Copied to clipboard
| Challenge: | Recent studies have shown that most abstractive summarization models are unfaithful and suffer from a wide range of hallucination. |
| Approach: | They propose a candidate summary generation and ranking technique to improve summary factuality without sacrificing quality. |
| Outcome: | The proposed method shows that the model trained using the proposed method improves on factuality and similarity-based metrics without conflicting with the model. |
