Why the US Government Banned Investments in Some Chinese AI Startups

stp2y0 CommentsAIai lab, algorithms, artificial intelligence, china, machine learning, regulation

The more certain short-term impact is that US investors who are still interested in Chinese AI startups will have to do a whole lot more due diligence. The Treasury Department is not setting up a new government committee like CFIUS that will review every transaction investors submit, and is instead asking them to do their own homework and report whether they believe a Chinese AI company would be covered.Under the new rules, even if a Chinese startup’s AI model is smaller than the 1025-flops size threshold, a US investor might still have the responsibility to notify the Treasury Department about…

Topic, who also represents The Intercept in a similar DMCA case against OpenAI, as well as the nonprofit newsroom the Center for Investigative Reporting in a copyright infringement case against both OpenAI and Microsoft, says he is “confident that these kinds of DMCA claims are permitted under the Constitution.”Not all experts agree. “These claims make no sense and should all be dismissed, so I am not surprised by this ruling,” says Matthew Sag, a professor of law and artificial intelligence at Emory University. He believes the publishers failed to prove that OpenAI broke the law in part because they did…

Mittelsteadt adds that Trump could punish companies in a variety of ways. He cites, for example, the way the Trump government canceled a major federal contract with Amazon Web Services, a decision likely influenced by the former president’s view of the Washington Post and its owner, Jeff Bezos.It would not be hard for policymakers to point to evidence of political bias in AI models, even if it cuts both ways.A 2023 study by researchers at the University of Washington, Carnegie Mellon University, and Xi’an Jiaotong University found a range of political leanings in different large language models. It also showed…

How a Trump Win Could Unleash Dangerous AI

The reporting requirements are essential for alerting the government to potentially dangerous new capabilities in increasingly powerful AI models, says a US government official who works on AI issues. The official, who requested anonymity to speak freely, points to OpenAI’s admission about its latest model’s “inconsistent refusal of requests to synthesize nerve agents.”The official says the reporting requirement isn’t overly burdensome. They argue that, unlike AI regulations in the European Union and China, Biden’s EO reflects “a very broad, light-touch approach that continues to foster innovation.”Nick Reese, who served as the Department of Homeland Security’s first director of emerging technology…

Algorithms Policed Welfare Systems For Years. Now They’re Under Fire for Bias

“People receiving a social allowance reserved for people with disabilities [the Allocation Adulte Handicapé or AAH] are directly targeted by a variable in the algorithm,” says Bastien Le Querrec, legal expert at La Quadrature du Net. “The risk score for people receiving AAH and who are working is increased.”Because it also scores single-parent families higher than two-parent families, the groups argue it indirectly discriminates against single mothers, who are statistically more likely to be sole-care givers. “In the criteria for the 2014 version of the algorithm, the score for beneficiaries who have been divorced for less than 18 months is…

Social Media Tells You Who You Are. What if It’s Totally Wrong?

stp2y0 CommentsRAG modelsalgorithms, meta, Pinterest, plaintext, social media

A few years ago I wrote about how, when planning my wedding, I’d signaled to the Pinterest app that I was interested in hairstyles and tablescapes, and I was suddenly flooded with suggestions for more of the same. Which was all well and fine until—whoops—I canceled the wedding and it seemed Pinterest pins would haunt me until the end of days. Pinterest wasn’t the only offender. All of social media wanted to recommend stuff that was no longer relevant, and the stench of this stale buffet of content lingered long after the non-event had ended.So in this new era of…

Write a function that takes a positive integer as a parameter and displays the sum of all prime numbers less or equal to it. // Define a function named addPrimeSum that takes a single parameter 'number' function addPrimeSum(number) { // Initialize a variable 'result' to store the sum of prime numbers, starting from 0 let result = 0; // Define an inner function named isPrime that takes a single parameter 'num' function isPrime(num) { // If 'num' is less than 2, it is not prime, so return nothing (undefined) if (num < 2) return; // Loop from 2 to half…

But Salakhutdinov says that having a wealth of information about how users go about common and important tasks like shopping might be a crucial ingredient for getting them to stay on track. “Data is going to be very important,” he says.Ship ItAmazon’s agents are, of course, likely to be more focused on helping customers find and buy whatever they need or want. A Rufus agent might notice when the next book in a series someone is reading becomes available and then automatically recommend it, add it to your cart, or even buy it for you, says Rajiv Mehta, a vice…
