EfficientDet is an efficient object detection model that achieves a very high mAP at a fraction of the compute requirements of other object detection models. It is made with a similar philosophy to that of EfficientNet with some additional methods for better multi-scale feature fusion. This is a follow up video of 'MobileNetV2 and EfficientNet' where we explored EfficientNet’s scaling methodology and the MBConv blocks it is made of in detail.
