Image: Google, via Nature Google, in its bid to move into healthcare, reports that researchers have successfully trained AI to detect breast cancer with greater accuracy than doctors. In a Google-funded study , a team of independent researchers from various hospitals and universities, researchers from Google Health, and engineers from DeepMind (a Google-owned UK-based AI company) compared analyses of nearly 29,000 mammograms from UK and U.S.-sourced datasets. The study reports that they found 9.7% and 2.7% reductions in false negatives in the U.S. and UK, respectively, and false positives reduced by 5.7% and 1.2%, respectively. This was despite the fact that the AI had less information to work with. In its control study, Google gave six radiologists 500 randomly-selected mammograms from its U.S. dataset, along with access to patients’ age, breast cancer history, and previous mammograms. Google provides limited information on the demographics of its survey sample, but if […]
