A dynamically routed Mixture-of-Encoders framework, SCOPE, enhances Vision-Language Model (VLM) performance and efficiency by selectively activating specialized visual perception experts for each image-text pair. It surpasses static multi-encoder baselines while achieving significant reductions in computational cost and memory usage.
Key insights
- Dynamic, intelligent selection of visual experts outperforms brute-force aggregation, leading to superior VLM performance and efficiency.
- Text-conditioned routing is crucial for tasks with diverse queries, enabling the model to focus on the most relevant visual features for a given question.
- The proposed dual regularization and auxiliary loss scheme is essential for preventing router collapse and ensuring both balanced expert usage and decisive instance-level choices.
