LATEST technologies in artificial intelligence, chip, virtual reality and smart communities were the highlights of the Shanghai International Popular Science Products Expo, which closes today.

A Shanghai-based startup has developed a chip system with an artificial intelligence feature that works in a high performance and energy efficiency manner. Developed by Shanghai Westwell, it can be used both in the home and by industrial sectors, such as ports requiring artificial intelligence to recognize product category.

During an on-site demo at the expo, Westwell's chip system recognized and classified 1,000 pictures within one second with an accuracy rate of almost 100 percent, compared with traditional methods with an accuracy rate of 86 percent.
