Microsoft plans to spend $40 million to support collaborative projects leveraging artificial intelligence for medical research and discoveries. The five-year program, called AI for Health, is the fifth program Microsoft has rolled out as part of its AI for Good initiative, the tech giant announced Wednesday. Microsoft's AI for Good is a $165 million program to provide researchers and nonprofits with technology tools to address pressing concerns such as global climate, humanitarian and accessibility issues. "Artificial intelligence has the potential to solve some of humanity's greatest challenges, like improving the health of communities around the world," said Brad Smith, president of Microsoft, said in a statement. Microsoft CEO Satya Nadella said in a statement that AI "represents one of technology's most important priorities, and healthcare is perhaps AI's most urgent application."
