Effective Unsupervised Constrained Text Generation based on Perturbed Masking (2022.findings-acl)
Copied to clipboard
| Challenge: | Existing methods for constrained text generation stochastically sample edit positions and actions, which cause unnecessary search steps. |
| Approach: | They propose to extend perturbed masking technique to search for most incongruent token to edit and introduce four multi-aspect scoring functions to select edit action to further reduce search difficulty. |
| Outcome: | The proposed method achieves state-of-the-art in two representative tasks . it does not require supervised data, so it could be applied to different generation tasks. |
