“#Twitter<\/a> drops image-cropping algorithm after finding bias<\/strong>”<\/p>\n

\n Twitter has been reviewing its algorithms for possible bias and recently stopped using an automated system for image cropping.

Twitter said Wednesday it was scrapp<\/a>ing an automated image-cropping system after its review found bias in the algorithm controlling the function.<\/p>\n

The messaging platform said it found the algorithm delivered “unequal treatment based on demographic differences” with whites and males favored over Blacks and females, and “objectification” bias that focused on a woman’s chest or legs, described as “male gaze.”<\/p>\n

The news<\/a> comes a month after Twitter said it was launching an algorithmic fairness initiative as part of an effort to reduce bias on its platform introduced by automation.<\/p>\n

Twitter in 2018 introduced a so-called saliency algorithm to crop images, aiming to improve consistency in the size of photos in one’s timeline and to focus on their most important elements.<\/p>\n

Rumman Chowdhury, head of Twitter’s software engineering and a specialist in ethics and artificial intelligence, said the company determined after its review that it is preferable to leave the cropping decisions to users.<\/p>\n

“We considered the tradeoffs between the speed and consistency of automated cropping with the potential risks we saw in this research,” she said in a blog post.<\/p>\n

“One of our conclusions is that not everything on Twitter is a good candidate for an algorithm, and in this case, how to crop an image is a decision best made by people.”<\/p>\n

The announcement comes amid heightened concerns over advanced algorithms which can deliver biased results due to a lack of data on minorities or other factors.<\/p>\n

This week, Amazon said it was extending a ban on law enforcement’s use of its facial recognition technology<\/a> amid fears that its flaws could amplify racial bias.<\/p>\n

Twitter’s initiative calls for “taking responsibility for our algorithmic decisions” with the aim of “equity and fairness of outcomes,” according to the company.\n <\/p>\n\n
