摘要: 文中从实际工程需要出发,结合随机采样一致性原理,将每一个数据点描述为适合该点首选的假定模型的倾向集集合,再基于倾向集之间的Jaccard距离,采用一种经过改良的密集聚类方法,聚集属于同一种模型的数据点.这种方法既不要求事先指定模型数目,也不需要进行参数调试.实验表明,该算法检测效果明显,精确度较高.Abstract: Start from the actual needs of engineering,each data point is represented with a preference set of hypotheses models preferred by that point in this paper.Subsequently,based on random sample consensus principle,a improved agglomerative clustering should be adopted to collect those points which fall into a same model.The method does not require prior specification of the number of models,nor it necessitate parameters tuning.Experimental results demonstrate the obvious effect and greater accuracy of the algorithm.
