Hypergraph based Understanding for Document Semantic Entity Recognition (2024.acl-long)
Copied to clipboard
| Challenge: | Existing document understanding models focus on entity categories while ignoring the extraction of entity boundaries. |
| Approach: | They propose a hypergraph attention document semantic entity recognition framework which uses hypergraph focus to focus on entity boundaries and entity categories at the same time. |
| Outcome: | The proposed framework can improve the performance of existing models on FUNSD, CORD, XFUND and SROIE. |
On Transferability of Bias Mitigation Effects in Language Model Fine-Tuning (2021.naacl-main)
Copied to clipboard
| Challenge: | PTLMs can exhibit biases against protected groups in a host of modeling tasks . but, fine-tuned LMs may propagate bias to downstream classifiers . |
| Approach: | They propose to use upstream bias mitigation techniques to reduce bias on downstream tasks by fine-tuning an upstream model and applying it to a downstream model. |
| Outcome: | The proposed model reduces bias on hate speech detection, toxicity detection and coreference resolution tasks over bias factors. |
