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 ... Webb22 nov. 2024 · Here, we extend spectral methods for feature selection to abstract simplicial complexes and present a general framework for clustering-independent analysis. Combinatorial Laplacian scores take into account the topology spanned by the data and reduce to the ordinary Laplacian score when restricted to graphs.
Webb13 sep. 2016 · This paper reports some new results in relation to simplicial algorithms considering continuities of approximate fixed point sets. The upper semi-continuity of a set-valued mapping of approximate fixed points using vector-valued simplicial methods is proved, and thus one obtains the existence of finite essential connected components in … WebbEugene Allgower, Kurt Georg, Simplicial and continuation methods for approximating fixed points and solutions to systems of equations, SIAM Rev., 22 (1980), 28–85 Crossref ISI
WebbThe author gives a Yoneda-type interpretation of triple cohomology in a nonabelian setting.
