Hey folks, AI-related video 😃 Sorry. The reason I'm thinking about the geometry of this is because I'm hoping it might lead to UI ideas, hence posting here.

Gradient descent on the mouse-food example produces curves that resemble those in the video, at least visually. What makes those curves less than ideal?

Maybe it’s just a situation where the natural and vanilla gradient descent solutions coincide? All I know about the natural variation I learned from your video. I’m curious to learn more!

I've read enough now to understand that, although the shapes look roughly similar for this problem, vanilla gradient descent makes large steps in the belief space, which I can see if I plot KL divergence of each successive optimization step.

Anyway, I loved the video. I'd much rather watch a ten minute video that makes me think for an hour than an hour-long video that I think about for ten minutes. 🙂

That's a very nice explanation of non-euclidian spaces!
