On January 9, Meta unveiled a new approach for the fair distribution of adverts across its channels. Variance Reduction System (VRS), a machine learning technique, distributes advertisements to qualified target audiences.
In June 2022, Meta announced a partnership with the Department of Justice (DOJ) and stated that it will cooperate with the US Department of Housing and Urban Development to ensure that housing advertisements were distributed fairly. This relationship has now been updated, and Meta said that it will introduce VRS for housing ads in the US. Additionally, it will broaden the VRS’s application to cover US credit and employment adverts. The parent company of Facebook has stopped offering the Special Ads audience feature, which allowed marketers to reach a larger audience with ads for jobs, housing, and credit.
Bayesian Improved Surname Geocoding (BISG), a method for estimating and aggregating racial distribution based on the publically accessible US Census statistics, is the foundation of VRS. An advertisement is first presented to a sizable audience. The algorithm then calculates the demographic breakdown of everyone who has seen the advertisement as a whole and compares it to the demographic breakdown of the eligible target group that the marketer has chosen. VRS strives continuously to narrow the gap between these groups of viewers by utilising the underlying machine learning techniques.
Additionally, Meta stated that in order to ensure algorithmic fairness and privacy protection, it will incorporate civil rights and responsible AI concepts into the product development process. “The VRS expands upon our ongoing efforts to assist in preventing discrimination. For efforts that sell housing, employment, or credit ads, this means limiting specific targeting possibilities, according to the statement.
Notably, for the past few years, the targeted ads debate has centred on Meta. The Data Protection Commission (DPC) of Ireland fined Meta €390 million ($414 million) on January 5 for utilising private user data to tailor adverts on its Facebook and Instagram platforms. The General Data Protection Regulation of the European Union served as the context for the DPC’s conclusion on the four-year investigation into the Meta advertisement policy (GDPR).
