Researchers from Sun Yat-sen University and Microsoft Research Asia introduced Image Relative Position Encoding (iRPE), a set of 2D-specific methods that enhance Vision Transformers by modeling directional spatial relationships. iRPE consistently improved ImageNet classification by up to 1.5% top-1 accuracy and COCO object detection by up to 1.7% mAP with minimal computational overhead.
Key insights
- Directional relative position encoding methods are crucial for effectively modeling 2D image data's inherent spatial structure.
- Contextual interaction mode for RPE, where it interacts with input feature embeddings, consistently outperforms a static bias mode.
- Relative Position Encoding (RPE) can effectively replace Absolute Position Encoding (APE) in image classification but APE remains necessary for accurate object detection.
