| Nov 16, 2021 at 22:53 | comment | added | Andrei Smolensky | @ZachTeitler Images under arbitrary linear maps is not a priori the same as images under scaling in orthogonal directions and rotations. They are, but this is precisely the SVD. | |
| Nov 16, 2021 at 22:08 | comment | added | Zach Teitler | I'm not sure how deep it is to say that linear maps take linear images of spheres to linear images of spheres. Perhaps I'm missing something. | |
| Nov 16, 2021 at 16:51 | comment | added | wlad | @ZachTeitler It's the result of taking a sphere and stretching it in orthogonal directions. Does that clarify? | |
| Nov 16, 2021 at 15:55 | comment | added | Zach Teitler | Please forgive a stupid question, but what is the definition of an ellipse here? A compact level set of a quadratic polynomial? But I think that's equivalent to being a linear image of a sphere, no? Perhaps something else is intended. | |
