| Challenge: | preserving knowledge of target distribution by fine-tuning all layers can be expensive and may increase data volume requirements. |
| Approach: | They propose an efficient metric based on the diagonal of the Fisher information matrix (FIM score) to select the candidate layers for selective fine-tuning. |
| Outcome: | The proposed metric can select layers leading to strong performance on GLUE and SuperGLUE tasks and across distinct language encoders. |
