HD-CLIP: Hierarchical Dynamic Prompting and Decoupled Learning for Zero-Shot Anomaly Detection

The potential of vision-language models (VLMs) such as CLIP for zero-shot anomaly detection (ZSAD) is constrained by an inherent semantic-localization dichotomy. While CLIP’s global features excel at image-level classification, they lack the spatial sensitivity required for pixel-level segmentation. Existing approaches...

Learning from Unreachable Rewards: Hint-Conditioned Reinforcement Learning for Generative Recommendation

This work proposes Hint-Conditioned Generative Recommendation (HCGRec), a semantic-ID generative recommendation framework that recovers learning signal for such hard training instances and introduces hint-aware credit decomposition, using supervised learning to preserve item-semantic and prefix-structure alignment for...
