摘要:

房屋销售价格是根据交易参与者的经济利益形成的,包括政府,房地产经纪人和购买或出售房产的公众。建立准确的房地产价格预测模型是房地产市场面临的一个重大挑战。这项工作使用2010年1月至2019年11月的十年实际数据集开发了一个房地产价格分类模型。房地产数据集是公开的,并从佛罗里达州的Volusia县财产评估网站检索。此外,还收集了国内生产总值、消费者价格指数、生产者价格指数、房价指数和有效联邦基金利率等社会经济因素,并将其用于预测模型。为了解决这个案例研究问题,采用了几种强大的机器学习算法,即逻辑回归,随机森林,投票分类器和XGBoost。它们与目标编码相结合,以开发准确的房地产销售价格预测模型,旨在预测收盘销售价格是大于还是小于上市销售价格。为了评估模型的性能,确定模型的准确度、精确度、召回率、分类F1分数和出错率。在所研究的四种机器学习算法中,与其他模型相比,XGBoost提供了优越的结果和模型的鲁棒性。开发的模型可以帮助房地产投资者,抵押贷款机构和金融机构做出更明智的决策。

英文摘要:

Home sale prices are formed given the transaction actors economic interests, which include government, real estate dealers, and the general public who buy or sell properties. Generating an accurate property price prediction model is a major challenge for the real estate market. This work develops a property price classification model using a ten year actual dataset, from January 2010 to November 2019. The real estate dataset is publicly available and was retrieved from Volusia County Property Appraiser of Florida website. In addition, socio-economic factors such as Gross Domestic Product, Consumer Price Index, Producer Price Index, House Price Index, and Effective Federal Funds Rate are collected and used in the prediction model. To solve this case study problem, several powerful machine learning algorithms, namely, Logistic Regression, Random Forest, Voting Classifier, and XGBoost, are employed. They are integrated with target encoding to develop an accurate property sale price prediction model with the aim to predict whether the closing sale price is greater than or less than the listing sale price. To assess the performance of the models, the accuracy, precision, recall, classification F1 score, and error rate of the models are determined. Among the four studied machine learning algorithms, XGBoost delivers superior results and robustness of the model compared to other models. The developed model can facilitate real estate investors, mortgage lenders and financial institutions to make better informed decisions.
