Targeted Adversarial Training for Natural Language Understanding (2021.naacl-main)
Copied to clipboard
| Challenge: | Existing adversarial training approaches focus on making adversarials less expensive or regularizing rather than replacing the standard training objective. |
| Approach: | They propose an algorithm to introspect current mistakes and prioritize adversarial training steps to where the model errs the most. |
| Outcome: | The proposed algorithm improves adversarial training for natural language understanding by introspecting mistakes and prioritizing training steps to where the model errs the most. |
Doc2SoarGraph: Discrete Reasoning over Visually-Rich Table-Text Documents via Semantic-Oriented Hierarchical Graphs (2024.lrec-main)
Copied to clipboard
| Challenge: | Existing work on document visual question answering fails to capture the differences and correlations between elements of a document and associated questions. |
| Approach: | They propose a document-visual question-answering challenge that exploits element-level semantics and employs hierarchical Graph structures to capture differences and correlations between elements. |
| Outcome: | The proposed model surpasses the state-of-the-art method and large language model in terms of Exact Match (EM) metric, demonstrating exceptional effectiveness. |
