Table 1.
Time taken for 1000 iterations of the gradient descent phase of 2D t-SNE using Barnes-Hut t-SNE (BH t-SNE) compared to our implementation (FIt-SNE), as compared on a 2017 Macbook Pro for a given number of points N. See section 8.3.5 for more details.
N | BH t-SNE | FIt-SNE |
---|---|---|
10,000 | 1 min. | < 1 min. |
100,000 | 11 min. | < 1 min. |
500,000 | 1 hr. 10 min. | 3 min. |
1,000,000 | 3 hr. 9 min. | 15 min. |
