Does Putting a Linguist in the Loop Improve NLU Data Collection?
We take natural language inference as a test case and ask whether it is beneficial to put a linguist `in the loop' during data collection to dynamically identify and address gaps in the data by introducing novel constraints on the task.
Information-theoretic Probing Explains Reliance on Spurious Features
In this work, we test the hypothesis that the extent to which a feature influences a model's decisions can be predicted using a combination of two factors: The feature's "extractability" after pre-training (measured using information-theoretic probing techniques), and the "evidence" available during fine-tuning (defined as the feature's co-occurrence rate with the label).
COGS: A Compositional Generalization Challenge Based on Semantic Interpretation
Natural language is characterized by compositionality: the meaning of a complex expression is constructed from the meanings of its constituent parts.
Universal linguistic inductive biases via meta-learning
To facilitate computational modeling aimed at addressing this question, we introduce a framework for giving particular linguistic inductive biases to a neural network model; such a model can then be used to empirically explore the effects of those inductive biases.
