| Challenge: | a novel linear characteristic exclusive to transformer decoders is revealed: embedding transformations between sequential layers exhibit almost perfect linearity. |
| Approach: | They propose a cosine-similarity-based regularization to reduce layer linearity in transformer decoders. |
| Outcome: | The proposed method improves performance metrics on Tiny Stories and SuperGLUE but also decreases the linearity of the models. |
