The Stable Entropy Hypothesis and Entropy-Aware Decoding: An Analysis and Algorithm for Robust Natural Language Generation

no code implementations14 Feb 2023 Kushal Arora, Timothy J. O'Donnell, Doina Precup, Jason Weston, Jackie C. K. Cheung

State-of-the-art language generation models can degenerate when applied to open-ended generation problems such as text completion, story generation, or dialog modeling.

Story Generation

Evaluating Distributional Distortion in Neural Language Modeling

no code implementations ICLR 2022 Benjamin LeBrun, Alessandro Sordoni, Timothy J. O'Donnell

To address this gap, we develop a controlled evaluation scheme which uses generative models trained on natural data as artificial languages from which we can exactly compute sequence probabilities.

Systematic Generalization with Edge Transformers

1 code implementation NeurIPS 2021 Leon Bergen, Timothy J. O'Donnell, Dzmitry Bahdanau

Recent research suggests that systematic generalization in natural language understanding remains a challenge for state-of-the-art neural models such as Transformers and Graph Neural Networks.

Compositional Generalization in Dependency Parsing

no code implementations ACL 2022 Emily Goodwin, Siva Reddy, Timothy J. O'Donnell, Dzmitry Bahdanau

To test compositional generalization in semantic parsing, Keysers et al. (2020) introduced Compositional Freebase Queries (CFQ).

Linguistic Dependencies and Statistical Dependence

1 code implementation EMNLP 2021 Jacob Louis Hoover, Alessandro Sordoni, Wenyu Du, Timothy J. O'Donnell

Are pairs of words that tend to occur together also likely to stand in a linguistic dependency?

Characterizing Idioms: Conventionality and Contingency

no code implementations ACL 2022 Michaela Socolof, Jackie Chi Kit Cheung, Michael Wagner, Timothy J. O'Donnell

Second, the non-canonical meanings of words in an idiom are contingent on the presence of other words in the idiom.

Jointly Learning Truth-Conditional Denotations and Groundings using Parallel Attention

no code implementations14 Apr 2021 Leon Bergen, Dzmitry Bahdanau, Timothy J. O'Donnell

We present a model that jointly learns the denotations of words together with their groundings using a truth-conditional semantics.

Probing Linguistic Systematicity

1 code implementation ACL 2020 Emily Goodwin, Koustuv Sinha, Timothy J. O'Donnell

Recently, there has been much interest in the question of whether deep natural language understanding models exhibit systematicity; generalizing such that units like words make consistent contributions to the meaning of the sentences in which they appear.

CLOSURE: Assessing Systematic Generalization of CLEVR Models

3 code implementations12 Dec 2019 Dzmitry Bahdanau, Harm de Vries, Timothy J. O'Donnell, Shikhar Murty, Philippe Beaudoin, Yoshua Bengio, Aaron Courville

In this work, we study how systematic the generalization of such models is, that is to which extent they are capable of handling novel combinations of known linguistic constructs.

no code implementations31 Oct 2017 Daniel Harasim, Chris Bruno, Eva Portelance, Martin Rohrmeier, Timothy J. O'Donnell

This technical report presents a general framework for parsing a variety of grammar formalisms.
