📂 Dataset Overview

• train.csv: Training data (1460 rows, 81 columns)
• test.csv: Test data without SalePrice
• sample_submission.csv: Sample output format for submission
• Features include:
  • GrLivArea: Above-ground living area (sq ft)
  • OverallQual: Overall material and finish quality
  • GarageCars: Number of cars in garage
  • GarageArea: Size of garage in sq ft
  • And many more...

📊 Techniques Used

• ✅ Data cleaning (dropna())
• ✅ Exploratory Data Analysis (EDA)
• ✅ Outlier Detection & Removal using scatterplots
• ✅ Feature Selection using correlation analysis
• ✅ Scaling with StandardScaler
• ✅ Linear Regression model building
• ✅ Custom user input-based prediction using .predict()

🔍 Model Evaluation

• RMSE: 42682.00
• R² Score: 0.76

Initially, accuracy was ~60%, which improved to 76% after:

• Better feature selection
• Removing outliers
• Applying scaling
