CaPE: Contrastive Parameter Ensembling for Reducing Hallucination in Abstractive Summarization (2023.findings-acl)
Copied to clipboard
| Challenge: | Existing work suggests that the degree of hallucination depends on factual errors in training data. |
| Approach: | They propose a method to use training data to reduce hallucination by ensembling parameter variations in training data. |
| Outcome: | The proposed method improves on XSUM and CNN/DM datasets on human evaluations and factual metrics. |
