Amazon Web Services likes to spice things up at its annual AWS re:Invent conference with unexpected hardware announcements, with past surprises such as a semi-truck for transporting data, a machine-learning camera, and a miniature self-driving race car. Now you can add a machine-learning-enabled musical keyboard to the list. Kicking off the event overnight in Las Vegas, the company introduced AWS DeepComposer, a 32-key, two-octave keyboard that the company holds up as an early example of "generative" artificial intelligence. "Generative AI is one of the biggest recent advancements in artificial intelligence technology because of its ability to create something new," Amazon explains on the AWS DeepComposer site. "It opens the door to an entire world of possibilities for human and computer creativity, with practical applications emerging across industries, from turning sketches into images for accelerated product development, to improving computer-aided design of complex objects."
