Statistical Limits and Efficient Algorithms for Differentially Private Federated Learning
Auddy, Arnab, Peng, Xiangni, Paul, Subhadeep
Federated Learning is a leading framework for training ML and AI models collaboratively across numerous user devices or databases. We study the trade-offs among estimation accuracy, privacy constraints, and communication cost for differentially private (DP) federated M estimation. The two standard methods in the literature are FedAvg, which may suffer from high federation bias, and FedSGD, which can incur high communication cost. Aimed at improving accuracy at a reduced communication cost, we propose FedHybrid, which uses FedSGD starting with an improved initialization by the FedAvg estimator. We propose FedNewton, which averages local Newton iterations to reduce bias in FedAvg, achieving an estimation accuracy comparable to FedSGD with much fewer communication rounds when the number of clients grows sufficiently slowly. We establish finite sample upper bounds on the mean-squared error rates of the DP versions of these estimators as functions of the number of clients, local sample sizes, privacy budget, and number of iterations. We further derive a minimax lower bound on the MSE of any iterative private federated procedure that provides a benchmark to assess the optimality gap of these methods. We numerically evaluate our methods for training a logistic regression and a neural network on the computer vision datasets MNIST and CIFAR-10.
Some Women Are Obsessively Testing Their Vaginas to Optimize Them
Biohacker Bryan Johnson recently bragged about his girlfriend's "top 1%" vagina as the at-home vaginal microbiome test industry is thriving. Farrah was fed up with her vagina . For the past two years, the 29-year-old dancer from Ohio had been dealing with severe pelvic pain and vaginal odor. "It was like 8/10, horrible core pain," she says. When she visited doctors, she told them what she thought the culprit was: an allergic reaction to soy oil in a vat of water she'd swam in during a pirate-themed dinner theater performance. But they didn't believe her.
Taylor Swift Wants to Trademark Her Likeness. These TikTok Deepfake Ads Show Why
Researchers show scammers are using AI-manipulated footage of celebrity interviews to trick users into sharing their personal data. Last week, Taylor Swift filed a trio of trademark applications to protect her image and voice. One is meant to cover a well-known photograph of the pop singer holding a pink guitar during a concert on her record-breaking Eras tour, while the two sound trademarks are for simple identifying phrases: "Hey, it's Taylor Swift" and "Hey, it's Taylor." The move comes as AI deepfakes continue to proliferate across social media. Any individual stands to have their likeness exploited in the creation of nonconsensual AI-generated material; earlier this month, an Ohio man was the first person convicted under a new federal law criminalizing "intimate" visual deceptions of this sort.

I pride myself on getting it in good in sports betting, which is poker slang for making a plus-expected value bet before all the cards are dealt. Well, it's getting harder and harder to do that in the 2026 Whether it be the NFL executives telling teams to keep their draft boards more private because we can now legally gamble on this stuff, or the sportsbooks are just putting up sharper numbers. Either way, it's tough for schnooks like me to profit off the NFL draft nowadays.
