动态时间弯曲(DTW)距离是时间序列相似搜索的一种重要距离度量,但其精确计算是一个性能瓶颈。
Dynamic time Warping (DTW) is one of the important distance measures in similarity searching of time series; however, the exact calculation has become a bottleneck.
对某大型液体火箭发动机的热试车数据及通过发动机模型仿真得到的故障数据进行动态时间弯曲分析,得到弯曲路径集,然后结合决策树方法进行了故障检测和诊断。
Through dynamic time warping analysis to the hot-fire test data and simulated fault data of a certain liquid rocket engine, the warped path sets were obtained.
