摘要:

在这项工作中,聚类相关的随机变量的可能性进行了检查,因为它们的相互相似性,因为它们的相似性的主成分。聚类采用k-means算法和谱算法。对于光谱方法,相似性矩阵既是建立在相关水平上的关系矩阵,也是决定系数矩阵。针对4组不同的数据,分析了不同的变量差异性度量方法,并分析了初始点的差异性对k-means算法效率的影响。

英文摘要:

In this work, the possibility of clustering correlated random variables was examined, both because of their mutual similarity and because of their similarity to the principal components. The k-means algorithm and spectral algorithms were used for clustering. For spectral methods, the similarity matrix was both the matrix of relation established on the level of correlation and the matrix of coefficients of determination. For four different sets of data, different ways of measuring the disimilarity of variables were analyzed, and the impact of the diversity of initial points on the efficiency of the k-means algorithm was analyzed.
