| Challenge: | Recent work has begun to address routing instability in VQA models by grouping similar concepts or routing based on examples. |
| Approach: | They propose a Concept-Guided Routing framework which incorporates semantics of the answer options to guide expert selection in the training phase. |
| Outcome: | The proposed framework delivers strong performance across multiple VQA tasks, demonstrating the effectiveness of the proposed framework. |
