Tiny but Trusted: Efficient Vision-Language Reasoning for Time-Series Anomaly Detection

ArXi:2605.30344v1 Announce Type: new Recent advances in Vision-Language Models (VLMs) have achieved impressive performance across many tasks, yet prior studies report unsatisfactory performance when applying large language or multimodal models to finding abnormal patterns in sequential data. Public anomaly detection benchmarks typically provide interval annotations but not natural-language rationales, making it difficult to fine-tune VLMs to produce grounded, interpretable decisions.
