Computational Statistics: Feature Selection, Regularization, and Shrinkage with MATLAB
In this webinar, you will learn how to use Statistics and Machine Learning Toolbox to generate accurate predictive models from data sets that contain large numbers of correlated variables. By the end of the webinar, you will understand:
- Problems that can occur when linear regression is used to model such data sets
- How to use sequential feature selection and cross-validation to address these problems
- Alternative techniques based on regularization and shrinkage including lasso, ridge regression, and elastic net
- The characteristics of data sets that suggest regularization and shrinkage methods versus sequential feature selection
