2022 arXiv   pre-print
In this work, we present Spatial Prior-enhanced Self-Attention (SP-SA), a novel variant of vanilla Self-Attention (SA) tailored for vision transformers.  ...  Our largest model SP-ViT-L achieves a record-breaking 86.3% Top-1 accuracy with a reduction in the number of parameters by almost 50% compared to previous state-of-the-art model (150M for SP-ViT-L vs 271M  ...  enhanced by a combination of learned 2D Spatial Priors (SPs), called Spatial Prior-enhanced Self-Attention (SP-SA).  ...
