In this assignment, you will fit linear regression models and implement a few simple feature variable selection algorithms. We then initialize Linear Regression to a variable reg. Therefore, the complexity of our Bayesian linear regression, which has a lower bound complexity of $\mathcal{O}(n^3)$, is going to be a limiting factor for scaling to large datasets. One of the main point of this example is the importance of taking into account outliers in the test dataset when dealing with real datasets. Various transformations are used in the table on pages 244-261 of the latter. Similar to classification, in this section, we will train and visualize a model for regression.
