Token Dropping for Efficient BERT Pretraining (2022.acl-long)
Copied to clipboard
| Challenge: | Existing methods to accelerate pretraining of transformer-based models are computationally expensive and degrade performance on downstream tasks. |
| Approach: | They propose a "token dropping" method to accelerate the pretraining of transformer-based models by 25% . they leverage the already built-in masked language modeling loss to identify unimportant tokens with practically no computational overhead. |
| Outcome: | The proposed method reduces the pretraining cost of BERT models by 25% while achieving similar overall performance on downstream tasks. |
