DRIFT: Divergent Response in Filtered Transformations for Robust Adversarial Defense

ICLR 2026poster

Deep neural networks remain highly vulnerable to adversarial examples, and most defenses collapse once gradients can be reliably estimated. We identify \emph{gradient consensus}—the tendency of randomized transformations to yield aligned gradients—as a key driver of adversarial transferability. Atta…

TriQDef: Disrupting Semantic and Gradient Alignment to Prevent Adversarial Patch Transferability in Quantized Neural Networks

ICLR 2026poster

Quantized Neural Networks (QNNs) are widely deployed in edge and resource-constrained environments for their efficiency in computation and memory. While quantization distorts gradient landscapes and weakens pixel-level attacks, it offers limited robustness against patch-based adversarial attacks—loc…

ODDR: Outlier Detection & Dimension Reduction Based Defense Against Adversarial Patches

ICCV 2025poster

Adversarial attacks present a significant challenge to the dependable deployment of machine learning models, with patch-based attacks being particularly potent. These attacks introduce adversarial perturbations in localized regions of an image, deceiving even well-trained models. In this paper, we p…

SSAP: A Shape-Sensitive Adversarial Patch for Comprehensive Disruption of Monocular Depth Estimation in Autonomous Navigation Applications

IROS 2024poster

Monocular depth estimation (MDE) has advanced significantly, primarily through the integration of convolutional neural networks (CNNs) and more recently, Transformers. However, concerns about their susceptibility to adversarial attacks have emerged, especially in safety-critical domains like autonom…
