Tips for visualizing with t-SNE
If you have problems getting any results from t-SNE (typically getting the 't-SNE ball'), there are some tricks you can try. Observe that this is not a specific problem with t-SNE, but rather a standard problem in the Machine Learning area.
I need to update the tsne/umap script to an python version because of performance. Nodejs is nice but data science should be done in python, like I did for the https://github.com/cpietsch/smb-vis project
