Machine Learning, Architectural Styles and Property Values
将传统特征价格模型与专家和机器学习分类的建筑风格结合，估计建筑风格对住宅销售价格的影响，发现不同风格存在显著价格差异，且机器学习分类在批量评估中可达到与专家相当的可靠性。
Abstract This paper couples a traditional hedonic model with architectural style classifications from human experts and machine learning (ML) enabled classifiers to estimate sales price premia over architectural styles, both at the building and the neighborhood-level. We find statistically and economically significant price differences for houses from distinct architectural styles across an array of specifications and modeling assumptions. Comparisons between classifications from ML models and human experts illustrate the conditions under which ML classifiers may perform at least as reliable as human experts in mass appraisal models. Hedonic estimates illustrate that the impact of architectural style on price is attenuated by properties with less well-defined styles and we find no evidence for differential price effects of Revival or Contemporary architecture for new construction.
