BH t-SNE Demo
# coding: utf-8
### Summary
# This notebook presents the Barnes-Hut implementation of t-SNE. t-SNE is used to visualize high-dimensional data in a low dimensional space that attempts preserve the pairwise high-dimensional similarities in a low-dimensional embedding. The Barnes-Hut algorithm, which is used by astrophysicists to perform N-body simulations, allows the calculation of the t-SNE embedding in $O(N log N)$ time instead of $O(N^{2})$. This effectively allows us to learn embeddings of data sets with millions of elements instead of tens of thousands.
### Install
# To try out out the BH version of t-SNE, do the following:
