Graph Neural Networks for Practical AI Systems: Designing Architectures and Training Pipelines for Scalable Graph Intelligence with GCN, GAT, GraphSAGE, and PyTorch Geometric

Graph Neural Networks (GNNs) are transforming the way AI systems reason about complex, relational data. In domains like social networks, recommendation engines, knowledge graphs, fraud detection, and beyond, the relationships between entities are often more important than the entities themselves. Traditional deep learning approaches struggle to capture these intricate connections, leaving a gap in both performance and interpretability. Graph Neural Networks for Practical AI Systems is a comprehensive, hands-on guide that ... Read More
