Microsoft has improved its facial recognition system to make it much better at recognizing people who aren't white and aren't male. The company says that the changes it has made have reduced error rates for those with darker skin by up to 20 times and for women of all skin colors by nine times. As a result, the company says that accuracy differences between the various demographics are significantly reduced.
