In this chapter, we built an app that can recognize whether or not a photo has a hot dog. We accomplished this by training a machine learning model for image classification using Azure Cognitive Services and the Custom Vision service.
We exported models for CoreML and TensorFlow and we learned how to use them in apps for both iOS and Android. In these apps, a user can take a photo or pick a photo from their photo library. This photo will be sent to the model to be classified, and we will get a result that tells us whether or not the photo is of a hot dog.
