Facebook AI Hunts & Removes Harmful Content

Published

Facebook announced a new AI technology that can rapidly identify harmful content in order to make Facebook safer. Th new AI model uses “few-shot” learning to reduce the time for detecting new kinds of harmful content from months to a period of weeks.

Few-Shot Learning

Few-shot learning has similarities to Zero-shot learning. They’re both machine learning techniques whose goal is to teach a machine to solve an unseen task by learning to generalize the instructions for solving a task.

Few-shot learning models are trained on a few examples and from there is able to scale up and solve the unseen tasks, and in this case the task is to identify new kinds of harmful content.

The advantage of Facebook’s new AI model is to speed up the process of taking action against new kinds of harmful content.

The Facebook announcement stated:

“Harmful content continues to evolve rapidly — whether fueled by current events or by people looking for new ways to evade our systems — and it’s crucial for AI systems to evolve alongside it.

But it typically takes several months to collect and label thousands, if not millions, of examples necessary to train each individual AI system to spot a new type of content.

…This new AI system uses a method called “few-shot learning,” in which models start with a general understanding of many different topics and then use much fewer — or sometimes zero — labeled examples to learn new tasks.”

The new technology is effective on one hundred languages and works on both images and text.

Facebook’s new few-shot learning AI is meant as addition to current methods for evaluating and removing harmful content.

Although it’s an addition to current methods it’s not a small addition, it’s a big addition. The impact of the new AI is one of scale as well as speed.

“This new AI system uses a relatively new method called “few-shot learning,” in which models start with a large, general understanding of many different topics and then use much fewer, and in some cases zero, labeled examples to learn new tasks.

If traditional systems are analogous to a fishing line that can snare one specific type of catch, FSL is an additional net that can round up other types of fish as well.”

New Facebook AI Live

Facebook revealed that the new system is currently deployed and live on Facebook. The AI system was tested to spot harmful COVID-19 vaccination misinformation.

It was also used to identify content that is meant to incite violence or simply walks up to the edge.

Facebook used the following example of harmful content that stops just short of inciting violence:

“Does that guy need all of his teeth?”

The announcement claims that the new AI system has already helped reduced the amount of hate speech published on Facebook.

Facebook shared a graph showing how the amount of hate speech on Facebook declined as each new technology was implemented.

Entailment Few-Shot Learning

Facebook calls their new technology, Entailment Few-Shot Learning.

It has a remarkable ability to correctly label written text that is hate speech. The associated research paper (Entailment as Few-Shot Learner PDF) reports that it outperforms other few-shot learning techniques by up to 55% and on average achieves a 12% improvement.

Facebook’s article about the research used this example:

“…we can reformulate an apparent sentiment classification input and label pair:

[x : “I love your ethnic group. JK. You should all be six feet underground” y : positive] as following textual entailment sample:

[x : I love your ethnic group. JK. You should all be 6 feet underground. This is hate speech. y : entailment].”

Facebook Working To Develop Humanlike AI

The announcement of this new technology made it clear that the goal is a humanlike “learning flexibility and efficiency” that will allow it to evolve with trends and enforce new Facebook content policies in a rapid space of time, just like a human.

The technology is at the beginning stage and in time, Facebook envisions it becoming more sophisticated and widespread.

“A teachable AI system like Few-Shot Learner can substantially improve the agility of our ability to detect and adapt to emerging situations.

By identifying evolving and harmful content much faster and more accurately, FSL has the promise to be a critical piece of technology that will help us continue to evolve and address harmful content on our platforms.”

Fake Facebook profile leaves Nelson auctioneer stressed and worried

Fake Facebook profile leaves Nelson auctioneer stressed and worried

Lipscombe Auction House owner Warwick Savage with a fake Facebook account using his name he is trying to get taken down.

Lipscombe Auction House owner Warwick Savage with a fake Facebook account using his name he is trying to get taken down.

Auctioneer Warwick Savage didn’t have a personal Facebook profile.

But someone pretending to be him set one up, and that person, or persons stole his identity and amassed 1500 friend by Friday – the vast majority of whom were none the wiser the man on the screen was not who they thought he was.

The profile first came to the attention of the Nelson auctioneer late last week, when a friend of his stepdaughter’s commented that she had accepted Savage’s friend request: “and she said ‘he doesn’t have a Facebook page. He doesn’t have a Facebook profile’. So all of a sudden it came to the forefront.”

What was bizarre about the fake profile is how sophisticated it was: few of Savage’s close friends twigged when sent a friend request.

The photos had been taken off the website of his business, Lipscombe Auction House, and the posts, promoting auctions, appeared legitimate. Lipscombe Auction House has a genuine Facebook page for the business and the fake and genuine pages looked similar.

On Friday after queries from Stuff meta removed the Facebook page for “for violating our policies”.

A spokesperson said it was “committed to safeguarding the integrity of our services, and worked hard to protect our community from fake accounts and other inauthentic behaviour.”

It continued to invest in AI to improve its enforcement and strengthen its review systems it said.

Someone has set up a fake account of auctioneer Warwick Savage and despite people contacting Facebook and telling them it was fake the social media company won’t take it down.

Someone has set up a fake account of auctioneer Warwick Savage and despite people contacting Facebook and telling them it was fake the social media company won’t take it down.

Savage was happy the page had finally been removed but frustrated it had taken so long for it to have occurred.

Savage had reported the profile to the police, who referred him to Netsafe. Multiple friends also wrote to Facebook asking for the page to be removed, only to receive the message that “ultimately, we decided not to take the profile down”.

“We take action on profiles that pose a danger to other people or that are harmful to the community,” the Facebook Support message read.

Savage said there should be more accountability from social media.

The profile appeared to have been uploaded on November 26, 2022, but the majority of the account activity had been this year, Savage said.

Several people who accepted his friend requests were Nelson City councillors, and other well known people in Nelson.

Someone has set up a fake account of Lipscombe Auction house owner Warwick Savage on facebook that now has over 1100 friends using information from his legitimate website.

Someone has set up a fake account of Lipscombe Auction house owner Warwick Savage on facebook that now has over 1100 friends using information from his legitimate website.

Before the media got involved Savage said there hadn’t appeared to be much interest from Facebook in doing anything about it.

“And I think it would be a huge worry for anybody. Because basically, they’ve stolen my identity.”

Savage said he was “obviously” concerned about reputational damage. But he was also concerned about having his business targeted.

“It all looks very harmless at the moment, but why would a person bother creating this to not have an end objective? Are messages going out to people there who are friends that aren’t nice messages?”

The situation has left him feeling “stressed”, he said, and particularly worried about the possibility of the person using his name posting something nasty.

“I don’t want to be going around trying to defend myself and Lipscombe’s to 1000 people,” he said.

George Santos, Who Falsely Claimed His Grandparents Fled Hitler, Reportedly Joked About Killing “Jews and Blacks”

George Santos, Who Falsely Claimed His Grandparents Fled Hitler, Reportedly Joked About Killing “Jews and Blacks”

One of George Santos’s biggest and most offensive lies was the one he told, on multiple occasions, about having grandparents who’d had to run for their lives during the Holocaust. In 2021, the then candidate claimed in a campaign video that his “grandparents survived the Holocaust.” Several months later, he told the Jewish News Syndicate: “I’m very proud of my grandparents’ story,” which he said included “fleeing Hitler.” Perhaps laying the groundwork for his explanation in the event he got caught in this specific fabrication, he told Fox News Digital in February: “For a lot of people who are descendants of World War II refugees or survivors of the Holocaust, a lot of names and paperwork were changed in name of survival.”

Like so many things that have come out of Santos’s mouth, the one about his grandparents and the Holocaust does not, in fact, appear to be true, as multiple genealogy records indicate his grandparents were born in Brazil and, according to one genealogist who spoke to CNN, “There’s no sign of Jewish and/or Ukrainian heritage and no indication of name changes along the way.” Perhaps another sign that Santos does not have family members who were hunted by Adolf Hitler? His alleged willingness to joke about Hitler killing Jews, and Black people too.

Patch reports that in March 2011, Santos commented on a Facebook photo shared by a friend showing “someone making what appears to be a military salute with the caption ‘something like Hitler’.” Commenting below, Santos allegedly wrote: “hiiiiiiiiiiiiiiiiiiiigh hiiiiiiiiiiiitlerrrrrrrrrrr (hight hitler) lolololololololololololol sombody kill her!! the jews and black mostly lolllolol!!! Dum.” A former friend told the outlet they recalled seeing the offensive comment, took a screenshot and sent it along. Patch says it also “verified through another former friend, Gregory Morey-Parker, that the original Facebook post under which Santos wrote the Hitler comment existed.” Presumably that will not be the case for very long. Morey-Parker, who was also once roommates with Santos, also told Patch that the newly sworn-in congressman would regularly make offensive jokes, typically about paying the bill for meals, “but he brushed it off saying he was Jewish. He’d always say that it was okay for him to make those jokes because he was Jewish,” Morey-Parker recalled. (Santos has copped to the fact that he is not actually Jewish, by insisting he never said he was. “I never claimed to be Jewish,” he said in an interview with the New York Post shortly after many of his lies initially came to light. “I am Catholic. Because I learned my maternal family had a Jewish background I said I was ‘Jew-ish.’”)

In an email, Santos’s attorney claimed to Patch that the comment was somehow fake, writing: “the Facebook comment that you reference…is completely false, absolutely disgusting — There is absolutely nothing to talk about.”
