"In this exercise, we introduce the steps of deploying an ML module through [Azure IoT Edge](https://docs.microsoft.com/en-us/azure/iot-edge/how-iot-edge-works). The purpose is to deploy a trained image classification model to the edge device. When the image data is generated from a particular process pipeline and fed into the edge device, the deployed model is able to make predictions right on the edge device without accessing to the cloud. \n",
