Enable Fast Sampling for Seq2Seq Text Diffusion (2024.findings-emnlp)
Copied to clipboard
| Challenge: | Existing text generation methods use autoregressive (AR) methods, which generate tokens one by one, but are time-consuming. |
| Approach: | They propose an efficient model FMSeq which utilizes flow matching to straighten the generation path, thereby enabling fast sampling for diffusion-based seq2seq text generation. |
| Outcome: | The proposed model generates comparable quality to the SOTA diffusion-based DiffuSeq in just 10 steps, achieving a 200-fold speedup. |

| Challenge: | Existing systems that use memory as an "all-or-nothing" approach to memory usage are often static and rely on experience-following tendencies. |
| Approach: | They propose a framework that allows users to dynamically regulate memory reliance by adding context into the model's prompt. |
| Outcome: | The proposed model outperforms prompting and memory masking strategies in multiple scenarios. |
