Latent Positional Information is in the Self-Attention Variance of Transformer Language Models Without Positional Embeddings (2023.acl-short)
Copied to clipboard
| Challenge: | Recent research has called into question the necessity of positional embeddings in transformer language models. |
| Approach: | They propose to discard positional embeddings in transformer language models to facilitate more efficient pretraining. |
| Outcome: | The proposed model encodes strong positional information through shrinkage of self-attention variance. |
