A key challenge in these settings is the prevalence of one-sided feedback, where only positive examples are observed during training--e.g., in multi-label tasks like tagging people in Facebook photos, we may observe only a few tagged individuals, without knowing who else appears in the image. To address learning under such partial feedback, we introduce a Probably Approximately Correct (PAC) framework in which hypotheses are set functions that map each input to a set of labels, extending beyond single-label predictions and generalizing classical binary, multi-class, and multi-label models. Our results reveal sharp statistical and algorithmic separations from standard settings: classical methods such as Empirical Risk Minimization provably fail, even for simple hypothesis classes. We develop new algorithms that learn from positive data alone, achieving optimal sample complexity in the realizable case, and establishing multiplicative--rather than additive--approximation guarantees in the agnostic case, where achieving additive regret is impossible.

GOP lawmakers, tech investors, and even OpenAI have tied the anti-data-center movement in the US to Chinese interference. Experts say it's much more complicated than that. Right-wing officials and data center investors are increasingly claiming that data center protests are being funded and influenced by the Chinese government. OpenAI added to the discourse on Wednesday when it released a report describing a cluster of accounts originating in China that, the company said, had been spreading anti-data-center messages on social media. Experts who spoke to WIRED, however, are skeptical of the funding claims.

They swear they haven't peeked at the closely guarded secret and that they'll keep the cryptographic competition going. On a blustery March day, the artist Jim Sanborn received visitors at his studio on an isolated island in the Chesapeake Bay. The visitors sat him down in front of a laptop, and he typed in a secret message. They compressed the message using a unique hash function, sent that to the cloud, and wiped the laptop clean. Sanborn hoped that this action would set him free.

SpaceX to list on US stock market at $1.77tn valuation in largest ever debut IPO for Elon Musk's company comes in what is predicted to be a banner year for public offerings of AI companies SpaceX will become publicly traded on Friday after nearly two and a half decades as a private company. Executives are slated to ring the bell on Wall Street with the rocket ship maker's historic stock market debut. If all goes to plan, the company's initial public offering (IPO) will mint a valuation of $1.77tn - earning it the designation of the world's largest ever IPO. Elon Musk, the founder and CEO of SpaceX, has a large stake in the company as majority shareholder, so if investors' enthusiasm validates the eye-popping valuation, he would take the title of the world's first-ever trillionaire. Musk is also the CEO of Tesla, which is valued at $1.2tn.

Pokemon Go became a worldwide hit after its launch - but players may not know that their game data trained AI that will potentially help military drones during war. Pokemon Go became a worldwide hit after its launch - but players may not know that their game data trained AI that will potentially help military drones during war. Fri 12 Jun 2026 03.06 EDTLast modified on Fri 12 Jun 2026 03.38 EDT An AI model trained on data collected from users of Pokémon Go will potentially help military drones find their location in war zones. Pokémon Go, a 2016 augmented reality mobile game, allowed players to find and catch Pokémon in the real world using the cameras on their mobile phones, and exploded in popularity. In 2018, the company reported having more than 800m downloads worldwide.

As awareness grows, more Japanese adults are receiving answers to struggles that went unrecognized for years. Social camouflaging can help neurodivergent people navigate social situations, but researchers say the effort often comes with significant emotional and mental strain. The first major crisis in Yosuke's life came when he stood in front of his students. Until then, the 24-year-old had navigated his life with few obstacles. He had done well in school, scored highly on IQ tests and graduated from university without any major issues. But after securing his dream job as a geography and history teacher at a girls' high school two years ago, cracks began to show. "I couldn't read the room," says Yosuke, who recalls struggling to organize course materials and wrap up classes on time.

Few things amaze me like people who can solve a Rubik's Cube. Sure, lots of things amaze me more -- mountains, elaborate water features, how my dog sits on the couch and watches like he's super into it -- but it's a very specific kind of amazement that's like, Man, that's wild; I could never do that... nor do I really care to. But I like that other people are super into it to the point that there's now a Guinness World Record cottage industry of people solving them under different circumstances, and we've got a new top dog when it comes to solving a bunch of them while skydiving. A Rubik's Cube, the ultimate test of dexterity and spinning colored blocks.

Elon Musk's SpaceX valued at nearly $1.8tn ahead of record share sale SpaceX has raised $75bn (£56bn) from financial firms ahead of it becoming a publicly traded company on Friday, in what is expected to be the highest-value stock listing in history. In a filing with the US Securities and Exchange Commission, the space exploration and artificial intelligence (AI) company said it had sold $75bn in shares priced at $135 each. The share price matches the estimate SpaceX gave last week, leaving the firm's expected initial stock market value to be nearly $1.8tn. At that value, chief executive Elon Musk - already the richest man in the world - is set to become the world's first trillionaire. Once shares start trading, their value could rise or fall depending on how many shares are made available for sale, and how strong the demand is for those shares.
