用扩散模型实现从粗到细的可控文本编辑，支持粗调与微调。
EdiText: Controllable Coarse-to-Fine Text Editing with Diffusion Language Models
- 结合SDEdit与自条件机制，实现多尺度文本编辑。
- 在毒性与情感控制任务中展现强鲁棒性，支持灵活调整程度。
- 适合需要精确文本修改的研究者与应用开发人员。
我们提出EdiText，一种可控制的文本编辑方法，能在不同尺度上将参考文本修改为目标属性。该方法整合了基于SDEdit的编辑技术，支持大范围的文本调整。此外，我们提出一种基于自条件的新颖细粒度编辑方法，可对参考文本进行细微控制。该细粒度方法独立运作，亦可与SDEdit结合使用，使EdiText能够在指定范围内实现精准调整。EdiText在多种任务中展现出良好的可控性，包括毒性控制和情感控制，能稳健地在广泛水平上调整参考文本。
原文摘要 · Abstract (English)
We propose EdiText, a controllable text editing method that modifies the reference text to desired attributes at various scales. We integrate an SDEdit-based editing technique that allows for broad adjustments in the degree of text editing. Additionally, we introduce a novel fine-level editing method based on self-conditioning, which allows subtle control of reference text. While being capable of editing on its own, this fine-grained method, integrated with the SDEdit approach, enables EdiText to make precise adjustments within the desired range. EdiText demonstrates its controllability to robustly adjust reference text at a broad range of levels across various tasks, including toxicity control and sentiment control.
