• Explore and compare traditional methods (e.g. linear regression, decision trees) with modern ML algorithms.
• Get hands-on experience with data preprocessing, feature selection, and model evaluation.
• Tune model performance through hyperparameter adjustment and cross-validation.

🛠️ Technologies Used

• Python
• Pandas: For data wrangling and cleaning.
• NumPy: For numerical operations.
• Matplotlib / Seaborn: For data visualization.
• Scikit-learn: For training, evaluating, and comparing different ML models.

📊 Key Features

• Data import and cleansing pipeline.
• Feature engineering and normalization.
• Application of multiple prediction models:
  • Linear Regression
