Researchers have developed a new method for density estimation under relaxed local differential privacy, utilizing a symmetrized Gamma distribution for noise addition. This approach achieves a faster estimation rate for Sobolev smooth functions compared to traditional $\alpha$-LDP methods, bringing it closer to non-private minimax rates. The technique has been implemented in a neural network estimator that avoids adding extra noise during optimization, showing significant improvements over Laplace and private-SGD mechanisms in numerical results.
