The main steps are as follows:Firstly,by taking advantages of non-parametric density estimation,possibility density function(PDF) is determined,which is taken as the index of clustering,where areas with larger value of PDF would be taken as clustering prototypes;Secondly,the gradient field of PDF is estimated by means of non-parametric estimation;Thirdly,the prototypes o.
该方法实现如下:①利用非参数密度估计方法估计样本空间概率密度函数,并以概率密度函数作为聚类依据,密度函数值较大的区域将有可能作为类簇原型区;②利用非参数估计方法直接估计出概率密度函数的梯度场;③依据概率密度函数的梯度分布确定聚类原型,进而利用峡谷搜索法思想建立聚类划分;④最后利用类簇划分的边界确定变压器故障的区分边界。
