Dynamic Global Sensitivity for Differentially Private Contextual Bandits

no code implementations30 Aug 2022 Huazheng Wang, David Zhao, Hongning Wang

We provide a rigorous theoretical analysis over the amount of noise added via dynamic global sensitivity and the corresponding upper regret bound of our proposed algorithm.

Likelihood-Free Frequentist Inference: Bridging Classical Statistics and Machine Learning for Reliable Simulator-Based Inference

2 code implementations8 Jul 2021 Niccolò Dalmasso, Luca Masserano, David Zhao, Rafael Izbicki, Ann B. Lee

In this work, we propose a unified and modular inference framework that bridges classical statistics and modern machine learning providing (i) a practical approach to the Neyman construction of confidence sets with frequentist finite-sample coverage for any value of the unknown parameters; and (ii) interpretable diagnostics that estimate the empirical coverage across the entire parameter space.

MD-split+: Practical Local Conformal Inference in High Dimensions

no code implementations7 Jul 2021 Benjamin LeRoy, David Zhao

Quantifying uncertainty in model predictions is a common goal for practitioners seeking more than just point predictions.
