Q10. Given X e Rnxd, y ER, consider the linear regression

Q10. Given X e Rnxd, y ER, consider the linear regression problem: min lly - Xw1|2. WER What is the time complexity (in big O notation) to obtain the closed-form solution of w? (Suppose the time complexity of calculating the pseudo inverse of a matrix of dimension n x n is O(n)). (a) O(n). (b) O(n3 + d-n). (c) O(n + nad). (d) Old + d ). (e) O(n3 + d)
