MIT App Inventor is an Apache-licensed visual programming environment for building mobile phone apps. In this presentation, we will explore the MIT App Inventor web interface and build a simple image classifier app for Android devices. We will explore collecting training data, training a small machine learning model, and deploying that model as part of an App Inventor app. By the end of the talk, participants will be able to test or install their creation onto an Android device. We will also provide a brief overview of educational resources available to teachers.
