What are Russia's gains from the Iran war? 'We are not losers; we are winners' Russia's Ministry of Foreign Affairs says it has warned diplomatic missions to promptly evacuate their staff from the Ukrainian capital, Kyiv, in case Moscow launches a mass strike on the city in response to potential Ukrainian attempts to disrupt Russia's May 9 Victory Day commemorations. In a video posted on Telegram on Wednesday, Russian Foreign Ministry spokeswoman Maria Zakharova urged diplomats to heed the Defence Ministry's warning of a strike, issued on Monday, in the event of a Ukrainian attack during the commemorations of the Soviet Union's victory against Nazi Germany in World War II and a military parade in Red Square. Zakharova said that Ukrainian President Volodymyr Zelenskyy had made "aggressive and threatening statements" about disrupting the commemorations at a meeting of the European Political Community in Armenia on Monday. "Several EU countries were present," she said. In his remarks in Armenia, Zelenskyy noted a Russian announcement that the commemorations were being scaled down and taking place without military hardware for security reasons.

To stop children from bypassing its age checks, Meta is revamping its age-verification tools with an AI system that analyzes images and videos for "visual cues," such as height and bone structure. Meta is beefing up its age-verification mechanisms with an AI system that analyzes images and videos on Instagram and Facebook for "visual cues," such as height and bone structure, to identify and delete accounts of users under the age of 13. The company announced the move amid a wave of cases in which hundreds of children have managed to evade social network access restrictions, even through simple tricks such as drawing on a mustache. The new approach is part of a series of measures Meta adopted as part of an AI-based security strategy designed to correct the limitations of traditional methods, which rely heavily on self-reported age. With this change, the company seeks to reduce the ease with which minors access platforms that, in theory, are restricted to them.

What are Russia's gains from the Iran war? 'We are not losers; we are winners' Russia has begun rolling mobile internet shutdowns in Moscow and other cities, which authorities say is to counter drone threats. As Dmitry Medvedenko reports, the measures come ahead of the May 9 Victory Day parade, which has been scaled down this year due to security concerns.

As chaotic negotiations over the end of the Iran war continue, US negotiators think they have the framework for a deal in place. Now they just have to sell the president on it. President Donald Trump's negotiators face the arduous task of trying to convince the president that a deal he previously rejected is their best option in Iran . Last month, Trump initially gave his blessing for a so-called "cash for uranium" deal, under which the US would release around $20 billion in frozen funds in exchange for Iran handing over its stockpile of highly enriched uranium, sources familiar with the matter tell WIRED. Trump's negotiators, vice president JD Vance, special envoy Steve Witkoff, and Jared Kushner, Trump's son-in-law, received repeated approvals from the president while they were in Islamabad, giving them confidence a deal was close.

Russia ignores Ukraine's unilateral ceasefire and attacks kindergarten Volodymyr Zelensky has accused Russia of breaching a unilateral ceasefire announced by Ukraine by launching a wave of drone attacks on several cities. The Ukrainian president said Russia had carried out active hostilities and terrorist shelling, targeting the front line as well as firing dozens of drones and missiles at civilian areas. In the Sumy border region, one woman was killed when a kindergarten was hit on Wednesday morning, local authorities said. No children were present at the time. Earlier this week the two warring sides had announced rival unilateral ceasefires - with no agreement on their terms, length or monitoring.

Now, Activists Are Taking On Elon Musk's SpaceX IPO Activists, a leading labor union, and a big retirement fund are asking challenging questions about what's expected to be the largest-ever stock market debut. Elon Musk's SpaceX is facing protests against its expected initial public offering from some of the same advocacy groups that helped erase $600 billion from Tesla's market cap early last year. SpaceX's IPO is poised to be the largest ever, raising tens of billions of dollars for the Musk-founded company and valuing it above $2 trillion. If all goes as intended come June, the conglomerate that now owns a rocket manufacturer, a social media app, and an AI chatbot developer will instantly rank among the world's top 10 largest publicly-traded companies. On Wednesday, Randi Weingarten, president of the American Federation of Teachers, wrote to the US Securities and Exchange Commission urging it to scrutinize SpaceX's IPO preparations.

To stay or risk the'Road of Death' - Ukrainian civilians trapped in frontline city So, we're stuck here, says Ludmilla, over the phone from the rooftop of a fire-damaged house in southern Ukraine. People are trying their best to survive. Her frontline home city of Oleshky has, according to multiple accounts, been largely cut off from fresh supplies of food or medicine for months. Ludmilla describes being trapped there, and watching it decaying before her eyes. Ukraine's commissioner for human rights has warned of a humanitarian crisis.

We introduce a general framework that extends Bayesian inference by allowing the researcher to explicitly encode confidence in each source of uncertainty within the model. This mechanism provides a new handle for model design and regularisation control. Building on this framework, we develop a general approach for inducing sparsity in statistical models and illustrate its use in linear and logistic regression, as well as in Bayesian neural networks.

We develop graph-based methods for semi-supervised learning based on label propagation on a data similarity graph. When data is abundant or arrive in a stream, the problems of computation and data storage arise for any graph-based method. We propose a fast approximate online algorithm that solves for the harmonic solution on an approximate graph. We show, both empirically and theoretically, that good behavior can be achieved by collapsing nearby points into a set of local representative points that minimize distortion. Moreover, we regularize the harmonic solution to achieve better stability properties. We also present graph-based methods for detecting conditional anomalies and apply them to the identification of unusual clinical actions in hospitals. Our hypothesis is that patient-management actions that are unusual with respect to the past patients may be due to errors and that it is worthwhile to raise an alert if such a condition is encountered. Conditional anomaly detection extends standard unconditional anomaly framework but also faces new problems known as fringe and isolated points. We devise novel nonparametric graph-based methods to tackle these problems. Our methods rely on graph connectivity analysis and soft harmonic solution. Finally, we conduct an extensive human evaluation study of our conditional anomaly methods by 15 experts in critical care.
