DOWSER: A DINO-based One-shot Water Seepage Recognition network for TBM tunnel inspection

Zehao Ye, Neng Wang, Huamei Zhu, Qian Zhang, Zili Li, Jelena Ninić

The industrial deployment of supervised models for tunnel damage detection is limited by the high cost of data collection and pixel-level annotation. Although deep learning has advanced defect detection, its heavy data requirements remain impractical for dynamic construction envi…

Self-Reference in Large Language Models: The Introspection Threshold for Recursive Self-Improvement

Jiang Zhang, Bing Yuan, Qian Zhang

The pursuit of self-evolving AI raises a critical question: when is autonomous self-improvement sustainable rather than degenerative? Drawing an analogy to von Neumann's complexity threshold for self-reproducing automata, we argue that sustainable recursive self-improvement in La…

Revealing Safety-Critical Scenarios for UTM via Transformer

Huaze Tang, Bill Zeng, Chao Wang, Zhenpeng Shi, Qian Zhang, Wenbo Ding

Unmanned Traffic Management (UTM) systems are cloud-based platforms designed to manage and coordinate multiple aerial vehicles remotely. UTM systems are safety-critical which cannot tolerate failures like crash or collision. To reveal latent vulnerabilities, there are neither opt…

SPACE: Swarm Pheromone Fields for Adaptive Collision-Aware Exploration

Haohua Que, Haojia Gao, Mingkai Liu, Qian Zhang, Jiajun Sun, Fei Qiao

Massive robot swarms can explore unknown environments quickly, but adding robots eventually stops helping. Doorways and dense traffic create congestion, increasing inter-robot contacts and reducing the value of each additional robot. We study this safety-efficiency tradeoff for g…
