While the library is normally the quietest room in the school, her ear-piercing screams sounded more like a horror movie than study hall.

As she hacked and rasped, a message popped up on its web interface: …

AI Could Predict Death. But What If the Algorithm Is Biased?

This study comes months after a joint study between UC San Francisco, Stanford, and Google, which reported results of machine-learning-based data mining of electronic health records to assess the likelihood that a patient would die in hospital. One goal of both studies was to assess how this information might help clinicians decide which patients might most benefit from intervention. The FDA is also looking at how AI will be used in health care and posted a …
