Question

Given 6 data points in 5-d space, (1, 1, 1, 0, 0), (3, 3, 3, 0, 0), (2, 2, 2, 0, 0), (0, 0, 0, 1, 1), (0, 0, 0, 2, 2), (0, 0, 0, 1, 1). We can represent these data points by a 6 5 matrix x, where each row corresponds to a data point. (a) what is svd of the data matrix x you choose? (b) what is first principle component for the original data points?

Answer 1

I choose data matrix (1,1,1,0,0)
