| Challenge: | Existing models focus on single tasks, limiting comparability of neuron importance . ranking strategies overlook how task-dependent information pathways shape write-in effects of feed-forward network (FFN) neurons. |
| Approach: | They propose a gradient-free framework for task-aware neuron attribution and steering in multi-task vision-language models. |
| Outcome: | The proposed framework outperforms existing methods in identifying task-critical neurons and improves model performance after steering. |
