This year's ImageNet, and possibly the last competition, ended with Chinese AI teams' sweeping victory, yet again. All the top performers were from China, and more than half of the 27 competing teams were Chinese-based universities or institutes. On the image classification challenge, the prize went to a team called WMW, which included two experts from Beijing-based startup Momenta and another one from Oxford University. Their error rate was 2.25 percent. Another team called DBAT won the title in the object detection challenge, with an accuracy rate at 73.1 percent.

A photo shows the logo of Renren.com. Will robots take over our world? These questions, which once seemed irrelevant, now frequently come into our minds with the advancement of Artificial Intelligence (AI). A recent report shows that there are almost no active users left on Renren, as advertising accounts keep pushing uninteresting contents and the system keeps recommending other people's posts that were so "yesterday". Some have jokingly said this must be what will happen to our world after it is taken by AI.
