Implementation for "Representative Graph Neural Network"


The RepGraph layer is around 17 times smaller in computation complexity and over 5 times faster than Non-local with a 256x128 input.

On the semantic segmentation task, we achieve 45.8% mean IoU on ADE20K val set, 53.9% mIoU on PASCAL-Context, and 81.5% mIoU on Cityscapes.

On the object detection/segmentation task, we achieve 39.6 AP^box (vs. 39.0 of NL) and 36.0 AP^mask (vs. 35.5 of NL).
