Learning Non-Autoregressive Models from Search for Unsupervised Sentence Summarization (2022.acl-long)
Copied to clipboard
| Challenge: | Text summarization aims to generate a short summary for an input text. |
| Approach: | They propose a non-autoregressive unsupervised summarization approach which performs edit-based search towards a heuristicically defined score and generates a summary as pseudo-groundtruth. |
| Outcome: | The proposed approach achieves state-of-the-art performance for unsupervised summarization, while improving inference efficiency. |

| Challenge: | Autoregressive language model for multilingual speech editing and zero-shot text-to-speech synthesis is available in 11 languages. |
| Approach: | They introduce an autoregressive neural codec language model which unifies multilingual speech editing and zero-shot text-to-speech synthesis across 11 languages. |
| Outcome: | The model generates high-quality, natural-sounding speech, even with limited per-language data . it shows robust performance in diverse linguistic settings, even in limited per language data compared to other models . |
