Boosting house price estimations with Multi-Head Gated Attention

Evaluating house prices is crucial for various stakeholders, including homeowners, investors, and policymakers. However, traditional spatial interpolation methods have limitations in capturing the complex spatial relationships that affect property values. To address these challenges, we have developed a new method called Multi-Head Gated Attention for spatial interpolation. Our approach builds upon attention-based interpolation models and incorporates multiple attention heads and gating mechanisms to better capture spatial dependencies and contextual information. Importantly, our model produces embeddings that reduce the dimensionality of the data, enabling simpler models like linear regression to outperform complex ensembling models. We conducted extensive experiments to compare our model with baseline methods and the original attention based interpolation model. The results show a significant improvement in the accuracy of house price predictions, validating the effectiveness of our approach. This research advances the field of spatial interpolation and provides a robust tool for more precise house price evaluation. Our GitHub repository. 1 1 Final_file/tree/main/ASI-main . contains the data and code for all datasets, which are available for researchers and practitioners interested in replicating or building upon our work. • Multi-Head Gated Attention model improves spatial interpolation for house price prediction. • Geographical and structural attention mechanisms enhance spatial feature extraction. • Embedding generation reduces data complexity, boosting model performance and accuracy. • New dataset combines Italian city data with structural and geographical attributes. • Model outperforms traditional methods, validated across multiple diverse datasets.
