Description: A Graph Neural Network (GNN) is a type of neural network designed to operate on graph structures, making it particularly useful for tasks involving relational data. Unlike traditional neural networks, which typically work with data in the form of vectors or matrices, GNNs can process information organized into nodes and edges, allowing them to capture complex relationships between entities. This is especially relevant in fields like social network analysis, recommendation systems, and biological data analysis, where data can be represented as graphs, with entities as nodes and relationships as edges. GNNs utilize message-passing techniques, where information is exchanged between neighboring nodes, enabling the network to learn meaningful representations of the graph structure. This ability to model nonlinear relationships and spatial dependencies makes them a powerful tool for tasks such as classification, regression, and clustering, where understanding the relationship between different parts of a dataset is crucial for achieving accurate results.
