Talk by Ryan Cotterell: Musings on Linguistic Complexity and Typology

Ryan Cotterell, PhD student in the Johns Hopkins Computer Science Department, will give a talk at DIKU on Musings on Linguistic Complexity and Typology.

Abstract

Linguistic typology studies the range of structures present in human language. The main goal of the field is to discover which sets of possible phenomena are universal, and which are merely frequent. For example, all languages have vowels, while most—but not all—languages have an [u] sound. In this paper we present the first probabilistic treatment of a basic question in phonological typology: What makes a natural vowel inventory? We introduce a series of deep stochastic point processes, and contrast them with previous computational, simulation-based approaches. We provide a comprehensive suite of experiments on over 200 distinct languages.
