Simplicial method

WebbThe term’ simplicial decomposition’ is due to B. von Hohenbalken [ 22 ], but the essential idea is generally known as column generation and has been called inner linearization/restriction by A.M. Geoffrion [ 7 ]. In general, SD addresses the following problem (1) where f ( x) is pseudoconvex. Webb为了更好地学习网络中的高阶信息和异质信息，基于单纯复形提出单纯复形—异质图注意力神经网络方法—SC-HGANN。. 首先，用单纯复形提取网络高阶结构，将单纯复形转换为单纯复形矩阵；其次，使用注意力机制从特征单纯复形中得到异质节点的特征；再次，对 ...
