Summary

tSNEJS tSNEJS is an implementation of t-SNE visualization algorithm in Javascript. t-SNE is a visualization algorithm that embeds things in 2 or 3 dimensions. If you have some data and you can measure their pairwise differences, t-SNE visualization can help you identify clusters in your data. See example below. Online demo The main project website has a $1andmoredescription.Thereisalsothe$1 that allows you to simply paste CSV data into a textbox and tSNEJS computes and visualizes the embedding on the fly (no coding needed). Research Paper The algorithm was originally described in this paper: L.J.P. van de…

What This Teaches

• How ML ideas can be made interactive and inspectable in the browser.
• Useful for teaching interfaces and lightweight demos.

Why It Matters

This matters as part of Karpathy’s broader pattern: compress hard technical systems into readable, inspectable, working artifacts.
