TimpaTeks:用扩散语言模型引导实现文本原地修改

TimpaTeks: Automatic In-place Text Sequence Modification via Diffusion Language Model Steering

AI 导读

TimpaTeks 将激活引导扩展到扩散语言模型,实现无需指令微调模型的文本原地修改,在 IMDB 影评情感和合成猫狗数据集的概念引导实验中验证可行。该方法在修改的同时降低句子困惑度并保留原句结构,且因原地去噪而非构造额外提示词条件输出序列,计算成本低于基于提示词的 DLM 引导。

Abstract:We extend activation steering to diffusion language models (DLMs) and study a novel problem that arose due to the inference mechanism of DLMs: Modifying a text in-place to manifest a different concept. We propose TimpaTeks, an automatic in-place text modification mechanism using DLMs. Experiments on IMDB movie reviews (sentiment) and a synthetic Cats and Dogs Dataset (arbitrary, more unconventional concept steering) show that TimpaTeks provides a feasible novel mechanism to steer diffusion language model outputs in-place. TimpaTeks enables in-place modification while simultaneously lowers sentence perplexity and retaining the original sentence structre without the need of instruction tuned models. TimpaTeks is also computationally cheaper than prompt-based DLM steering, as it performs denoising in-place rather than constructing an additional prompt-conditioned output sequence.
