Researchers have identified a distinction between 'active' and 'inert' facts within language models, where active facts facilitate generalization beyond simple recall. This distinction was studied by creating new relations from existing ones, such as mapping places to continents and then relabeling those continents. The study found that the linear readability of the original relation in a model's pretrained representations strongly predicts its ability to generalize after fine-tuning on these new, relabeled facts. This generalization capability is more dependent on the linear structure of the facts than on their mere recall. AI
IMPACT This research could lead to more efficient fine-tuning by focusing on 'active' facts that promote generalization.
