of object detectors, called EfficientDet, which consistently achieve much better efficiency than prior art across a wide spectrum of resource constraints. In particular, with single-model and single-scale, our EfficientDet-D7 achieves state-of-the-art 55.1APon COCO test-devwith 77M param-eters and 410B FLOPs1, being 4x – 9x smaller and using
