Suppose we are doing ordinary least-squares linear regression with a fictitious dimension. Which of thefollowing changes can never make the cost function’s value on the training data smaller? A: Discard the fictitious dimension (i.e., don’t append a 1 to every sample point). B: Append quadratic features to each sample point. C: Project the sample points onto a lower-dimensional subspace with PCA (without changing the labels) andperform regression on the projected points. D: Center the design matrix (so each feature has mean zero).

The coefficient matrix is not strictly diagonally dominant, nor can the equations be rearranged to make it so. However, both the Jacobi and the Gauss-Seidel method converge anyway. Demonstrate that this is true of the Gauss-Seidel method, starting with the zero vector as the initial approximation and obtaining a solution that is accurate to within 0.01.
