Graph Representation in Graph Theory - Explore different methods of graph representation including adjacency matrix, adjacency list, and edge list. Learn how these representations are used in graph theory.
In subject area: Computer Science Graph representation learning refers to the process of finding meaningful representations of nodes in a graph by capturing the complex relationships within the graph. These representations, also known as embeddings, are typically low-dimensional and are learned in a da...
In subject area: Computer Science Graph Representation is defined as the way of representing a graph using a compressed adjacency list format. In this format, the vertices of the graph are stored in an array and the edges of all vertices are packed into another array. The weights of the edg...

For a set of n nodes, GSP needs to computer n2 pairwise similarities for both the teacher and student features. We often need to sub-sample large graphs or 3D point clouds when computing LGSP due to GPU memory constraints instead of storing all possible pairwise similarities. For each ...
Graph traversal is widely used in map routing, social network analysis, causal discovery and many more applications. Because it is a memory-bound process, graph traversal puts significant pressure on the memory subsystem. Due to poor spatial locality and the increasing size of today's datasets, ...
In this section, we mainly introduce text-based PTMs since the fantastic Transformer-based PTMs for representation learning begin from NLP, leaving the introduction of the PTMs for graph in Chap.6, multi-modality in Chap.7, and knowledge in Chaps.9,10,11, and12. In the rest of this ch...
The proficiency of graph convolutional networks in learning intricate systems has prompted some researchers to develop representation learning techniques based on this approach. Cui et al.13 introduced DyGCN, a variant of GCN that caters to dynamic networks by updating node embeddings to propagate ...
