Heterogeneity‐oriented ensemble learning for rail monitoring based on vehicle‐body vibration
Computer-Aided Civil and Infrastructure Engineering, Volume 39, Issue 12, Page 1766-1794, 15 June 2024.Abstract In this study, railway vehicle‐body vibration was applied to rail detection for convenient sensor deployment and cost‐effectiveness. However, the waveform is difficult to analyze due to damping and interference. Data‐driven methods can help concatenate multidimensional signals and complex rail‐surface irregularities but are impressionably ...
