YouTube unveils the latest redesign with a focus on recommendations

YouTube promises to be dramatically smarter and easier to navigate with the latest mobile app update. The Android and iOS versions of the app feature larger images and a simplified interface make the video preview pop out more. The bigger change is behind the scenes, in the recommendation engine. Google says it's tapping into deep neural networks, which enables computers to learn from the information they gather over time. In practice you may see video suggestions that better match what you may want to see based on your viewing history.
