a) Find the optimal linear regression model manually by following slides

a) Find the optimal linear regression model manually by following slides 5 and 6 . Show the squared test error. Draw your optimal function and dataset in a diagram. b) Find the optimal quadratic regression model. Show the squared error. Draw your optimal function and dataset in diagram. c) Compare the errors in the above two models and discuss the impact of capacity. d) Assume linear regression model and an initialized model parameter =(0.800.60)T. Suppose learning rate =0.001. Calculate one step update for the parameter using backward error propagation as in slide 9 of chapter 2 and summed square error
