Easy to Learn, Yet Hard to Forget: Towards Robust Unlearning Under Bias

This paper introduces CUPID, a novel unlearning framework that addresses the "shortcut unlearning" phenomenon—where models struggle to forget bias-aligned samples by instead unlearning the bias itself—by partitioning data based on loss landscape sharpness and disentangling model parameters to perform targeted updates that effectively mitigate unintended biases.

Beyond Static Artifacts: A Forensic Benchmark for Video Deepfake Reasoning in Vision Language Models

This paper introduces Forensic Answer-Questioning (FAQ), a large-scale benchmark and corresponding instruction-tuning set designed to enhance Vision-Language Models' ability to detect video deepfakes by evaluating and improving their temporal reasoning capabilities across three hierarchical levels: facial perception, temporal grounding, and forensic reasoning.

Meta-FC: Meta-Learning with Feature Consistency for Robust and Generalizable Watermarking

This paper proposes Meta-FC, a novel meta-learning framework that enhances the robustness and generalizability of deep learning-based watermarking by addressing the optimization conflicts of single-random-distortion training through feature consistency constraints and meta-training tasks designed to identify distortion-invariant representations.

Understanding Annotation Error Propagation and Learning an Adaptive Policy for Expert Intervention in Barrett's Video Segmentation

This paper proposes Learning-to-Re-Prompt (L2RP), a cost-aware framework that analyzes annotation error propagation in endoscopic video segmentation and dynamically learns an adaptive policy to optimize the trade-off between expert intervention effort and segmentation accuracy for Barrett's esophagus dysplasia.

Directed Ordinal Diffusion Regularization for Progression-Aware Diabetic Retinopathy Grading

This paper proposes Directed Ordinal Diffusion Regularization (D-ODR), a novel method that enforces the unidirectional nature of diabetic retinopathy progression through a directed graph and multi-scale diffusion, thereby preventing biologically implausible reverse transitions and achieving superior grading performance compared to existing state-of-the-art approaches.
