A new research paper investigates the transferability of representations learned by vision-based surgical skill assessment models across different scoring rubrics. The study found that while models trained on the JIGSAWS dataset could achieve good performance on the LASANA dataset, the reverse transfer was unsuccessful, likely due to annotation inconsistencies. Control experiments indicated that task-specific heads, rather than the backbone, carried most of the skill prediction burden, suggesting that further work is needed to disentangle transferable skill features from domain-specific visual patterns.
