Unlocking Vision-Language Models for Video Anomaly Detection via Fine-Grained Prompting

Shu Zou, Xinyu Tian, Lukas Wesemann +3

Prompting has emerged as a practical way to adapt frozen vision-language models (VLMs) for video anomaly detection (VAD). Yet, existing prompts are often overly abstract, overlooki…

More Thought, Less Accuracy? On the Dual Nature of Reasoning in Vision-Language Models

Xinyu Tian, Shu Zou, Zhaoyuan Yang +5

Reasoning has emerged as a pivotal capability in Large Language Models (LLMs). Through Reinforcement Learning (RL), typically Group Relative Policy Optimization (GRPO), these model…

Robust Spatiotemporal Forecasting Using Adaptive Deep-Unfolded Variational Mode Decomposition

Osama Ahmad, Lukas Wesemann, Fabian Waschkowski +1

Accurate spatiotemporal forecasting is critical for numerous complex systems but remains challenging due to complex volatility patterns and spectral entanglement in conventional gr…
