Car price prediction using Linear Regression with real-world Pakistani car data.
π Pakistani Car Price Prediction using Linear Regression
π Project Overview
This project demonstrates how Machine Learning can be learned through research and applied to a real-world problem. Linear Regression is used to predict car prices based on Pakistani car market data.
The goal of this project is to understand Linear Regression practically, analyze its performance, visualize predictions, and identify its limitations.
π― Objective
-
Learn Machine Learning through research.
-
Apply Linear Regression in a real project.
-
Predict car prices using real-world data.
-
Analyze model behavior and limitations.
-
Connect ML theory with real results.
π§ Machine Learning Algorithm
Linear Regression
Linear Regression is a supervised machine learning algorithm used to predict continuous values by learning linear relationships between input features and the target variable.

π Key Insights
-
Linear Regression captures general pricing trends.
-
High-priced cars are under-predicted.
-
Low-priced cars are sometimes over-predicted.
-
Year is the strongest influencing feature.
-
Data skewness and outliers affect model accuracy.
-
Linear Regression works best as a baseline model.
-
Linear assumption restricts performance.
-
Sensitive to outliers.
-
Limited feature set.
-
Categorical encoding impact.
π Future Improvements
-
Add mileage, engine size, transmission.
-
Use One-Hot Encoding.
-
Apply Polynomial Regression.
-
Compare with Random Forest and XGBoost.
