Differentially Private Fréchet Mean on the Manifold of Symmetric Positive Definite (SPD) Matrices with log-Euclidean Metric

no code implementations8 Aug 2022 Saiteja Utpala, Praneeth Vepakomma, Nina Miolane

In that spirit, the only geometric statistical query for which a differential privacy mechanism has been developed, so far, is for the release of the sample Fr\'echet mean: the \emph{Riemannian Laplace mechanism} was recently proposed to privatize the Fr\'echet mean on complete Riemannian manifolds.

Shrinkage Estimation of Higher Order Bochner Integrals

no code implementations13 Jul 2022 Saiteja Utpala, Bharath K. Sriperumbudur

We propose estimators that shrink the $U$-statistic estimator of the Bochner integral towards a pre-specified target element in the Hilbert space.

Quantile Regularization : Towards Implicit Calibration of Regression Models

no code implementations1 Jan 2021 Saiteja Utpala, Piyush Rai

We provide a detailed formal analysis of the \emph{side-effects} of Isotonic Regression when used for regression calibration.

Temperature Scaling for Quantile Calibration

no code implementations NeurIPS Workshop ICBINB 2020 Saiteja Utpala, Piyush Rai

Deep learning models are often poorly calibrated, i. e., they may produce overconfident predictions that are wrong, implying that their uncertainty estimates are unreliable.

Quantile Regularization: Towards Implicit Calibration of Regression Models

no code implementations28 Feb 2020 Saiteja Utpala, Piyush Rai

It is therefore desirable to have models that produce predictive uncertainty estimates that are reliable.
