ST-CFSFDP:快速搜索密度峰值的时空聚类算法
地理时空大数据挖掘 CFSFDP算法 ST-CFSFDP算法 时空聚类算法
2019/11/25
时空聚类算法是地理时空大数据挖掘的基础研究命题。针对传统CFSFDP聚类算法无法应用于时空数据挖掘的问题,本文提出一种时空约束的ST-CFSFDP(spatial-temporal clustering by fast search and find of density peaks)算法。在CFSFDP算法基础上加入时间约束,修改了样本属性值的计算策略,不仅解决了原算法单簇集多密度峰值问题,且可...
为深入研究煤矿井下串联故障电弧特征及提取方法,分别以电动机和变频器负载为研究对象,开展不同电流条件下的串联型故障电弧实验。采用S变换(ST)对回路电流进行时频域变换,求得S变换矩阵的幅值矩阵作为特征矩阵;对特征矩阵进行奇异分解(SVD),得到矩阵的奇异值;对多组奇异值组成的特征向量进行主元分析(PCA),选取累积贡献率高于95%的主元作为故障识别的特征,实现特征向量的降维;最后采用遗传算法(GA)...
