Equiprobable mappings in weighted constraint grammars
Arto Anttila | Scott Borgeson | Giorgio Magri
Proceedings of the 16th Workshop on Computational Research in Phonetics, Phonology, and Morphology

We show that MaxEnt is so rich that it can distinguish between any two different mappings: there always exists a nonnegative weight vector which assigns them different MaxEnt probabilities. Stochastic HG instead does admit equiprobable mappings and we give a complete formal characterization of them.

Efficient Computation of Implicational Universals in Constraint-Based Phonology Through the Hyperplane Separation Theorem
Giorgio Magri
Proceedings of the Fifteenth Workshop on Computational Research in Phonetics, Phonology, and Morphology

This paper focuses on the most basic implicational universals in phonological theory, called T-orders after Anttila and Andrus (2006). It develops necessary and sufficient constraint characterizations of T-orders within Harmonic Grammar and Optimality Theory. These conditions rest on the rich convex geometry underlying these frameworks. They are phonologically intuitive and have significant algorithmic implications.

Implicational Universals in Stochastic Constraint-Based Phonology
Giorgio Magri
Proceedings of the 2018 Conference on Empirical Methods in Natural Language Processing

This paper focuses on the most basic implicational universals in phonological theory, called T-orders after Anttila and Andrus (2006). It shows that the T-orders predicted by stochastic (and partial order) Optimality Theory coincide with those predicted by categorical OT. Analogously, the T-orders predicted by stochastic Harmonic Grammar coincide with those predicted by categorical HG. In other words, these stochastic constraint-based frameworks do not tamper with the typological structure induced by the original categorical frameworks.
