Suppose that daily temperature has a roughly linear relationship with humidity, cloud cover, and historical temperature. We have the following two data points, each describing a different day:   Humidity    Cloud Cover Hist. Temp Today Temp 10 50 60 60.25 16 20 62 63.3   In the second part of this problem, you will formulate a linear program to determine the best weights , , and to use to predict today’s temperature from the features humidity, cloud cover, and historical temperature. In this problem, the best weights are those that minimize the total absolute prediction error.
