A Hyperparametrization Is All You Need - Building a Recommendation System for Telecommunication Packages Using Graph Neural Networks

The blog post by Andi Skrgat explores the application of graph neural networks (GNNs) in building a recommendation system for telecommunication packages, emphasizing the effectiveness of GNNs in capturing complex relationships within data. It details how GNNs, part of geometric deep learning, are superior to convolutional neural networks for graph-based tasks due to their ability to aggregate and represent node information from local neighborhoods. The article introduces key models like GraphSAGE and Graph Attention Network (GAT) and discusses their implementation using the DGL library, which supports various backends like PyTorch and TensorFlow. A practical example is provided using IBM's dataset to recommend packages by connecting customer nodes based on shared attributes such as age and location, enhancing the learning process. The post also covers the importance of link prediction, using models like DotPredictor and MLPPredictor, and outlines the training procedure, including hyperparameter tuning. Finally, the blog highlights the results, noting a 90% accuracy and the importance of hyperparameterization, while inviting readers to engage with the Memgraph community for further discussions or contributions.
