Linear Regression Models — Machine Learning

Regularized linear regression analysis on the Boston Housing dataset, comparing Linear Regression, Lasso (L1), and Ridge (L2) approaches.

Overview

This project predicts the median value of owner-occupied homes (MEDV) using multiple regression techniques:

Model	Approach
Linear Regression	Baseline (no regularization)
Lasso	Pipeline + GridSearchCV
Ridge	Pipeline + GridSearchCV
Ridge	Manual (RidgeCV)
Lasso	Manual (LassoCV)

The notebook includes data preprocessing (Box-Cox transformation for skewed features), exploratory data analysis, model training with cross-validation, and a final comparison table.
