Researchers have developed a novel federated approach for video anomaly detection using vision-language models (VLMs). This method addresses challenges of distributed, weakly labeled, and resource-constrained surveillance data by training a lightweight federated MIL scorer across clients and using a frozen VLM for post-hoc verification. Experiments on the UCF-Crime dataset with InternVL3.5-2B and Qwen3-VL-2B-Instruct demonstrated that a logit-based interface provides a parser-free, continuous anomaly signal, improving performance over the baseline MIL scorer without requiring temporal post-processing.
