Project Background

Housing price prediction is a classic application of machine learning in the real estate field. Accurate price prediction is not only valuable for homebuyers but also helps real estate developers, investors, and policymakers make data-driven decisions. As one of the most active regions in the U.S. real estate market, California's housing price data has rich feature dimensions, making it ideal for building prediction models.

This project is based on the California Housing Dataset, using the Random Forest Regression algorithm to build a prediction model and GridSearchCV for hyperparameter tuning, ultimately achieving an R² score of 0.805.
