House Prices: Visualization & Prediction

Predict sales prices and practice different machine learning regressors. ( ⭐️ Star us on GitHub — it helps! )

Getting started with competitive data science can be quite intimidating. So I build this notebook for a quick overview of the House Prices: Advanced Regression Techniques competition. For your convenience, please view it in kaggle.

I encourage you to fork this kernel/GitHub repo, play with the code and enter the competition. Good luck!

Requirements

This project requires Python 2.7 and the following Python libraries installed:

• NumPy
• matplotlib
• seaborn
• scikit-learn
• XGBoost

You will also need to have the software installed to run and execute an iPython Notebook

Code

An ipython notebook is used for data preprocessing, feature transforming and outlier detecting. All core scripts are in file .ipynb" folder. All input data are in input folder and the detailed description of the data can be found in Kaggle.
