Why it matters:Roughly 32% of AI research focused on computer vision, which grew 121% in those five years.
That tracks with the fact that anecdotally "a lot of the topics open in robotics have proven really hard to fix," Arnold says. "At the same time, there has been very rapid progress in language tasks, for example.
But when CSET researchers narrowed their analysis to highly cited papers, the Chinese Academy of Sciences was still the leader. Google is second, followed by China's Tsinghua University, Stanford and then MIT."China is absolutely a world leader in AI research, and in many areas, likely the world leader," Arnold says, adding the country is active across a range of research areas, including increasingly fundamental research.
