EfficientNet-Light-head-RCNN for Human Detection

Google has recently released new efficient model architectures for edge devices, I thought it would be cool to see what the results of these models are as a backbone for FasterRCNNN. The EfficientNet-Light-head-RCNN has 31MAP on pedestrian detection and run at 12 FPS on my GTX 1060. Only EfficientNet B0 was tested.

Downloading the data
