QKVA grid: Attention in Image Perspective and Stacked DETR. (arXiv:2207.04313v2 [cs.CV] UPDATED)

We present a new model named Stacked-DETR(SDETR), which inherits the main
ideas in canonical DETR. We improve DETR in two directions: simplifying the
cost of training and introducing the stacked architecture to enhance the
performance. To the former, we focus on the inside of the Attention block and
propose the QKVA grid, a new perspective to describe the process of attention.
By this, we can step further on how Attention works for image problems and the
effect of multi-head. These …
