Meta-Learning the Difference: Preparing Large Language Models for Efficient Adaptation (2022.tacl-1)
Copied to clipboard
| Challenge: | Large pretrained language models are often domain- or task-adapted via finetuning or prompting. |
| Approach: | They propose to use domain-adaptive pretraining to prepare large pretrained language models for domain- or task-adaptation by learning to learn the difference between general and adapted PLMs. |
| Outcome: | Experiments on few-shot dialogue completion, low-resource abstractive summarization, and multi-domain language modeling show improvements in adaptation time and performance over finetuning or preparation via domain-adaptive pretraining. |
