Module 6 - MA1 1. . Q2 Q1 9= Question 1 Suppose that we are given a data set of 20 points in 2d space. When the first principal component of the data set is computed, the result is as follows: 1 X u:(fi’fi) If we add one data point to the data set at (2,2), how would this first principle component change? It would rotate toward the x axis. o It would not. It would rotate toward the y axis. 9~ Question 2 Suppose that we are given a data set of 20 points in 2d space. When the first principal component of the data set is computed, the result is as follows: 1 1 u=(—=,—x) V2 V2 If we add an extremely large number of data points which are uniformly distributed on the y-axis from 0 to -10, how would this change the principle component? It would become (-1, 0). It would become (1, 0) It would become (1, 1) o It would become (0, -1) CSE 575 Page 1
