Meta rolls out AI ad-targeting tech in an effort to reduce discrimination
 

Meta is acting on its vow to reduce ad discrimination through technology. The company is rolling out a Variance Reduction System (VRS) in the US that ensures the real audience for an ad more closely matches the eligible target audience — that is, it shouldn't skew unfairly toward certain cultural groups. Once enough people have seen an ad, a machine learning system compares the aggregate demographics of viewers with those the marketers intended to reach. It then tweaks the ad's auction value (that is, the likelihood you'll see the ad) to display it more or less often to certain groups.
