Autoregressive Entity Generation for End-to-End Task-Oriented Dialog (2022.coling-1)
Copied to clipboard
| Challenge: | Task-oriented dialog systems require external knowledge base to generate a response . current systems require scanning the KB at each turn, which is inefficient when the kb scales up . |
| Approach: | They propose to generate entity autoregressively before leveraging it to guide response generation. |
| Outcome: | Experiments on MultiWOZ 2.1 single and CAMREST show that the proposed system generates more high-quality and entity-consistent responses in an end-to-end manner. |
Bi-Granularity Contrastive Learning for Post-Training in Few-Shot Scene (2021.findings-acl)
Copied to clipboard
| Challenge: | Existing approaches to fine-tune pre-trained models to downstream tasks are limited by labeled examples. |
| Approach: | They propose to apply post-training on unlabeled task data before fine-tuning by contrastive learning that considers either token-level or sequence-level similarity. |
| Outcome: | Empirical results show that contrastive masked language modeling surpasses other methods in few-shot settings without the need for data augmentation. |
