Learning to Learn to be Right for the Right Reasons (2021.naacl-main)
Copied to clipboard
| Challenge: | Recent work shows that models trained on held-out data perform poorly on hard instances . previous methods have resorted to manual methods of encouraging models not to overfit to superficial cues . |
| Approach: | They propose to explicitly learn a model that does well on both easy and hard tests . they use Choice of Plausible Alternatives and Commonsense Explanation to evaluate the model . |
| Outcome: | The proposed model performs well on easy and hard tests with superficial cues but performs poorly on hard ones without superficial cuings. |
