Over the past few years, machine learning has played an increasingly vital role in every aspect of our society. There are countless applications of machine learning, from tradition topic such as image recognition or spam detection, to advanced areas like automatic customer service or secure automobile systems. This paper analyzes a popular machine learning application, namely housing price prediction, by applying a full machine learning process: feature extraction, data preparation, model selection, model training and optimization, and last, but not least, prediction and evaluation. We experiment with different algorithms: linear regression, random forest, and gradient boosting. This paper demonstrates the comparison of effectiveness of these algorithms that may help sellers and buyers to have a fair deal of their respective businesses.
