What’s a graph embedding, and how does it factor into knowledge engineering?
^^
A graph embedding is a technique used to convert nodes, edges, or entire subgraphs in a graph into continuous vectors or low-dimensional representations that can be more easily processed by machine learning algorithms. The goal of graph embeddings is to capture the structure, relationships, and properties of a graph in a compact, continuous form while preserving important information about the graph.
^^
Graph embeddings are particularly useful in the context of knowledge engineering because they can help convert the structured information in knowledge graphs into a format that can be more easily integrated with machine learning algorithms, especially neural networks. This enables machine learning models to leverage the rich information encoded in knowledge graphs for various tasks, such as node classification, link prediction, and recommendation systems.
