Rationalizing Text Matching: Learning Sparse Alignments via Optimal Transport (2020.acl-main)
Copied to clipboard
| Challenge: | Existing models that use only rationales to explain a prediction are limited by the complexity of deep neural networks. |
| Approach: | They extend selective rationalization to text matching by using optimal transport to find a minimal cost alignment between inputs. |
| Outcome: | The proposed model achieves very sparse rationale selections with high fidelity while preserving prediction accuracy compared to strong attention baseline models. |
