The geometric median, an instrumental component of the secure machine learning toolbox, is known to be effective when robustly aggregating models (or gradients), gathered from potentially malicious (or strategic) users. What is less known is the extent to which the geometric median incentivizes dishonest behaviors. This paper addresses this fundamental question by quantifying its strategyproofness. While we observe that the geometric median is not even approximately strategyproof, we prove that it is asymptotically $\alpha$-strategyproof: when the number of users is large enough, a user that misbehaves can gain at most a multiplicative factor $\alpha$, which we compute as a function of the distribution followed by the users. We then generalize our results to the case where users actually care more about specific dimensions, determining how this impacts $\alpha$. We also show how the skewed geometric medians can be used to improve strategyproofness.

Doctors believe Artificial Intelligence is now saving lives, after a major advancement in breast cancer screenings. A.I. is detecting early signs of the disease, in some cases years before doctors would find the cancer on a traditional scan. Meet Ezra, the full-body cancer screener that just might save your life. Combining MRI imaging technology with artificial intelligence, Ezra scans for possible cancer in the human body in up to 13 organs. It also monitors for hundreds of other conditions, such as brain aneurysms or fatty liver disease.

Fox News congressional correspondent Aishah Hasnie has the latest on an alleged drone strike attack at the Kremlin and lawmakers' concerns about fentanyl and artificial intelligence on'Special Report.' FIRST ON FOX: Former President Trump said he would deploy military assets to fight the fentanyl crisis and "inflict maximum damage" on cartel operations if elected in 2024, and he would seek the death penalty to convicted drug dealers and human traffickers. Trump outlined his proposed policies for ending drug addiction in America in a new campaign video obtained by Fox News Digital on Thursday. "For three decades before my election, drug overdose deaths increased every single year. Under my leadership, we took the drug and fentanyl crisis head on, and we achieved the first reduction in overdose deaths in more than 30 years," Trump said in the video.

When Teslas are in self-driving mode, they've been recorded crossing into oncoming traffic and hitting parked cars. But what would happen if an 80,000-pound, 18-wheel driverless truck suddenly went off the rails? That's an experiment some California legislators aren't ready to run. They argue that the state Department of Motor Vehicles has so badly mishandled the driverless car industry that it can't be trusted to oversee big rigs barreling down the highways autonomously. AB 316 -- which would wrest control of driverless truck testing and deployment from the DMV and require human drivers in the cab for at least five years while a safety record is collected -- passed in the Assembly on Wednesday.

The National Eating Disorders Collaboration of Australia warns that increasing focus on weight or body shape puts one at greater risk of an eating-disorder relapse. Other warning signs include repeated self-weighing and counting calories, according to the group, which advises the Australian government. The mention of specific weights, measurements, weight loss and quantities around food should also be avoided around people with a history of eating disorders, according to the InsideOut Institute at the University of Sydney.

Center for AI Safety Director Dan Hendrycks explains concerns about how the rapid growth of artificial intelligence could impact society. A federal agency is pondering whether artificial intelligence might someday be used to help the government identify duplicative or overly burdensome federal rules that need to be cut back. But officials are already hearing from skeptics who doubt AI will ever be powerful enough to wade through and understand the hundreds of thousands of pages of detailed federal rules. The Administrative Conference of the United States (ACUS) is an independent federal agency that works to increase the efficiency and fairness of regulations. In early May, ACUS released a report it commissioned on how AI and other algorithmic tools might be used to conduct retrospective reviews of federal rules to improve them.

People in Texas sounded off on AI job displacement, with half of the people who spoke to Fox News convinced that the tech will rob them of work. Humans have historically been excellent at identifying faces and photos compared to computers, but the advent of artificial intelligence-generated photos is throwing a curveball at humans, according to a new study that examines how people perceive fake images versus real ones. Tech experts have been warning that hyperrealistic images generated by AI could lead to the proliferation of misinformation online and cybersecurity issues. Last month, for example, panic spread after an AI-generated photo that apparently showed an explosion at the Pentagon went viral, leading to the stock market taking a short dip. Researchers in Australia examined how human brains perceive and differentiate realistic AI-generated photos using both behavioral testing and neuroimaging experiments.

Bloomberg – Nvidia CEO Jensen Huang is heading to China to meet with technology executives in the world's biggest chip market, despite rising tensions between Washington and Beijing, according to people familiar with the matter. Huang, who headlined a trade show in Taiwan this week, plans to travel to China for the first time in years in June, said the people, who asked not to be identified because his schedule is private. Companies on his itinerary include gaming leader Tencent Holdings and TikTok-owner ByteDance, one of the people said. Nvidia is emerging as a critical player in the booming field of artificial intelligence, but its position in China has been complicated by geopolitics. U.S. sanctions unveiled by the Biden administration last year prevent the semiconductor company from selling its most advanced AI chipsets to Chinese customers, including Tencent and ByteDance.

Biden administration officials are divided over how aggressively new artificial intelligence tools should be regulated -- and their differences are playing out this week in Sweden. Some White House and Commerce Department officials support the strong measures proposed by the European Union for AI products such as ChatGPT and Dall-E, people involved in the discussions said. Meanwhile, U.S. national security officials and some in the State Department say aggressively regulating this nascent technology will put the nation at a competitive disadvantage, according to the people, who asked not to be identified because the information isn't public. This dissonance has left the U.S. without a coherent response during this week's U.S.-EU Trade and Technology Council gathering in Sweden to the EU's plan to subject generative AI to additional rules. This could be due to a conflict with your ad-blocking or security software.

Hoover Institution senior fellow Victor Davis Hanson provides analysis into the corporate world forging trade deals with China amid growing tensions on'The Story.' Chinese President Xi Jinping on Tuesday advised his national security team to prepare for the worst-case scenario amid an increase in threats -- both internally and externally -- to the nation. The comments, carried on the state-run Xinhua News Agency, came during a meeting of the Chinese Communist Party's National Security Commission. FILE: China's President Xi Jinping arrives to attend the APEC Economic Leaders Meeting during the Asia-Pacific Economic Cooperation, APEC summit, Nov. 19, 2022, in Bangkok, Thailand. Xi said the "complexity and difficulty of the national security issues we now face have increased significantly." China must "adhere to bottom-line thinking and worst-case scenario thinking, and get ready to undergo the major tests of high winds and rough waves, and even perilous, storm seas," he said.
