| Challenge: | Existing knowledge graph embeddings have problems expressing knowledge graphs because they model a specific relation r from a head h to tails by transitioning deterministically to exactly one other point in the embeddable space. |
| Approach: | They propose a framework that models relations between nodes by relation-specific, stochastic transitions. |
| Outcome: | The proposed framework is expressive and generic subsuming state-of-the-art models operating on low-dimensional manifolds. |
