GPUs have significantly accelerated first-order methods for large-scale optimization, especially in continuous optimization. However, this success has not transferred cleanly to problems with discrete variables, combinatorial structure, and nonlinear objectives, such as certifying optimal solutions for cardinality-constrained generalized linear models. Major challenges include the sequential processing of heterogeneous nodes in branch and bound (BnB) and frequent data movement between the CPU and GPU. We propose a simple, generic, and modular CPU--GPU framework that processes multiple BnB nodes in batches on GPUs. The framework is built around a small set of GPU-efficient routines and uses padding together with lightweight custom kernels to handle irregular node data structures. Experiments show one to two orders of magnitude speedups and zero optimality gap on challenging instances. The framework can also be extended to collect the entire Rashomon set, enabling downstream statistical analysis such as variable-importance analysis and model selection under secondary user-specific measures (e.g., AUC in classification).

Symbolic regression with genetic programming (GPSR) may suffer from overfitting and structural bloat, especially when noise is present. In this paper we evaluate description length (DL) and fractional Bayes factor (FBF) criteria as principled, data-efficient alternatives to heuristics for selecting compact expressions that generalise well. We implement DL using a Fisher-information-based parameter encoding and compare it to AIC and BIC across multiple datasets, including noisy synthetic benchmarks and real-world regression problems. We study three search/selection strategies: (i) multi-objective search for accuracy and program length followed by DL/FBF selection; (ii) multi-objective search using DL directly as an objective; and (iii) single-objective optimisation with DL/FBF as the fitness. Across datasets we find that DL/FBF post-selection improves test performance compared to AIC/BIC baseline and that BIC in combination with the same function complexity penalty from DL/FBF produces similar results. In contrast, using DL/FBF directly as a fitness function in single-objective GPSR frequently induces premature convergence to overly simple models. We conclude with practical guidance for using DL/FBF as robust model-selection tools in genetic programming workflows.

We propose a new framework for generative modeling based on a discrete-time stochastic control formulation of measure transport. Adapting classic results from control theory, we formulate our problem as a linear program whose dual variables correspond to the \emph{optimal value function} of the control problem, which directly encodes the optimal control policy. Exploiting this LP formulation, we develop an efficient simulation-free primal-dual algorithm for computing approximately optimal value functions and the associated \emph{value-driven transport} (VDT) policies which approximate the true optimal policy. We show that well-trained VDT policies enjoy numerous favorable properties in comparison with other state-of-the-art methods based on flows, diffusions, or Schrödinger bridges: they lead to straight transport paths which can be simulated quickly and robustly, and can be enhanced in all the same ways as diffusion and flow-based models (e.g., conditional generation, classifier-free guidance, unpaired data-to-data translation are all easy to incorporate). We evaluate our methodology in a range of experiments, with results that indicate strong performance and good potential for scalability.

'Creepy' Listening Tool for Targeted Ads Didn't Actually Work, FTC Says Three firms will pay nearly $1 million for selling "Active Listening" technology that they claimed tapped people's phones for advertising. The FTC alleges the "tech" was just pricey email lists. The Federal Trade Commission announced on Thursday that Cox Media Group and two other marketing companies, MindSift LLC and 1010 Digital Works, have agreed to collectively pay nearly $1 million to settle allegations that they deceived their customers--other businesses--by claiming that they could help target ads based on audio recordings collected from consumers' smart devices via a marketing service called Active Listening. In a statement to WIRED, a spokesperson for CMG says, "We are pleased to have this matter resolved. Our local marketing team relied on marketing materials provided to us by a third-party vendor about their product. We withdrew the materials expeditiously and stopped further use of the product."

This isn't going to be a poorly produced amateur-level movie thrown together with someone who doesn't know what they're doing. It's also not a sex tape, for the folks who can't get their act together.

He further discusses the development of artificial eggs that could revive dead species. I'll be honest with you guys, I don't know what to make of my feelings toward artificial intelligence, because my mood on the subject changes by the day.

Meta Is in Crisis, Google Search's Makeover, and AI Gets Booed by Graduates This week on, the team discusses Meta's recent layoffs and what they've been hearing from employees about the increasingly grim vibes at the company. They also talk about Elon Musk losing his lawsuit against OpenAI and share highlights from Google's annual conference--including an ambitious AI vision to change how people search the web. Finally, what do recent college graduates and women whose spouses work in AI have in common? Google Search Goes Agentic--and Doesn't Need You Anymore Write to us at [email protected] . You can always listen to this week's podcast through the audio player on this page, but if you want to subscribe for free to get every episode, here's how: If you're on an iPhone or iPad, open the app called Podcasts, or just tap this link . We spoke to more than a dozen employees and it turns out the job cuts are far from the only reason why Meta employees are really going through it. He lost his lawsuit against Sam Altman and OpenAI in really as full a way as you can, as dramatically as possible. I know, Zoë, you're looking forward to talking about that. We're going to get into why young adults might be using AI, but they have very complicated feelings about it. And later in the show, we're going to hear about why women married to AI bros have had enough . This week, the company is letting go of roughly 10 percent of its workforce, which is about 8,000 employees total. It's the latest round of job cuts, adding to the roughly 25,000 jobs that have been cut in the past few years as part of Mark Zuckerberg's Year of Efficiency that started in 2023 and now the latest AI-forward workplace, which he is trying to develop and impose. And while these latest cuts are not as big as some of the rounds of layoffs that have already happened, they're getting a ton of attention because Mark Zuckerberg, the CEO, has said that the reason they're happening, in part at least, in large part, is because the company is spending so much money on AI and data centers.

Spotify said the new tool could create an extra stream of income for artists and songwriters. Spotify said the new tool could create an extra stream of income for artists and songwriters. Spotify and Universal Music Group have agreed on a deal that will allow subscribers to generate song covers and remixes using artificial intelligence. The licensing agreement is the first time the Swedish streaming company will allow listeners to use AI to create content through its platform. It is expected to be in the form of a paid add-on available on Spotify's app.

Why the world's banks are so worried about Anthropic's latest AI model The legendary American bank robber Willie Sutton spent 40 years robbing banks because, as he claimed in his autobiography, he loved doing it. And when asked why he chose banks of all places to rob, he allegedly replied "Because that's where the money is." Back in 2017, I wrote a book predicting it wasn't just lovable rogues like Sutton who would soon be robbing banks, but artificial intelligence (AI). That day, it appears, could now be about to arrive. Banks around the world are seriously worried cyber criminals will soon take advantage of the latest advances in AI to try to rob them.
