Facebook's image recognition can now tell what you're wearing

Facebook's search tool is about to get way more visual. Director of Applied Machine Learning Joaquin Candela published a blog post today (accompanying his presentation at the Machine Learning @Scale event in New York City) to share updates about Facebook's AI-based image-recognition tool. The improvements can hone in on photos to the "pixel level" and will let users search images based on their content -- whether or not they've been manually tagged. "Until recently, online search has always been a text-driven technology, even when searching through images," he writes. "Whether an image was discoverable was dependent on whether it was sufficiently tagged or had the right caption -- until now."
