谱聚类(spectral clustering)是广泛使用的聚类算法,比起传统的K-Means算法,谱聚类对数据分布的适应性更强,聚类效果也很优秀,同时聚类的计算量也小很多,更加难能可贵的是实现起来也不复杂。在处理实际的聚类问题时,个人认为谱聚类是应该首先考虑的几种算法之一。下面我们就对谱聚类的算法原理做一个总结。 1. 谱聚类...
We then propose a centralized cluster algorithm based on spectral partitioning method. After that, we present a distributed implementation of the clustering algorithm based on fuzzy C-means method. Finally, we conduct extensive simulations, and the results show that the proposed algorithms outperform ...

which is prone to cause wrong recognition. To solve the above problems, an improved FCM algorithm is proposed in this paper for Terahertz spectral recognition. Firstly, t-SNE method is used for dimensional reduction and for the selection of initial clustering center for a more accurate clustering...
