(Original title:) How long do you have left to live? A new AI could have the answer)
According to a report by Wired Magazine, researchers at the University of Adelaide conducted an unprecedented study using artificial intelligence to predict human life. The accuracy is comparable to that of doctors.
Artificial intelligence predicts which patients will die in the next five years by analyzing the chest image of the patient with an accuracy of 69%, which is comparable to the accuracy of human doctors' judgment.
Although predicting death sounds unpleasant, research results may have a significant impact on the early diagnosis of serious illness and help doctors personalize the treatment of patients.
“Because doctors cannot measure the health of every organ in a patient, the accurate assessment of biological age has been limited,†said Dr. Luke Oakden-Rayner of the Adelaide School of Public Health.
Researchers use "deep learning" techniques to allow computer systems to learn to understand and analyze perspective images. Although the researchers could not determine what the computer saw on the chest radiograph, the accuracy of computer predictions for patients with severe chronic diseases such as emphysema and congestive heart failure was high.
Dr. Oakden-Rayner said that automated systems are focused on predicting medical outcomes rather than diagnosing diseases, opening up new avenues for the use of artificial intelligence technology in medical image analysis.
Although the subject of the study is interesting, the sample of 48 patients is relatively small. The research team plans to expand the number of samples to tens of thousands in the next phase of research, and also envision new usage scenarios, such as letting AI predict the onset of heart attacks.
"Although only a small sample of patients was used in this study, our research shows that computers have learned to recognize complex disease image presentations. The same work human experts need comprehensive training to do so," said Dr. Oakden-Rayner.
This is not the first time AI has been used to predict events related to life and death.
Last year, researchers at the Methodist Institute in Houston, Texas, developed an artificial intelligence software that can accurately predict breast cancer risk.
The AI ​​program accurately analyzes mammograms and quickly gives diagnostic information. The diagnostic speed is 30 times faster than the human doctor and the accuracy is as high as 99%. (Sun Wenwen)
