New framework uses JLT for differentially private variable selection

Researchers have developed a new framework for high-dimensional variable selection that maintains differential privacy. This method uses the Johnson-Lindenstrauss Transform (JLT) to privatize data matrices, preserving covariate relationships while adhering to $(\epsilon,\delta)$-differential privacy constraints. The approach theoretically guarantees control over the False Discovery Rate (FDR) and analyzes the trade-offs between privacy and statistical power, demonstrating that JLT outperforms traditional noise injection methods in maintaining power under strict privacy budgets.
