Google's Teachable Machine 2.0 elucidates the basics of machine learning

Google two years ago launched Teachable Machine, a web experiment intended to elucidate machine learning concepts. It let any user with a webcam train an AI model to output specific media -- an image, sound, speech, or GIF -- corresponding with a hand gesture, object, or activity. Now Teachable Machine is expanding to incorporate inputs beyond those it initially supported, including audio. Additionally, it will allow folks to export their trained models to websites, apps, devices, and more. Google says it worked with people across industries with different needs -- like architect Steve Saling, who has amyotrophic lateral sclerosis (ALS) -- to test and shape the new Teachable Machine.
