WebIn this paper, we propose a novel topological pre-training paradigm MGTLM to enjoy the merits of behavior graphs while avoiding explicit topological operations. MGTLM is capable of teaching language models to understand multi-grained topological information, which contributes to eliminating explicit graph aggregations and avoiding information loss. WebIn topological graph theory, an embedding (also spelled imbedding) of a graph on a surface is a representation of on in which points of are associated with vertices and simple arcs (homeomorphic images of [,]) are associated with edges in such a way that: . the endpoints of the arc associated with an edge are the points associated with the end … WebNov 18, 2024 · Graph Neural Networks can be considered as a special case of the Geometric Deep Learning Blueprint, whose building blocks are a domain with a symmetry group (graph with the permutation group in this case), signals on the domain (node features), and group-equivariant functions on such signals (message passing)..

"In mathematics, topological graph theory is a branch of graph theory. It studies the embedding of graphs in surfaces, spatial embeddings of graphs, and graphs as topological spaces. It also studies immersions of graphs. Embedding a graph in a surface means that we want to draw the graph on a surface, a sphere for example, without two edges intersecting. A basic embedding problem often presented as a mathe… " - Graph topological

If you greedily revisit all neighbours which you can improve the longest distance. For example at 9, you can just check that 9+1 > 7 and revisit the 7th node to update it. BUT just to clarify, the big O gets worse.
