Leaving No OOD Instance Behind: Instance-Level OOD Fine-Tuning for Anomaly Segmentation

NeurIPS 2025poster

Out-of-distribution (OOD) fine-tuning has emerged as a promising approach for anomaly segmentation. Current OOD fine-tuning strategies typically employ global-level objectives, aiming to guide segmentation models to accurately predict a large number of anomaly pixels. However, these strategies often…

RP-PGD: Boosting Segmentation Robustness with a Region-and-Prototype Based Adversarial Attack

AAAI 2025technical

Adversarial attack and defense have been extensively explored in classification tasks, but their study in semantic segmentation remains limited. Moreover, current attacks fail to act as strong underlying attacks for adversarial training (AT), making it difficult to achieve segmentation robustness ag…

Stop Diverse OOD Attacks: Knowledge Ensemble for Reliable Defense

AAAI 2025technical

Enhancing defense through model ensemble is an emerging trend, where the challenge lies in how to use ensemble knowledge to counter Out-of-Distribution (OOD) attacks. In this paper, we propose the Reliable Defense Ensemble (REE) to address this issue. REE optimizes the ensemble knowledge of models t…

Tip the Scales: Achieving Balance in Adversarial Examples Across Modalities

ICASSP 2025accepted

In the field of multimodal learning, controlling the training of unimodal encoders from different perspectives is a primary approach to addressing Training Imbalance. However, the inherent capacity limitations of the modality affect the model’s capability. Therefore, generating adversarial examples…

GenSeg: On Generating Unified Adversary for Segmentation

IJCAI 2024poster

Great advancements in semantic, instance, and panoptic segmentation have been made in recent years, yet the top-performing models remain vulnerable to imperceptible adversarial perturbation. Current attacks on segmentation primarily focus on a single task, and these methods typically rely on iterati…
