PaCa-ViT: Learning Patch-to-Cluster Attention in Vision Transformers

2023 IEEE/CVF Conference on Computer Vision and Pattern Recognition (CVPR).

By: R. Grainger*, T. Paniagua*, . Song, N. Cuntoor, M. Lee & T. Wu*

TL;DR: The proposed PaCa module is used in designing efficient and interpretable ViT backbones and semantic segmentation head networks and is significantly more efficient than PVT models in MS-COCO and MIT-ADE20k due to the linear complexity. (via Semantic Scholar)
