Description

Practical Machine Learning: Prediction, Trees, and Regularization in R

This **Johns Hopkins course** focuses on the **applied side of ML**: using the caret package in R to build, tune, and evaluate predictive models—without getting lost in theory. You’ll work with real datasets to solve classification and regression problems using best practices.

Algorithms You’ll Use

  • Decision trees & random forests
  • Regularized regression—ridge, lasso, elastic net
  • Support vector machines
  • Ensemble methods—bagging, boosting

Key Skills

  • Preprocessing—centering, scaling, dummy variables
  • Resampling—cross-validation, bootstrapping
  • Feature selection—recursive elimination, importance scores
  • Model comparison—ROC, AUC, RMSE

Who Should Enroll?

  • Analysts moving from descriptive to predictive analytics
  • R users wanting to apply ML without switching to Python
  • Students in the JHU Data Science Specialization
  • Researchers needing interpretable models

ML That Works in Practice

This course skips neural nets and focuses on **algorithms that work on tabular data**—the majority of real-world business problems.
