Grammar Acquisition

Some of my early post-dissertation work explored computational models of first language acquisition, in particular the acquisition of syntax. The Amber model, which represented grammatical knowledge as production rules and relied on a discrimination mechanism for learning, matched a number of phenomena from the literature on child language.

My recent work in this area has been less psychologically oriented but continues to focus on general learning methods that could be used in domains other than language. The Grids system, which began as a rational reconstruction of Wolff's SNPR, uses a simplicity metric to guide search through a space of context-free grammars.
