In this course, participants will learn the basic concepts of Artificial Intelligence and Machine Learning, and how to build machine learning algorithms with Scratch, a free visual programming language. The course begins with a discussion of Machine Learning concepts (such as neural networks, image classification, and natural language processing). Next, participants will delve into some hands-on activities to reinforce their understanding of these concepts. For example, individuals will be guided to build some machine learning algorithms (e.g. image classifiers), and will be tasked to work in small groups to design and implement projects of their choice.
