AWhat changed
Paired text with task/domain instructions, assembled the MEDI multitask instruction dataset and trained a shared encoder with contrastive objectives to alter embeddings according to use case.
Scientific scope
Paired text with task/domain instructions, assembled the MEDI multitask instruction dataset and trained a shared encoder with contrastive objectives to alter embeddings according to use case. Mean pooling excludes instruction tokens, though attention includes them. Backbone/data/contrastive components are inherited; instruction robustness is empirical and new tasks need not behave correctly without fine-tuning. Original330training tasks/70evaluation tasks are version-specific; no medical task outcome is added.
