| Visualizing the action of a neural answer retrieval system. The blue point at the north pole represents the question vector. The other points represent the embeddings of various answers. The correct answer, highlighted here in red, is “closest” to the question, in that it minimizes the angular distance. The points in this diagram are produced by an actual USE-QA model, however, they have been projected downwards from ℝ500 to ℝ3 to assist the reader’s visualization. |
