Alexa-maker Amazon is creating a machine learning and artificial intelligence research lab at USC as the retail giant grapples with growing privacy concerns around its products. The Center for Secure and Trusted Machine Learning, part of USC's Viterbi School of Engineering, will support research that looks at new ways to secure and preserve privacy in machine learning and can be applied at scale "to support billions of users."

Amazon's artificial intelligence systems extend beyond its smart home devices; the company automates much of its processes using machine learning; including product recommendation, the Amazon Echo and the Amazon Go store (a brick and mortar location that runs without cashiers). Amazon also recently launched Halo, a wearable fitness tracker comparable to the Fitbit that also connects with Alexa and the rest of its smart devices.
