Our main message is that the popular method of low-dimensional embeddings provably cannot capture important properties of real-world complex networks. A widely used algorithmic technique for modeling ...

Link prediction is a fundamental machine learning task on complex networks, used to evaluate the central technique of low-dimensional embeddings. Our results question the common wisdom that ...
