Regression Models and Model Optimization

Predicting continuous outcomes accurately is one of the core tasks in modern data analysis and machine learning. This course provides a structured, reading-based pathway to understanding regression algorithms and tuning them for optimal performance. You will start with core mathematical concepts and essential terminology before exploring various regression algorithms, diagnostic techniques, and optimization strategies to prevent overfitting and improve model accuracy. What you'll learn: - Understand the foundational theory behind linear, polynomial, and regularized regression algorithms - Apply Ridge, Lasso, and ElasticNet regularization to manage feature complexity and prevent overfitting - Evaluate model performance using standard metrics such as Mean Squared Error (MSE), Root Mean Squared Error (RMSE), and R-squared - Optimize hyperparameters using systematic tuning methods like grid search and cross-validation workflows - Diagnose bias-variance tradeoffs and refine feature engineering pipelines for better predictive accuracy The course begins with foundational definitions and statistical groundwork, progresses through standard algorithms, and concludes with practical model tuning strategies. This course is designed for beginners and aspiring data practitioners looking for a clear, written guide to regression modeling without complex prerequisites.
