Machine Learning (ML) has become a critical topic in any application's development. In a nutshell, ML means that you import data that "trains" an algorithm, and use it to generate a model. This trained model can then be used to solve problems that would be virtually impossible with traditional programming. To make this process more manageable, Firebase offers a service called ML Kit, an ML kit that we could define as "pre-built ML." Among other functionalities, it contains text recognition, image labeling, face detection, and bar-code scanning. For functionalities that are not already provided by ML Kit, you can create your own custom model with TensorFlow Lite. Most of the services outlined in this chapter can run both on the cloud or on your device.
