• Random Forest

Hyperparameter Tuning

Used RandomizedSearchCV for hyperparameter tuning of the RandomForestRegressor to achieve the best performance.

Results

The Random Forest model provided the best performance with optimal hyperparameters, effectively predicting laptop prices based on the given features.

Technologies Used

• Python: For data processing and model building.
• Pandas & NumPy: For data manipulation.
• Scikit-Learn: For machine learning algorithms.
• Seaborn & Matplotlib: For data visualization.

Visualizations

Visualized the model's accuracy using scatter and regression plots.

Conclusion

The project successfully built a model to predict laptop prices with high accuracy using Random Forest with hyperparameter tuning.
