Whats New It proposes a simple and effective way for modeling relations as translation of head to tail using low dimensional embeddings.
How It Works
-
It minimize following margin baed loss:
- d is disimilarity measure, and h', t' are corrupt triplets. corrupt entries are created as below:
-
It experimented on two databases, Freebase and Wordnet.
-
Evaluation criteria:
- It removes head, and instead evaluate disimilarity between h'+l, and t for all entities as h'.
- Arrange all entities h' as per score
- It measures the rank of correct entitiy h = h'
- It also tracks hits @ top-10
-
Results shows that TransE has outperformed current SOTA techniques.
-
Also, perforamnce across 1-1, 1-Many, Many-1, and Many-Many was also encouraging.
-
Few examples of the tail entities predicted are,
-
It also demonstrated capability of transfer learning, by splitting the data into two parts (keeping entities covered, but relationships are partinitoned). TransE was better among the candidates.
