快速搜索密度峰值的时空聚类(spatial-temporal clustering by fast search and find of density peaks, ST-CFSFDP)算法在处理时空数据时未充分考虑样本间密度差异,导致样本的局部密度不能正确反映样本的密度分布;通过欧氏距离计算样本的相对距离,无法将时间邻近的簇进行区分。针对以上问题,提出相对密度和马氏距离的时空密度峰值聚类(spatial-temporal density peaks clustering algorithm with relative density and mahalanobis distance, ST-DPC-RDMD)算法。ST-DPC-RDMD算法在局部密度中引入时空近邻概念,并结合相对密度思想重新定义样本局部密度,提高近邻样本的影响程度;使用空间与时间属性的马氏距离替代欧氏距离,综合分析各维度的协方差关系实现空间与时间距离权重的合理分配,以准确识别具有特征差异的簇。在模拟数据集和真实地震数据集上的实验结果表明,ST-DPC-RDMD算法的聚类效果优势显著。
- Abstract:
-
The spatial-temporal clustering by fast search and find of density peaks (ST-CFSFDP) fails to fully consider density differences among samples when processing spatial-temporal data, resulting in the inability of sample local density to accurately reflect density distribution. Additionally, using Euclidean distance to calculate relative distances between samples prevents the differentiation of clusters that are temporally adjacent but spatially distinct. To address these issues, a spatial-temporal density peaks clustering algorithm with relative density and Mahalanobis distance (ST-DPC-RDMD) is proposed. The ST-DPC-RDMD algorithm introduces the concept of spatial-temporal nearest neighbors into local density and redefines sample local density by incorporating the idea of relative density, thereby enhancing the influence of neighboring samples, amplifying the local density of samples in sparse clusters, and reducing the impact of inter-cluster density heterogeneity. It replaces Euclidean distance with Mahalanobis distance for spatial and temporal attributes, comprehensively analyzing covariance relationships across various dimensions to achieve a reasonable allocation of weights between spatial and temporal distances, thus accurately identifying clusters with characteristic differences. Experimental results on simulated datasets and real earthquake datasets demonstrate that the ST-DPC-RDMD algorithm exhibits significant advantages in clustering performance.
