Regression III

Week 04, Fall 2023


This week we will continue discussing the supervised learning regression task, but more through the lense of theory. In particular, we’ll discussion the bias-variance tradeoff and how model flexibility relates to overfitting.

Learning Objectives

After completing this week, you are expected to be able to:

  • Understand how model flexibility relates to the bias-variance tradeoff and thus model performance.
  • Select models by manipulating their flexibility through the use of a tuning parameter.
  • Avoid overfitting by selecting an a model of appropriate flexibility through the use of a validation set.
