Microsoft states that its artificial intelligence tool can diagnose medical conditions up to four times more accurately than human physicians. Mustafa Suleyman, the company's AI chief, told The Verge that the long-anticipated application of AI in healthcare has arrived. The company's claim is based on findings published Thursday in the journal Science. The study evaluated Microsoft's AI system against human doctors using scenarios derived from medical case reports and emergency department data. To conduct these tests, Microsoft compiled the cases into a proprietary benchmark. Suleyman described the development as a significant milestone for the technology's role in improving patient care.
