Graph Convolutional Networks (gcns)
overall review score: 4.2
⭐⭐⭐⭐⭐
score is between 0 and 5
Graph Convolutional Networks (GCNs) are a type of deep learning architecture designed to operate directly on graph-structured data. They extend the concept of convolutional neural networks from grid-like data such as images to irregular structures, enabling models to learn features that capture the relational and structural information inherent in graphs. GCNs are widely used in applications including social network analysis, recommendation systems, biological network modeling, and knowledge graph embeddings.
