmonic Serialism in the paper below, and will also discuss the general approach, including about how it can be applied to other derivational approaches to OT, with a summary of some work on learning in stratal OT that Alex Nazarov and he did last semester.
