Preeti … NettetThis tutorial will teach you how to train a GNN for link prediction, i.e. predicting the existence of an edge between two arbitrary nodes in a graph. By the end of this tutorial you will be able to Build a GNN-based link prediction model. Train and evaluate the model on a small DGL-provided dataset. (Time estimate: 28 minutes)

Nettet3. jun. 2024 · Learning to predict missing links is important for many graph-based applications. Existing methods were designed to learn the association between observed graph structure and existence of link between a pair of nodes. However, the causal relationship between the two variables was largely ignored for learning to predict links … Nettet15. apr. 2024 · We introduce a novel embedding model, named NoGE, which aims to integrate co-occurrence among entities and relations into graph neural networks to improve knowledge graph completion (i.e., link prediction). Given a knowledge graph, NoGE constructs a single graph considering entities and relations as individual nodes. …
