Abstract

This paper is concerned with a subclass of finite state transducers, called strict prefix deterministic finite state transducers (SPDFST's for short), and studies a problem of identifying the subclass in the limit from positive data. After providing some properties of languages accepted by SPDFST's, we showthat the class of SPDFST's is polynomial time identifiable in the limit from positive data in the sense of Yokomori.
