Machine Learning Regularization and Cross-Validation for Econometrics

In this video, we explore two fundamental concepts that every econometrician needs to master when implementing machine learning methods: regularization and cross-validation. These techniques are essential for ensuring your prediction models don't overfit and generalize well to new data. Slides used in the video are available here: https://raw.githack.com/tyleransom/st... Source code of slides is here: https://github.com/tyleransom/structu... Here are the notes mentioned in the video: https://www.cs.princeton.edu/courses/... Key Topics Covered: Cross-Validation Regularization L0 Regularization (Subset Selection) L1 Regularization (LASSO) L2 Regularization (Ridge Regression) Elastic Net: A weighted combination of L1 and L2 penalties High-Dimensional Applications: Both LASSO and ridge regression work even when we have more covariates than observations (high-dimensional case) Tyler Ransom is an Associate Professor of Economics at the University of Oklahoma.
