On the Role of Weight Sharing During Deep Option Learning

no code implementations31 Dec 2019 Matthew Riemer, Ignacio Cases, Clemens Rosenbaum, Miao Liu, Gerald Tesauro

In this work we note that while this key assumption of the policy gradient theorems of option-critic holds in the tabular case, it is always violated in practice for the deep function approximation setting.

Stress-Testing Neural Models of Natural Language Inference with Multiply-Quantified Sentences

no code implementations30 Oct 2018 Atticus Geiger, Ignacio Cases, Lauri Karttunen, Christopher Potts

Standard evaluations of deep learning models for semantics using naturalistic corpora are limited in what they can tell us about the fidelity of the learned representations, because the corpora rarely come with good measures of semantic complexity.

Learning to Learn without Forgetting by Maximizing Transfer and Minimizing Interference

2 code implementations ICLR 2019 Matthew Riemer, Ignacio Cases, Robert Ajemian, Miao Liu, Irina Rish, Yuhai Tu, Gerald Tesauro

In this work we propose a new conceptualization of the continual learning problem in terms of a temporally symmetric trade-off between transfer and interference that can be optimized by enforcing gradient alignment across examples.

On the Effective Use of Pretraining for Natural Language Inference

no code implementations5 Oct 2017 Ignacio Cases, Minh-Thang Luong, Christopher Potts

Neural networks have excelled at many NLP tasks, but there remain open questions about the performance of pretrained distributed word representations and their interaction with weight initialization and other hyperparameters.

Automatic Expansion of the MRC Psycholinguistic Database Imageability Ratings

no code implementations LREC 2014 Ting Liu, Kit Cho, G. Aaron Broadwell, Samira Shaikh, Tomek Strzalkowski, John Lien, Sarah Taylor, Laurie Feldman, Boris Yamrom, Nick Webb, Umit Boz, Ignacio Cases, Ching-Sheng Lin

Unfortunately, word imageability ratings were collected for only a limited number of words: 9, 240 words in English, 6, 233 in Spanish; and are unavailable at all in the other two languages studied: Russian and Farsi.
