Housing Price Prediction using Random Forest

This repository focuses on predicting housing prices using the Random Forest Regressor from sklearn.ensemble. The project highlights insights into feature importance, hyperparameter tuning, and leveraging ensemble learning techniques for accurate predictions.

Housing Price Prediction Using Random Forest

🎯 Purpose

The purpose of this project is to:

  • Build a robust predictive model for housing price estimation using Random Forest.
  • Understand the contribution of various features to housing prices.
  • Enhance skills in ensemble modeling, feature importance analysis, and performance evaluation.

📂 Dataset

🌟 Key Learnings

  1. Feature Importance:

    • Analyzed feature significance using feature_importances_ from the Random Forest Regressor.
    • Highlighted key features like area, bedrooms, and stories that strongly influence housing prices.

  2. Hyperparameter Tuning:

    • Experimented with parameters such as n_estimators, max_depth, and min_samples_split to optimize model performance.
    • Observed the impact of different parameter settings on prediction accuracy.

  3. Evaluation Metrics:

    • Assessed model performance using metrics such as R-squared and Mean Absolute Error (MAE).
    • Compared predictions with actual housing prices to evaluate accuracy.

  4. Random Forest Capabilities:

    • Demonstrated the strength of Random Forest in handling complex feature interactions and reducing overfitting through ensemble decision trees.
