DisasterRoute: Evidence-Guided Dual-System Routing for Visual Disaster Question Answering

Read the original on arXiv Computer Vision →

DisasterRoute introduces a dual-system routing framework for visual disaster question answering that balances fast direct decisions with selective step-by-step reasoning. The system first uses Disaster-S1, a vision‑language model trained for option discrimination, to produce a quick answer. If the model’s confidence is low or evidence suggests uncertainty, the framework routes the query to DisasterVL, a more comprehensive reasoning model, thereby improving accuracy while maintaining low latency.

DisasterBench: A Multimodal Benchmark for UAV-Based Disaster Response in Complex Environments

arXiv:2606. 06217v1 Announce Type: cross Abstract: When a disaster unfolds, responders must answer not only what is happening, but also why it is happening, what will happen next, and what to do now, often from noisy low-altitude UAV views and under tight on-site compute constraints.

LADBench: A Benchmark for Logical Fault Detection in Images

LADBench is a new benchmark comprising over 1,000 synthetic images that contain logical anomalies across four domains—Residential, Urban, Collaborative, and Nature. It introduces a Tiered Prompting Protocol that progressively discloses information to test how much explicit help a model needs to locate and reason about these faults. Evaluation of leading foundation models shows that even the best only reaches 70.11% accuracy, indicating that implicit logical fault detection remains largely unsolved.
