Output Strictly Local Functions
Jane Chandlee, Rémi Eyraud, Jeffrey Heinz · 2015
This paper characterizes a subclass of subsequential string-to-string functions called Output Strictly Local (OSL) and presents a learning algorithm which provably learns any OSL function in polynomial time and data.This algorithm is more efficient than other existing ones capable of learning this class.The OSL class is motivated by the study of the nature of string-to-string transformations, a cornerstone of modern phonological grammars.
