Hands On Graph Neural Networks Using Python
This repository serves as an educational resource for implementing graph neural networks using Python. It provides a collection of structured code examples and tutorials designed to guide developers through the process of building and training machine learning models that operate on complex, interconnected datasets.
The project covers the core mechanics of graph-based deep learning, including message-passing architectures, feature aggregation, and the stacking of convolutional layers. It demonstrates how to represent non-Euclidean data as static graphs and how to manage memory during training through mini-batch sampling techniques.
The included implementations address common analytical tasks such as node classification, graph structure prediction, and the integration of heterogeneous data sources into unified models. The repository is organized as a series of practical exercises that translate theoretical graph concepts into functional machine learning workflows.
