Abstract • 问题：对于嵌入在高维空间的低维流形数据的表示； • 利用图Laplacian算子、流形上的 Laplacian Beltrami 算子和热方程的对应关系； • 局部保留能力和与聚类的自然联系。 1 Introduction • 传统降维方法如PCA、MDS，非线性映射方法如自组织映射和其它基于神经网络的方法，Minimum Height Trees 解答
Question For an undirected graph with tree characteristics, we can choose any node as the root. The result graph is then a rooted tree. Among all possible rooted trees, those with minimum height are called minimum height trees (MHTs). Given such a graph,
