Child abuse images removed from AI image-generator training source, researchers say
Washington (AP): Artificial intelligence researchers have said they deleted more than 2,000 web links to suspected child sexual abuse imagery from a dataset used to train popular AI image-generator tools.
The LAION research dataset is a huge index of online images and captions that's been a source for leading AI image-makers such as Stable Diffusion and Midjourney.
But a report last year by the Stanford Internet Observatory found it contained links to sexually explicit images of children, contributing to the ease with which some AI tools have been able to produce photorealistic deepfakes that depict children.
That December report led LAION, which stands for the nonprofit Large-scale Artificial Intelligence Open Network, to immediately remove its dataset. Eight months later, LAION said in a blog post on Friday that it worked with the Stanford University watchdog group and anti-abuse organisations in Canada and the United Kingdom to fix the problem and release a cleaned-up dataset for future AI research.
Stanford researcher David Thiel, author of the December report, commended LAION for significant improvements but said the next step is to withdraw from distribution the “tainted models” that are still able to produce child abuse imagery.
One of the LAION-based tools that Stanford identified as the “most popular model for generating explicit imagery” - an older and lightly filtered version of Stable Diffusion - remained easily accessible until Thursday, when the New York-based company Runway ML removed it from the AI model repository Hugging Face. Runway said in a statement Friday it was a “planned deprecation of research models and code that have not been actively maintained”.
The cleaned-up version of the LAION dataset comes as governments around the world are taking a closer look at how some tech tools are being used to make or distribute illegal images of children.
San Francisco's city attorney earlier this month filed a lawsuit seeking to shut down a group of websites that enable the creation of AI-generated nudes of women and girls. The alleged distribution of child sexual abuse images on the messaging app Telegram is part of what led French authorities to bring charges on Wednesday against the platform's founder and CEO, Pavel Durov.
Durov's arrest “signals a really big change in the whole tech industry that the founders of these platforms can be held personally responsible,” said David Evan Harris, a researcher at the University of California, Berkeley who recently reached out to Runway asking about why the problematic AI image-generator was still publicly accessible. It was taken down days later.

Michael B Jordan wins best actor for ‘Sinners', taking home his first Oscar
Los Angeles (AP): Michael B Jordan has been building toward a performance like “Sinners” for over 20 years. Now he has the best actor Oscar as his reward.
Jordan got one trophy for playing identical twins Smoke and Stack in the blues-seeped supernatural horror film set in 1930s Mississippi that earned a record 16 Academy Award nominations.
Last year's winner, Adrien Brody, announced Jordan's name Sunday night, setting off a wild celebration inside the Dolby Theatre. Teyana Taylor, a supporting actress nominee, joined the standing ovation, mouthing, “Yes!”
“Whew, man,” Jordan said, clutching the trophy.
Jordan is the sixth Black man to win the best actor trophy. He joins Will Smith (“King Richard”, 2020), Forest Whitaker (“The Last King of Scotland”, 2006), Jamie Foxx (“Ray”, 2004), Denzel Washington (“Training Day”, 2001) and Sidney Poitier (“Lillies of the Field”), who was the first in 1963.
“I stand here because of the people that came before me — Sidney Poitier, Denzel Washington, Halle Berry, Jamie Foxx, Forest Whitaker, Will Smith,” he said, “and to be up amongst those giants, amongst those greats, amongst my ancestors, amongst my guys, thank you everybody in this room and everybody at home supporting me over my career.”
Jordan added, “I know you guys wanted me to do well and I want to do that because you guys bet on me, so thank you for keep betting on me. I'm going to keep stepping up, and I'm going to keep being the best version of myself I can be.”
The other nominees were Timothee Chalamet in “Marty Supreme”, Leonardo DiCaprio for “One Battle After Another”, Ethan Hawke of “Blue Moon” and Wagner Moura in “The Secret Agent”.
Chalamet had been the early Oscar favourite after wins at the Golden Globes and Critics Choice Awards. But Jordan surprised himself by winning at the Actor Awards, giving him momentum in the final days of Oscar voting.
“Sinners” reunited Jordan and writer-producer-director Ryan Coogler. They go back to their first collaboration in 2013.
“You're an amazing person,” Jordan told Coogler from the stage. “You gave me the opportunity and space to be seen.”
Jordan's breakthrough film role came in Coogler's “Fruitvale Station” for which he received critical praise playing a real-life man who was killed by police. It was Coogler's directorial debut, and they followed with “Creed”, “Black Panther” and now “Sinners”.
Jordan's initial acting success came in television. He had a small yet pivotal role in “The Wire” in 2002, followed by the daytime drama “All My Children”, in which he replaced Chadwick Boseman, and “Friday Night Lights”.
He and Boseman later acted together in “Black Panther” and were close friends until Boseman's death from colon cancer in 2020. Jordan dedicated his acting award from this year's NAACP Image Awards to Boseman.
Jordan, a 39-year-old who also produces and directs, was born in Santa Ana, California, and grew up in Newark, New Jersey.
In a pop-culture moment, he was named People magazine's “Sexiest Man Alive” in 2020.
