Model Overview

The final version of mlmodel originates from the latest techniques from WWDC 2021 (https://developer.apple.com/videos/play/wwdc2021/10039/). Previous version includes using CreateML Image Classifier model, and an transformed mlmodel from Pytorch model (using coremltools) , which gave disappointing performance on real-time debugging.

A diagram of the model structure can be seen in Snapshots.
