Today we’re announcing: We’ve built and deployed GrokNet , a universal computer vision system designed for shopping. It can identify fine-grained product attributes across billions of photos — in different categories, such as fashion, auto, and home decor. GrokNet is powering new Marketplace features for buyers and sellers today and we’re testing automatic product tagging on Facebook Pages to help make photos shoppable. We’re also introducing Rotating View, a state-of-the-art 3D-like photo capability that allows anyone with a camera on their phone to capture multi-dimensional panoramic views of their listings on Marketplace. And we’ve advanced research by creating a state of the art technique to predict occluded or layered objects in photos (like a shirt beneath a jacket). These advancements are part of the foundation we’re building to develop an entirely new way to shop on our platforms — making it easier for individuals and small businesses to showcase their products to billions of people, and for buyers to find exactly what they’re looking for.
