Baidu's Silicon Valley research lab (Baidu Photo) Baidu plans to announce a sweeping expansion of its partnership with graphics chip maker Nvidia on Wednesday, bringing Nvidia's latest chips into Baidu's cloud services for artificial intelligence research and optimizing Baidu's deep learning system. The two companies have been working together on AI-related projects for a few years now, and the new agreement, scheduled to be announced during the Baidu Create 2017 AI developer conference, expands on much of that existing work. Baidu is the Google of China, with over 75 percent of that country's internet search market share and hundreds of millions of active users for other internet services it offers, including public cloud computing. It's also one of the world's leading researchers in artificial intelligence, a division that until recently was led by former Stanford professor and AI expert Andrew Ng.
