Breakthroughs, discoveries, and DIY tips sent every weekday. If you recently received a voice message from an unusual number claiming to be your local congressperson, it's probably a scam. The FBI's crime division issued a warning this week about a new scheme in which bad actors use text messages and AI-generated voice clones to impersonate government officials. The scammers try to build a sense of connection with their target and eventually convince them to click on a malicious link that steals valuable login credentials. This scam is just the latest in a series of evolving attacks using convincing generative AI technology to trick people.

This paper provides a theoretical study of deep neural function approximation in reinforcement learning (RL) with the ϵ-greedy exploration under the online setting. This problem setting is motivated by the successful deep Q-networks (DQN) framework that falls in this regime. In this work, we provide an initial attempt on theoretical understanding deep RL from the perspective of function class and neural networks architectures (e.g., width and depth) beyond the "linear" regime. To be specific, we focus on the value based algorithm with the ϵ-greedy exploration via deep (and two-layer) neural networks endowed by Besov (and Barron) function spaces, respectively, which aims at approximating an α-smooth Q-function in a d-dimensional feature space.

Although their specs and features are updated every year, Apple's iPhones maintain the same general size and shape. But according to a new report, the tech giant is preparing a radical new form factor for one of its upcoming handsets. Apple tipster Mark Gurman claims the trillion-dollar tech company is working on a'mostly glass, curved iPhone'. The device will come'without any cutouts in the display', he claims, such as a notch at the top or a small circle for a front-facing camera. It will hit the shelves in a couple of years to mark 20 years since the very first iPhone went on sale – June 29, 2007.

Having your favourite TV show or movie interrupted by adverts is already frustrating, but things could soon be getting worse for Netflix users. At its'Upfront' event on Wednesday, the streaming giant revealed that it would be incorporating adverts made with'generative AI'. Arriving in 2026, these AI-generated adverts will begin to appear not only during mid-content breaks but also when users press pause. And the only way to get rid of these annoying intrusions will be to pay for the more expensive ad-free subscriptions. But in a further twist, Netflix says AI would be used'instantly marry advertisers' ads with the worlds of our shows'.

Claire chatted to Lerrel Pinto from New York University about using machine learning to train robots to adapt to new environments. Lerrel Pinto is an Assistant Professor of Computer Science at New York University (NYU). His research is aimed at getting robots to generalize and adapt in the messy world we live in. His lab focuses broadly on robot learning and decision making, with an emphasis on large-scale learning (both data and models); representation learning for sensory data; developing algorithms to model actions and behaviour; reinforcement learning for adapting to new scenarios; and building open-source, affordable robots.

A couple of months ago, Vice-President J. D. Vance made an appearance in Washington at the American Dynamism summit, an annual event put on by the venture-capital firm Andreessen Horowitz. Members of Congress, startup founders, investors, and Defense Department officials sat in the audience. They gave Vance a standing ovation as he walked onstage, while Alabama's "Forty Hour Week (For a Livin')" played in the background. "You're here, I hope, because you love your country," Vance told the crowd. "You love its people, the opportunities that it's given you, and you recognize that building things--our capacity to create new innovation in the economy--cannot be a race to the bottom."

Larry Niven is one of the biggest names in the history of science fiction, and it was a privilege to interview him via Zoom at his home in Los Angeles recently. His 1970 novel Ringworld is the latest pick for the New Scientist Book Club, but he has also written a whole space-fleet-load of novels and short stories over the years, including my favourite sci-fi of all time, A World Out of Time. At 87 years of age, he is very much still writing. I spoke to him about Ringworld, his start in sci-fi, his favourite work over the years, his current projects and whether he thinks humankind will ever leave this solar system. This is an edited version of our conversation.

We will add the proof for the same in the revision. SDPs deliver mode estimates of practically the same quality across various coupling strengths.
