Extensive assessment of Barnes-Hut t-SNE.

Year: 2018
Type: conference-paper
Abstract: Stochastic Neighbor Embedding (SNE) and variants are dimensionality reduction (DR) methods able to foil the curse of dimensionality to deliver outstanding experimental results. Mitigating the crowding problem, t-SNE became an extremely popular DR scheme. Its quadratic time complexity in the number of samples is nevertheless unaffordable for big data sets. This motivates its Barnes-Hut (BH) acceleration for large-scale use. Although the latter is faster by orders of magnitude, few studies quantify its DR quality with respect to t-SNE. Extensive comparisons between t-SNE and its BH version are conducted using neighborhood preservation-based criteria. Both methods perform very similarly, suggesting the BH scheme superiority thanks to its reduced time complexity.
