How Much Does Attention Actually Attend? Questioning the Importance of Attention in Pretrained Transformers (2022.findings-emnlp)
Copied to clipboard
| Challenge: | Pretrained language models use the attention mechanism to contextualize input inputs . but, we find that it is not as important as thought for pretrained models . |
| Approach: | They propose a probing method that replaces input-dependent attention matrices with constant ones. |
| Outcome: | The proposed method improves performance of pretrained language models without input-dependent attention. |
