PCD-Net: prior-context collaborative learning for robust facial expression recognition under noisy labels

Noisy annotations and class imbalance commonly coexist in real-world facial expression recognition (FER), making hard but correctly labeled minority-class samples difficult to distinguish from unreliable training samples. Existing noisy FER approaches mainly improve robustness through sample selection or re-weighting...

Reliability-aware vision-language face anti-spoofing via progressive semantic reorganization

Face Anti-Spoofing (FAS) is a crucial task for securing face recognition systems, yet its cross-domain generalization remains challenging. Recently, vision-language methods built upon pretrained models such as CLIP have shown promising performance in addressing these cross-domain scenarios. Nevertheless, existing appro...

Document-level relation extraction via self-correcting prompt optimization and preference alignment

This paper proposes SPO-PA, which combines self-correcting prompt optimization (SPO) and preference alignment (PA), which compares LLM predictions with reference annotations and applies source-specific constraints to these signals.
