Estimating the Robustness Radius for Randomized Smoothing with 100$\times$ Sample Efficiency

no code implementations26 Apr 2024 Emmanouil Seferis, Stefanos Kollias, Chih-Hong Cheng

Randomized smoothing (RS) has successfully been used to improve the robustness of predictions for deep neural networks (DNNs) by adding random noise to create multiple variations of an input, followed by deciding the consensus.

Prioritizing Corners in OoD Detectors via Symbolic String Manipulation

no code implementations16 May 2022 Chih-Hong Cheng, Changshun Wu, Emmanouil Seferis, Saddek Bensalem

We consider the definition of "in-distribution" characterized in the feature space by a union of hyperrectangles learned from the training dataset.

Unaligned but Safe -- Formally Compensating Performance Limitations for Imprecise 2D Object Detection

no code implementations10 Feb 2022 Tobias Schuster, Emmanouil Seferis, Simon Burton, Chih-Hong Cheng

We address a special sub-type of performance limitations: the prediction bounding box cannot be perfectly aligned with the ground truth, but the computed Intersection-over-Union metric is always larger than a given threshold.
