The closed form solution for least squares is (XX)1Xy. This equations computational complexity scales exponentially_with such that the complexity is approximately O(n3). weights features data samples The closed form solution for least squares is (XX)1Xy. This equations computational complexity scales linearly. with such that the complexity is O(m). weights data samples features Which Linear Regression algorithm would we want to use if we had a training dataset with millions of data samples?
