【摘要】:根據數(shù)據挖掘技術分析列車運行大數(shù)據的特點,提出了基于屬性矩陣圖的決策樹算法。結合某列車仿真數(shù)據,詳細闡述了計算屬性度量、構建屬性矩陣圖模型及構造決策樹的具體過程。由該決策樹算法的故障分析結果可見,基于屬性矩陣圖決策樹算法能準確地對故障問題進行分類歸納,為故障預測提供可靠依據。
[Abstract]:According to the characteristics of train running big data, a decision tree algorithm based on attribute matrix graph is proposed. Based on the simulation data of a certain train, the concrete process of calculating attribute metric, building attribute matrix graph model and constructing decision tree is described in detail. From the fault analysis results of the decision tree algorithm, it can be seen that the decision tree algorithm based on attribute matrix graph can accurately classify and induce fault problems, and provide reliable basis for fault prediction.
