Overview of this book

Machine learning presents an entirely unique opportunity in software development. It allows smartphones to produce an enormous amount of useful data that can be mined, analyzed, and used to make predictions. This book will help you master machine learning for mobile devices with easy-to-follow, practical examples. You will begin with an introduction to machine learning on mobiles and grasp the fundamentals so you become well-acquainted with the subject. You will master supervised and unsupervised learning algorithms, and then learn how to build a machine learning model using mobile-based libraries such as Core ML, TensorFlow Lite, ML Kit, and Fritz on Android and iOS platforms. In doing so, you will also tackle some common and not-so-common machine learning problems with regard to Computer Vision and other real-world domains. By the end of this book, you will have explored machine learning in depth and implemented on-device machine learning with ease, thereby gaining a thorough understanding of how to run, create, and build real-time machine-learning applications on your mobile devices.

Creating a text recognition app using Firebase on-cloud APIs

In this section, we are going to convert the on-device app to a cloud app. The difference is that on-device apps download the model and store it on the device. This allows for a lower inference time, allowing the app to make quick predictions.

By contrast, cloud-based apps upload the image to the Google server, meaning inference will happen there. It won't work if you are not connected to the internet.

In this case, why use a cloud-based model? Because on-device, the model has limited space and processing hardware, whereas Google's servers are scalable. The Google on-cloud text recognizer model is also able to decode multiple languages.

To get started, you need a Google Cloud subscription. Follow these steps:
