A student researcher has found that Twitter’s image-cropping algorithm prefers faces that are slim, young and light-skinned
A graduate student at Switzerland’s EFPL university has discovered a bias in Twitter’s image-cropping ‘saliency’ algorithm.
Bogdan Kulynyc proved that the algorithm preferred faces that are light-skinned, slim and young. Twitter’s saliency algorithm decides the most interesting part of an image to crop for preview.
The researcher tested how the software responded to AI-generated faces
Kulynyc found that by he could manipulate the algorithm to be prefer faces by “making the person’s skin lighter or warmer and smoother; and quite often changing the appearance to that of a younger, more slim, and more stereotypically feminine person”.
He achieved this by using an AI face generator to create artificial people with varying features. He was then able to run the images through the algorithm to see which faces the software preferred.
“We should not forget that algorithmic bias is only a part of a bigger picture. Addressing bias in general and in competitions like this should not end the conversation about the tech being harmful in other ways, or by design, or by fact of existing,” said Kulynyc.
“A lot of harmful tech is harmful not because of accidents, unintended mistakes, but rather by design”Bogdan Kulynyc
“This shows how algorithmic models amplify real-world biases and societal expectations of beauty”
Twitter’s director of software engineering and head of AI Ethics Rumman Chowdhury says the findings “showcased how applying beauty filters could game the algorithm’s internal scoring model.
“We create these filters because we think that’s what ‘beautiful’ is, and that ends up training our models and driving these unrealistic notions of what it means to be attractive.”
Twitter’s “algorithmic bug bounty”
The findings mark the conclusion of Twitter’s first “algorithmic bug bounty”. The event was part of an in-house competition at the DEF CON security conference in LA.
Twitter rewarded the student $3500 for his efforts.
Last year, Twitter came under fire for cropping out Black faces
This comes after and incident last year, where the tech giant found that the preview crop was more likely to hide Black faces.
Twitter’s director of software engineering Rumman Chowdhury said the findings illustrated that “how to crop an image is a decision best made by people”.
Ukraine suspects group linked to Belarus in cyberattack
Kyiv believes a hacker group linked to Belarusian intelligence carried out a cyberattack that hit Ukrainian government websites this week
The group used malware similar to that used by one tied to Russian intelligence, a senior Ukrainian security official said.
Kyiv believes a cyberattack that hit Ukrainian government websites this week was carried out by a hacker group linked to Belarusian intelligence, according to a senior Ukrainian security official.
The attack used malware similar to that used by a group tied to Russian intelligence, defacing government websites with threatening messages.
Serhiy Demedyuk, deputy secretary of the national security and defense council, told Reuters that Ukraine blamed Friday’s attack on a group known as UNC1151, adding that the attack was cover for more destructive actions behind the scenes.
The attack splashed websites with a warning to “be afraid and expect the worst” at a time when Russia has amassed troops near Ukraine’s borders, and Kyiv and Washington fear Moscow is planning a new military assault on Ukraine.
White House Press Secretary Jen Psaki:
“We have information that indicates Russia has already prepositioned a group of operatives to conduct a false flag operation in eastern Ukraine. The operatives are trained in urban warfare and is using explosives to carry out acts of sabotage against Russia’s own proxy forces. Our information also indicates that Russian influence actors are already starting to fabricate Ukrainian provocations in state and social media to justify a Russian intervention.”
Russia has dismissed such fears as “unfounded”.
Meanwhile, Canadian Foreign Minister Melanie Joly is set to travel to Ukraine’s capitol, Kyiv, next week to reaffirm support for Ukrainian sovereignty and to reinforce efforts to deter “aggressive actions” by Russia, according to Ottawa on Saturday.
Joly released a statement, saying in part (quote):
“The amassing of Russian troops and equipment in and around Ukraine jeopardizes security in the entire region. These aggressive actions must be deterred.”
Canada, with a sizeable and politically influential population of Ukrainian descent, has taken a hard line with Moscow since the annexation of Crimea in 2014 – imposing punitive measures on more than 440 individuals and entities.
Prime Minister Justin Trudeau’s office said that he spoke to Ukrainian President Volodymyr Zelenskiy on Tuesday and “emphasized that any military incursion into Ukraine would have serious consequences, including coordinated sanctions.’
