I am a Research Engineer in Statistical Learning. After a PhD in Fluid Dynamics and Heat Transfers, I gained a strong interest in maths as a hobby.

comment Multicollinearity and SVD
Thank you very much ! That works very well, I am also able to detect quasi-multicollinearity, which was the reason to use SVD in the first place.

comment Homology group of S1
I think I was mistakenly looking after a single equivalence class with several elements rather than several equivalence classes with a single element.

comment Homotopy groups of a covering space
Searching for the notions you mentioned, I found out there is a whole chapter in "Algebraic Topology" by Hatcher with very visual examples. I guess the most relevant relative to this discussion would be the chapter on deck transformations.
