This paper introduced an outlier detection algorithm based on the shared nearest neighbor clustering in order to detect the outliers with the mixed attributes. The algorithm calculated the shared nearest neighbor similarity measure between result clusters caused by the incremental clustering. It could not...
Finally, the experimental and comparative evaluation of several datasets from diverse domains established the viability of the DPC-SNNACC algorithm. 展开 关键词: clustering by fast search and find density peaks shared-nearest neighbor adaptive clustering center knee point clustering by fast search and ...
complete data structure information, so proposes the adaptive spectral clustering based on shared natural nearest neighborhood, in which each point's neighbors are formed by an adaptive algorithm without parameter, at the same time, similarity combining the concept of shared nearest neighbors will ...
1)Nearest NeighborCondition 最近邻条件: 这个条件的意思是编码区域Sn应该包含所有与cn最接近的矢量(相比于与其他码矢的距离)。对于在边界(蓝色线)上面的矢量,需要采用一些决策方法(any tie-breaking procedure)。 2)Centroid Condition质心条件: 这个条件要求码矢cn是编码区域Sn内所有的训练样本向量的平均向量。在实现...
In the second phase, the disjoint features are added to the feature set (S1) by following steps 7 to 36 of Algorithm 1. For this, the value of shared nearest neighbors (N) is calculated according to Equation (7). 𝑁=|𝑉||𝑆|N=|V||S| (7) Further, the ‘k’ parameter ...
