| - | In what follows set aside 30% of the data as a test-set, and compute the in-sample error, and the test-set error as a function of the parameter $\lambda$ on the red wine data. Choose the values of $\lambda$ on a logarithmic scale with values 0.01, 0.1, 1, 10, 100, 1000 and plot the RMSE only. | + | In what follows set aside 30% of the data as a validation-set, and compute the in-sample error, and the validation-set error as a function of the parameter $\lambda$ on the red wine data.
