Researchers have developed DP-GRAMS, a novel method for differentially private nonparametric modal learning, which addresses the challenge of estimating density modes under strict privacy constraints. The proposed technique utilizes a mean-shift inspired approach with higher-order kernels and noisy gradient ascent to recover modes of multivariate distributions. Extensions include DP-PMS for private modal regression and DP-GRAMS-C for clustering, with experimental results demonstrating competitive privacy-utility trade-offs. AI
