I like how you are able to take subjects that are very complicated to learn about and teach them in a simple manner at a level I can understand.

I spent some hours taking notes and even reading from wiki when you added it as note so simply I passed through all the topics you added.

I have one question, you said after explaining the total least square regression that we can simply project the data onto the largest eigen vectors. Is that after or before rotation as I can’t find it make sense to do that projection after rotation as I though actually we can just remove any feature based on application.
