Still going strong after more than a decade, the Los Angeles-based Machine Project is profiled in this encyclopedic book that explores unconventional ways of seeing and thinking about the world. New essays and images capture the quirky essence of Machine Project, where vacations for plants, concerts for dentists, and operas for dogs are a few of the typical offerings produced at the informal, non-profit, educational institution in Los Angeles. Designed in collaboration with Kimberly Varella, this book reflects on Machine Project's ongoing artistic practice, featuring an extensive selection of photographs of past projects and documentation of new performance projects at the Tang Museum by Haruko Tanaka, Krystal Krunch, Hana van der Kolk, Carmina Escobar, Kamau Patton, Dawn Kasper, Joshua Beckman, Asher Hartman, and Chris Kallmyer among others.

A hands-on, application-based introduction to machine learning and artificial intelligence (AI) that guides young readers through creating compelling AI-powered games and applications using the Scratch programming language. Machine learning (also known as ML) is one of the building blocks of AI, or artificial intelligence. AI is based on the idea that computers can learn on their own, with your help. Machine Learning for Kids will introduce you to machine learning, painlessly. With this book and its free, Scratch-based, award-winning companion website, you'll see how easy it is to add machine learning to your own projects. You don't even need to know how to code! As you work through the book you'll discover how machine learning systems can be taught to recognize text, images, numbers, and sounds, and how to train your models to improve their accuracy. You'll turn your models into fun computer games and apps, and see what happens when they get confused by bad data. You'll build 13 projects step-by-step from the ground up, including: • Rock, Paper, Scissors game that recognizes your hand shapes • An app that recommends movies based on other movies that you like • A computer character that reacts to insults and compliments • An interactive virtual assistant (like Siri or Alexa) that obeys commands • An AI version of Pac-Man, with a smart character that knows how to avoid ghosts NOTE: This book includes a Scratch tutorial for beginners, and step-by-step instructions for every project. Ages 12+
