Blackbox Attacks via Surrogate Ensemble Search

1 code implementation7 Aug 2022 Zikui Cai, Chengyu Song, Srikanth Krishnamurthy, Amit Roy-Chowdhury, M. Salman Asif

We also show that the perturbations generated by our proposed method are highly transferable and can be adopted for hard-label blackbox attacks.

Connecting the Dots: Detecting Adversarial Perturbations Using Context Inconsistency

no code implementations ECCV 2020 Shasha Li, Shitong Zhu, Sudipta Paul, Amit Roy-Chowdhury, Chengyu Song, Srikanth Krishnamurthy, Ananthram Swami, Kevin S. Chan

There has been a recent surge in research on adversarial perturbations that defeat Deep Neural Networks (DNNs) in machine vision; most of these perturbation-based attacks target object classifiers.

Non-Uniform Subset Selection for Active Learning in Structured Data

1 code implementation Computer Vision and Pattern Recognition (CVPR) 2017 Sujoy Paul, Jawadul H. Bappy, Amit Roy-Chowdhury

We construct a graph from the unlabeled data to represent the underlying structure, such that each node represents a data point, and edges represent the inter-relationships between them.

Adaptive Algorithm and Platform Selection for Visual Detection and Tracking

no code implementations21 May 2016 Shu Zhang, Qi Zhu, Amit Roy-Chowdhury

In this paper, we focus on this problem and propose a framework to adaptively select the "best" algorithm-parameter combination and the computation platform under performance and cost constraints at design time, and adapt the algorithms at runtime based on real-time inputs.
