Causally Evaluating the Learnability of Formal Language Tasks

Vésteinn Snæbjarnarson, Anej Svete, Josef Valvoda +3

Language models, as multi-task learners, acquire a wide range of abilities during training. A fundamental question is how much task-specific data is needed to learn a given task. A…

Training Neural Networks as Recognizers of Formal Languages

Alexandra Butoi, Ghazal Khalighinejad, Anej Svete +3

Characterizing the computational power of neural network architectures in terms of formal language theory remains a crucial line of research, as it describes lower and upper bounds…

The Foundations of Tokenization: Statistical and Computational Concerns

Juan Luis Gastaldi, John Terilla, Luca Malagutti +3

Tokenization - the practice of converting strings of characters from an alphabet into sequences of tokens over a vocabulary - is a critical step in the NLP pipeline. The use of tok…

Nondeterministic Stacks in Neural Networks

Brian DuSell

Human language is full of compositional syntactic structures, and although neural networks have contributed to groundbreaking improvements in computer systems that process language…

Algorithms for Weighted Pushdown Automata

Alexandra Butoi, Brian DuSell, Tim Vieira +2

Weighted pushdown automata (WPDAs) are at the core of many natural language processing tasks, like syntax-based statistical machine translation and transition-based dependency pars…

The Surprising Computational Power of Nondeterministic Stack RNNs

Brian DuSell, David Chiang

Traditional recurrent neural networks (RNNs) have a fixed, finite number of memory cells. In theory (assuming bounded range and precision), this limits their formal language recogn…

Learning Hierarchical Structures with Differentiable Nondeterministic Stacks

Brian DuSell, David Chiang

Learning hierarchical structures in sequential data -- from simple algorithmic patterns to natural language -- in a reliable, generalizable way remains a challenging problem for ne…

Learning Context-Free Languages with Nondeterministic Stack RNNs

Brian DuSell, David Chiang

We present a differentiable stack data structure that simultaneously and tractably encodes an exponential number of stack configurations, based on Lang's algorithm for simulating n…

Efficiency through Auto-Sizing: Notre Dame NLP's Submission to the WNGT 2019 Efficiency Task

Kenton Murray, Brian DuSell, David Chiang

This paper describes the Notre Dame Natural Language Processing Group's (NDNLP) submission to the WNGT 2019 shared task (Hayashi et al., 2019). We investigated the impact of auto-s…
