Hypergraph random walk
Web随机游走（random walk）是图论中的重要算法，在数据挖掘领域有广泛的应用。 简而言之，随机游走算法构建了若干个随机游走器（random walker）。 随机游走器从某个节点初始化，之后在每一步随机游走中，随机地访问当前节点的某个邻接节点。 随机游走一项有名的应用即为谷歌的PageRank算法，如图 2所示。 PageRank算法中，每个随机游走器均模 … Web随机游走标准化 (random walk Laplacian) L_ {RW} = D^ {-1} L 这些变体也享有拉普拉斯矩阵的三个特性，但此前关于特征值为0的节点连接结论则要随着特征值的标准化的改变而改变。 2. 图割法与聚类（Graph cuts and clustering） 此前关于Laplacian特征值为0进而发现连接节点的结论比较特殊，毕竟要求Laplacian矩阵存在彼此不相关的多个子块，这一节主 …
