Technical meaning of axes

I’d love to understand on a technical level what the three axes of the visualizer represent. I get what they mean on an intuitive level, and obviously one can’t cleanly visualize more than 3D. Perhaps EI selects the top three most varying features and uses those to approximate overall separation?

My lack of knowledge in ML theory is showing :grimacing: Please educate me!

Exactly what I was after. Thank you.
