WebThese observations indicate that the fully-connected structure for self-attention operations can be replaced by a more sparse one where only specific edges are constructed for attention operations. The adjacency matrix may be used as a data structure for the representation of graphs in computer programs for manipulating graphs. The main alternative data structure, also in use for this application, is the adjacency list. The space needed to represent an adjacency matrix and the time needed to perform operations on them is dependent on the matrix representation chosen for the underlying matrix. Sparse matri…

Web18 mei 2016 · If your graph is sparse, you may want to use the vertex ordering version of the algorithm: For sparse graphs, tighter bounds are possible. In particular the vertex-ordering version of the Bron–Kerbosch algorithm can be made to run in time O (dn3d/3), where d is the degeneracy of the graph, a measure of its sparseness.

Webfully connected graphs (Mihalcea and Tarau 2004; Zheng and Lapata 2024; Wang et al. 2024), we induce sparse graphs by selecting a subset of nodes as neighbors for a scene; the size of this subset is not set in advance but learnt as part of the network.
