Age, gender, and emotion prediction

This chapter is going to cover a complete iOS application using Core ML models to detect age, gender, and emotion from a photo taken using an iPhone camera or from a photo in a user's phone gallery.

Core ML enables developers to install and run pre-trained models on a device, and this has its own advantages. Since Core ML lives in the local device, it is not necessary to call a cloud service in order to get the prediction results. This improves the communication latency and also saves data bandwidth. The other crucial benefit of Core ML is privacy. You don't need to send your data to a third party in order to get the results picked for you. The main downside of having an offline model is that the model ...
