Balancing utility and scalability in metric differential privacy

UAI 2022poster

Metric differential privacy (mDP) is a modification of differential privacy that is more suitable when records can be represented in a general metric space, such as text data represented as word embed- dings or geographical coordinates on a map. We consider the task of releasing elements of the metr…

Reconstructing Test Labels from Noisy Loss Functions

AISTATS 2022poster

Machine learning classifiers rely on loss functions for performance evaluation, often on a private (hidden) dataset. In a recent line of research, label inference was introduced as the problem of reconstructing the ground truth labels of this private dataset from just the (possibly perturbed) cross-…

Label Inference Attacks from Log-loss Scores

ICML 2021oral

Log-loss (also known as cross-entropy loss) metric is ubiquitously used across machine learning applications to assess the performance of classification algorithms. In this paper, we investigate the problem of inferring the labels of a dataset from single (or multiple) log-loss score(s), without any…

Ignorance is Not Bliss: An Analysis of Central-Place Foraging Algorithms

IROS 2019poster

Central-place foraging (CPF) is a canonical task in collective robotics with applications to planetary exploration, automated mining, warehousing, and search and rescue operations. We compare the performance of three Central-Place Foraging Algorithms (CPFAs), variants of which have been shown to wor…
