The Spatial neural network model with disruptive technology for property appraisal in real estate industry

•A Spatial Neural Network (SNN) model is proposed for automatic property appraisal as required by Basel II and Ш, called Property Appraisal 4.0.•We uses disruptive technology and discover hidden neighbourhood features of real estate information in the satellite embedding vectors.•The latest deep learning technologies are also employed, such as knowledge distillation, incremental learning, and Deep-Automated Optical Inspection.•Class Activation Mapping is also adapted to reinforce the proposed spatial neural network in the model.•Experimental results show that our approach's performance is better than that of previous mainstream models, Property valuation is a complex issue that has always been the focal point for the real estate industry. The traditional valuation models used for appraisals cannot meet real-world demand anymore due to the improper processing of correlated information of nearby facilities. In this study, we propose a Spatial Neural Network (SNN) model, called Property Appraisal 4.0, that uses disruptive technology to forecast property values and discover hidden neighbourhood features of real estate information in the satellite embedding vectors. The latest deep learning technologies are also employed, such as knowledge distillation, incremental learning, and Deep-Automated Optical Inspection. Class Activation Mapping is also adapted to reinforce the proposed spatial neural network in the model. Experimental results show that our approach's performance is better than that of previous mainstream models, such as the Hedonic Pricing Model and Support Vector Machines.
