Evaluating NLP Models via Contrast Sets
Explore a 19-minute video lecture on evaluating natural language processing (NLP) models using contrast sets. Learn about the limitations of current evaluation methods for supervised learning tasks in NLP and how models often exploit dataset-specific correlations rather than learning the intended task. Discover the concept of contrast sets - hand-crafted perturbations created by dataset authors to capture their original intent and provide a more meaningful evaluation of model performance. Examine the proposed annotation paradigm for creating contrast sets and its application to 10 diverse NLP datasets. Understand how contrast sets offer a local view of a model's decision boundary and can reveal significant drops in performance compared to standard test sets. Gain insights into improving NLP model evaluation and dataset construction to better assess true linguistic capabilities.
