One day you and everyone else you have ever known will cease to be. It's an uncomfortable but inevitable truth. If you could know your expiry date, would you want to find out?
Artificial intelligence at a US healthcare center is able to predict a patient's chance of dying within a year more accurately than medical personnel. However, no one knows exactly how it is able to do it.
Pennsylvania-based healthcare provider Geisinger tasked a machine-learning algorithm with calculating heart patient survival rates by analyzing nearly two million echocardiogram (ECG) results from 400,000 patients.
It was trained on two models. One was fed raw historical ECG data while the other was given the data as well as the age and sex of each patient.
The AI then had to detect patterns to predict the chances of a patient dying within a year or suffering additional complications. It achieved a score of 0.85, where one is perfect. Traditional methods achieved between 0.6 and 0.8.
According to an article in the New Scientist magazine, AI identified patterns that three cardiologists who separately viewed the ECGs couldn't pick out. Researchers do not know how the algorithm is able to do this, but it may be extremely beneficial.
"AI can potentially teach us things that we've been maybe misinterpreting for decades," said Brandon Fornwalt of Geisinger.
