Automated Learning and Prototyping for Athletics and Creative Activity with Machine Learning (ALPACA ML) is a听machine learning toolkit for creating custom models of gesture and other embodied actions. Using a smartphone, the platform can collect data from sensors via Bluetooth, and users can build machine learning models to provide real-time feedback on activities from physical therapy to improving one鈥檚 golf chip. Laboratory for Playful Computation (LPC) researchers are conducting research on how young people can learn machine learning and statistical modeling through using the toolkit to build models of athletic and artistic activities.
