AAKR: Adversarial Attack-based Knowledge Retention for Continual Semantic Segmentation

AAAI 2025technical

In the context of Continual Semantic Segmentation (CSS), replay-based methods tend to achieve better performance than knowledge distillation-based ones, as the former utilizes additional data to transfer old knowledge. However, this advantage is at the cost of necessitating additional space for sto…

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…

Towards Adaptive Memory-Based Optimization for Enhanced Retrieval-Augmented Generation

ACL 2025finding

Retrieval-Augmented Generation (RAG), by integrating non-parametric knowledge from external knowledge bases into models, has emerged as a promising approach to enhancing response accuracy while mitigating factual errors and hallucinations. This method has been widely applied in tasks such as Questio…
