Federated Learning (FL) offers a decentralized solution that allows collaborative local model training and global aggregation, thereby protecting data privacy. In conventional FL frameworks, data privacy is typically preserved under the assumption that local data remains absolutely private, whereas the mobility of clients is frequently neglected in explicit modeling. In this paper, we propose a hierarchical federated learning framework based on the social network with mobility namely HFL-SNM that considers both data sharing among clients and their mobility patterns. Under the constraints of limited resources, we formulate a joint optimization problem of resource allocation and client scheduling, which objective is to minimize the energy consumption of clients during the FL process. In social network, we introduce the concepts of Effective Data Coverage Rate and Redundant Data Coverage Rate. We analyze the impact of effective data and redundant data on the model performance through preliminary experiments. We decouple the optimization problem into multiple sub-problems, analyze them based on preliminary experimental results, and propose Dynamic Optimization in Social Network with Mobility (DO-SNM) algorithm. Experimental results demonstrate that our algorithm achieves superior model performance while significantly reducing energy consumption, compared to traditional baseline algorithms.

Membership in ACM includes a subscription to Communications of the ACM (CACM), the computing industry's most trusted source for staying connected to the world of advanced computing. Can AI Expand the Human Mind? LLMs could represent a new layer of human cognition, which researchers call'System 0.' Giuseppe Riva first started to think about the role that artificial intelligence (AI) can play in human cognition when he and a colleague were trying to find someplace to have dinner in Los Angeles. Both pulled out their phones and started perusing Google Maps for suggestions of nearby restaurants. Riva quickly noticed that the list of possibilities on his phone was very different from what his companion was seeing.

Venture capitalist Alexa von Tobel is ready to bet on quantum computing--starting with hardware. Alexa von Tobel is fully aware that her big bet on quantum computing may never pay off. "The risk of being too early is a real risk," she says. She's speaking to me via Zoom from the New York City office of Inspired Capital, the early-stage venture capital firm she runs with former US commerce secretary Penny Pritzker. In addition to personally investing in blue-chip brands like Uber and Airtable, von Tobel has backed a number of AI startups through Inspired Capital, including BrightAI (a platform that monitors critical infrastructure) and PreemptiveAI (a startup building a foundation model to map human physiology and predict health outcomes).

The National Hurricane Center (NHC) revealed their updated tracks for a pair of tropical disturbances brewing in the Atlantic, giving both a high likelihood of turning into named storms within seven days . One of these threatening weather systems, currently dubbed Invest 94L, is expected to form right off the coast of Florida . The other potential storm, called Invest 93L, has been developing in the middle of the Atlantic and forecasters unveiled an initial path that could take it towards the Carolinas by the end of the week.

But Amazon's'Fresh' shopping concept - which uses AI to track customers - may instead be remembered as a failed experiment in mass surveillance. The tech giant has announced that it has made the'difficult decision' to close all 19 Amazon Fresh stores in the UK - putting up to 250 workers at risk. Amazon claims the closures are the result of a'thorough evaluation of business operations and the very substantial growth opportunities in online delivery'.

How Taylor Swift has ditched her Southern drawl in favour of a northern American accent, revealed In the 19 years since she released her first song, Taylor Swift's music been through several transitions, changing from country, to pop, to indie folk, and almost every genre in between. Now, a study has revealed how it's not just Swift's music that has evolved. Scientists from the University of Minnesota say the chart-topping singer's accent has also changed over time. In their study, the team analysed years of Swift's recorded interviews to track how her dialect has transformed.

Gravitational waves are ripples in the fabric of space and time, usually created when massive, dense objects like black holes collide. But at less than a tenth of a second long, this sudden burst was far shorter than the drawn-out chirps normally produced by merging black holes. Now, researchers think this strange signal, dubbed GW190521, could have arrived from a parallel universe.

Should AI continue to be driven by a single paradigm, or does real progress lie in combining the strengths and weaknesses of many? Professor Luc De Raedt of KU Leuven has spent much of his career persistently addressing this question. Through pioneering work that bridges logic, probability, and machine learning, he has helped shape the field of neurosymbolic AI. In our conversation at IJCAI 2025 in Montreal, he spoke about what continues to fascinate him in this line of research, how he responds to criticisms of neurosymbolic AI, and why reconciling multiple paradigms is such an exciting challenge. Hello Professor De Raedt, thank you very much for joining me.

The Signal Foundation president recalls where she was when she heard Trump cabinet officials had added a journalist to a highly sensitive group chat. In March of this year, Meredith Whittaker was at her kitchen table in Paris when Signal, the encrypted messaging service she runs, suddenly became an international headline . A colleague sent their group chat the story ricocheting across the globe: "The Trump Administration Accidentally Texted Me Its War Plans." Of course, you know the rest: In the piece, The Atlantic's editor in chief, Jeffrey Goldberg, detailed how he'd been added to a Signal chat about an upcoming military operation in Yemen. Over the following days and weeks, the incident would become known as " SignalGate "--and created a legitimate risk that the fallout would cause people to question Signal's security, instead of pointing their fingers at the profoundly dubious op-sec of senior-level Trump officials. In fact, Signal's user numbers grew by leaps and bounds, both in the US and around the world. It's growth that, Whittaker thinks, is coming at a time when "people are feeling in a much deeper, much more personal way why privacy might be important." On this week's episode of, I talked to Whittaker, who also cofounded the AI Now Institute, about the aftermath of SignalGate, the trajectory of artificial intelligence, and the tech industry's current relationship with politics. Nice to see you, Katie. Nice to see you, too. Brace yourself, we always start these conversations with a little warmup, so I'm going to ask you some very fast questions. I knew you were gonna say that. What's the weirdest AI application you've ever seen? A chatbot that pretends to be your friend.
