Challenge: Existing work assesses models’ generalization capabilities through the lens of performance on out-of-distribution (OOD) datasets.
Approach: They challenge this assumption by comparing OOD evaluations with failure modes documented in existing question-answering (QA) models.
Outcome: The proposed evaluations show that the models' generalization capabilities are under-performing on out-of-distribution datasets, while others are underperforming on in-difference datasets.
