Railway Side Slope Hazard Detection System Based on Generative Models
Bibliographic record
Abstract
The use of drones for image monitoring has gained popularity in railway operations due to several significant advantages. Drones provide high-resolution aerial imagery that covers vast and hard-to-reach areas, enabling comprehensive monitoring of the entire railway network. They offer flexibility and rapid deployment, allowing for real-time data collection and analysis, which is crucial for early detection of potential risks such as landslides, erosion, or track obstructions. Moreover, drones can operate in challenging weather conditions and difficult terrains, ensuring continuous monitoring where traditional methods might fail. However, data collected from drones for railway side slope monitoring is scarce and the railway side slope defect identification and risk assessment have not been fully studied. Furthermore, its frequency is often limited due to operational safety concerns, leading to insufficient data acquisition. To address these limitations, this study innovatively employs diffusion models augmented by large language models (LLMs) to enhance training datasets with high-quality synthetic images that encapsulate various defect scenarios. The enhanced You Only Look Once (YOLO) system, integrated with attention mechanisms and LLM-augmented diffusion generation, significantly improves detection accuracy by enabling the model to better generalize under varied real-world conditions. In this study, we collected 600 images from hazardous real-world environments and provided a comprehensive evaluation framework, demonstrating superior performance metrics compared to traditional methods. This approach offers a promising solution for automating and enhancing the reliability of geological hazard monitoring along railway side slopes. The source dataset will be open-sourced athttps://github.com/CRH380-CR400/Dataset-of-slope-diseases-along-railway-lines.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
