Generative Posterior Networks for Approximately Bayesian Epistemic Uncertainty Estimation

no code implementations29 Dec 2023 Melrose Roderick, Felix Berkenkamp, Fatemeh Sheikholeslami, Zico Kolter

In many real-world problems, there is a limited set of training data, but an abundance of unlabeled data.

Data Augmentation for Improving Tail-traffic Robustness in Skill-routing for Dialogue Systems

no code implementations7 Jun 2023 Ting-Wei Wu, Fatemeh Sheikholeslami, Mohammad Kachuee, Jaeyoung Do, Sungjin Lee

Large-scale conversational systems typically rely on a skill-routing component to route a user request to an appropriate skill and interpretation to serve the request.

You Only Query Once: Effective Black Box Adversarial Attacks with Minimal Repeated Queries

no code implementations29 Jan 2021 Devin Willmott, Anit Kumar Sahu, Fatemeh Sheikholeslami, Filipe Condessa, Zico Kolter

In this work, we instead show that it is possible to craft (universal) adversarial perturbations in the black-box setting by querying a sequence of different images only once.

Provably robust classification of adversarial examples with detection

1 code implementation ICLR 2021 Fatemeh Sheikholeslami, Ali Lotfi, J Zico Kolter

Adversarial attacks against deep networks can be defended against either by building robust classifiers or, by creating classifiers that can \emph{detect} the presence of adversarial perturbations.

Certified robustness against physically-realizable patch attack via randomized cropping

no code implementations1 Jan 2021 Wan-Yi Lin, Fatemeh Sheikholeslami, Jinghao Shi, Leslie Rice, J Zico Kolter

Our method improves upon the current state of the art in defending against patch attacks on CIFAR10 and ImageNet, both in terms of certified accuracy and inference time.

Reinforcement Learning for Caching with Space-Time Popularity Dynamics

no code implementations19 May 2020 Alireza Sadeghi, Georgios B. Giannakis, Gang Wang, Fatemeh Sheikholeslami

With the tremendous growth of data traffic over wired and wireless networks along with the increasing number of rich-media applications, caching is envisioned to play a critical role in next-generation networks.

Minimum Uncertainty Based Detection of Adversaries in Deep Neural Networks

no code implementations5 Apr 2019 Fatemeh Sheikholeslami, Swayambhoo Jain, Georgios B. Giannakis

The effectiveness of the novel detectors in the context of competing alternatives is highlighted through extensive tests for various types of adversarial attacks with variable levels of strength.

Reinforcement Learning for Adaptive Caching with Dynamic Storage Pricing

no code implementations17 Dec 2018 Alireza Sadeghi, Fatemeh Sheikholeslami, Antonio G. Marques, Georgios B. Giannakis

Under this generic formulation, first by considering stationary distributions for the costs and file popularities, an efficient reinforcement learning-based solver known as value iteration algorithm can be used to solve the emerging optimization problem.

Optimal and Scalable Caching for 5G Using Reinforcement Learning of Space-time Popularities

no code implementations19 Jul 2017 Alireza Sadeghi, Fatemeh Sheikholeslami, Georgios B. Giannakis

To intelligently prefetch, each SB must learn what and when to cache, while taking into account SB memory limitations, the massive number of available contents, the unknown popularity profiles, as well as the space-time popularity dynamics of user file requests.
