AntiStyler: Defending Object Detection Models Against Adversarial Patch Attacks Using Style Removal

CVPR 2026

Adversarial patch attacks pose a significant threat to the reliability of object detection (OD) models, particularly in real-time security applications. Although several defenses have been proposed, they often suffer from two limitations: 1) reduced performance on benign images, and 2) impractical p

DIESEL: A Lightweight Inference-Time Safety Enhancement for Language Models

ACL 2025finding

Large language models (LLMs) have demonstrated impressive performance across a wide range of tasks, including open-ended dialogue, driving advancements in virtual assistants and other interactive systems. However, these models often generate outputs misaligned with human values, such as ethical norm…

Gradient Inversion of Multimodal Models

ICML 2025poster

Federated learning (FL) enables privacy-preserving distributed machine learning by sharing gradients instead of raw data. However, FL remains vulnerable to gradient inversion attacks, in which shared gradients can reveal sensitive training data. Prior research has mainly concentrated on unimodal tas…

KDAT: Inherent Adversarial Robustness via Knowledge Distillation with Adversarial Tuning for Object Detection Models

AAAI 2025technical

Adversarial patches pose a significant threat to computer vision models' integrity, decreasing the accuracy of various tasks, including object detection (OD). Most existing OD defenses exhibit a trade-off between enhancing the model's adversarial robustness and maintaining its performance on benign…

Manifold Induced Biases for Zero-shot and Few-shot Detection of Generated Images

ICLR 2025poster

Distinguishing between real and AI-generated images, commonly referred to as 'image detection', presents a timely and significant challenge. Despite extensive research in the (semi-)supervised regime, zero-shot and few-shot solutions have only recently emerged as promising alternatives. Their main…

MONTAGE: Monitoring Training for Attribution of Generative Diffusion Models

ECCV 2024poster

"Diffusion models, which revolutionized image generation, are facing challenges related to intellectual property. These challenges arise when a generated image is influenced by copyrighted images from the training data, a plausible scenario in internet-collected data. Hence, pinpointing influential…
