Like mentioned in another answer, it should convert an Array of vectors into another Array of different vectors. The vectors represent a 3d model and so the general shape of the model should stay the same, just represent through less vectors.

Can you explain how I should phrase my problem more precisely? What information would you need in order to understand it better? In an abstract way my example explains precisely what it should do. If you change the numbers with vectors you have the exact case.

And so I also googled professionally beforehand and thought I'd also get the opinion of the pros without bias.

I will take a look at autocorrect, thank you :)
What I thought would be best are diffusion models, since denoising, etc. seems like the same concept.
