Convergence of Error-driven Ranking Algorithms
According to the OT error-driven ranking model of language acquisition, the learner performs a sequence of slight re-rankings triggered by mistakes on the incoming stream of data, until it converges to a ranking that makes no more mistakes. This learning model is very popular in the OT acquisition literature, in particular because it predicts a sequence of rankings that models gradualness in ch...
متن کاملTools for the robust analysis of error-driven ranking algorithms and their implications for modelling the child's acquisition of phonotactics
Error-driven ranking algorithms (EDRAs) perform a sequence of slight re-rankings of the constraint set triggered by mistakes on the incoming stream of data. In general, the sequence of rankings entertained by the algorithm, and in particular the final ranking entertained at convergence, depend not only on the grammar the algorithm is trained on, but also on the specific way data are sampled fro...
متن کاملNaive Parameter Learning for Optimality Theory - The Hidden Structure Problem
There exist a number of provably correct learning algorithms for Optimality Theory and closely related theories. These include Constraint Demotion (CD; Tesar 1995, et seq.), a family of algorithms for classic OT. For Harmonic Grammar (Legendre, Miyata and Smolensky 1990; Smolensky and Legendre 2006) and related theories (e.g. maximum entropy), there is Stochastic Gradient Ascent (SGA; Soderstro...
متن کاملSome Correct Error-driven Versions of the Constraint Demotion Algorithm
This paper shows that Error-Driven Constraint Demotion (EDCD), an errordriven learning algorithm proposed by Tesar (1995) for Prince and Smolensky’s (1993) version of Optimality Theory, can fail to converge to a totally ranked hierarchy of constraints, unlike the earlier non-error-driven learning algorithms proposed by Tesar and Smolensky (1993). The cause of the problem is found in Tesar’s use...
متن کاملRemarks on Optimality Theory and Language Change
The present chapter frames Optimality-Theoretic approaches to phonological and morphosyntactic change in the context both of theoretical linguistics and of the questions asked in traditional historical linguistics. Previous traditional, standard generative and OT accounts are discussed, including principles of change invoked (e.g., Transparency Principle, Naturalness Condition, Neutral Ground H...
