Artificial Intelligence (AI) powered by Google's DeepMind algorithm may be more accurate at spotting breast cancer than real life doctors. The findings, published in Nature.com on Wednesday, come after researchers from Imperial College London and Google Health "trained" a computer to spot abnormalities on X-ray images of nearly 29,000 women. Separate studies used imagery from U.K. and U.S. women and concluded that in both countries the computer reduced instances where a cancer was either incorrectly identified or incorrectly missed. In the United States, the improvement was more noticeable -- offering a reported reduction of 5.7% in false positives, where a mammogram is wrongly diagnosed as abnormal. There was also a reduction of 9.4% in false negatives, where a cancer is missed. "In an independent study of six radiologists, the AI system outperformed all of the human readers," claimed the report.
