Summary:How is it possible for proprietary AI models to enter patient care, without extensive peer reviews for algorithmic transparency? That's a question we should be asking about Epic's Deterioration Index, which has been utilized for several use cases, including COVID-19 patient risk models.The conversation about machine learning development largely centers on how individual organizations proceed - and whether they use adequate data, methods, algorithms, transparency, and a process that guarantees models do not go into production until they are tested and vetted.At the other end of the spectrum are AI models developed by Google and Facebook that are completely opaque,...
