On-Device Training with Core ML - Make Your Pancakes Healthy Again!

Backing up the model The model stays on the device, which is great. They will lose the new version of the model unless we take care of that by sending it somewhere and later downloading it. Adding a new version of the model If the model stays and retrains on a device, what if we want to change it for a new model, let's say an improved one (not personalized)? If we do that, the user will also lose all the personalized parts of the model and will need to start from scratch. Usually we support those earlier versions too.
