Hi,

In 2013MoedB, very last section, we are given the points (2,0),(1,0),(0,2),(0,1),(0,0),

And the question is "what is the line defined by the dimension reduction using PCA"?

What does that actually mean ? Do we have to compute the re-projected points by computing $UU^{t}x$ and then compute the regression line ? (where U is the PCA matrix)

Thanks
