Researchers have developed a new differentially private algorithm for weighted empirical risk minimization (wERM), a generalization of standard ERM that accounts for varying individual contributions to the objective function. This novel approach provides formal privacy guarantees and derives both empirical and population excess risk bounds. The framework is particularly applicable to privacy-preserving methods for individualized treatment rules, such as outcome-weighted learning (OWL), and has demonstrated robust performance in simulations and real-world data experiments.
