Graph Convolutional Networks (GCNs): Architectural Insights and ...
2024年6月21日 · Graph Convolutional Networks (GCNs) are a type of neural network designed to work directly with graphs. A graph consists of nodes (vertices) and edges (connections between nodes). In a GCN, each node represents an entity, and the edges represent the relationships between these entities.
Graph Convolutional Networks | Thomas Kipf | Google …
2016年9月30日 · Currently, most graph neural network models have a somewhat universal architecture in common. I will refer to these models as Graph Convolutional Networks (GCNs); convolutional, because filter parameters are typically shared over all locations in the graph (or a subset thereof as in Duvenaud et al., NIPS 2015).

Graph Convolution - an overview | ScienceDirect Topics
'Graph Convolution' refers to the operation in graph convolutional networks where feature representations of nodes and graphs are learned by passing messages through the edges of a graph, similar to how convolutional neural networks consider the spatial structure of grid structured data.
Graph Convolutional Network - an overview - ScienceDirect
In summary, GCNs offer a promising approach for trajectory prediction by explicitly modelling the spatial dependencies and relationships among objects. They can effectively capture contextual information and handle irregular graph structures.
[2206.10991] Understanding convolution on graphs via energies
2022年6月22日 · Most message-passing models act as graph convolutions, where features are mixed by a shared, linear transformation before being propagated over the edges. On node-classification tasks, graph convolutions have been shown to suffer from two limitations: poor performance on heterophilic graphs, and over-smoothing.
