Soundness Evaluation of Stone Walls in Kanazawa Castle by Self-Organizing Maps (SOM)

Abstract

In this study, stone walls of Kanazawa Castle were clustered using Self-Organizing Maps (SOM) based on the basic information and inspection records of the stone walls described in the “stone wall chart”. In addition, the soundness of stone walls is evaluated by analyzing the characteristics of the stone walls where deformation/displacement are observed, based on the measurement/monitoring data and examination results for countermeasure. Finally, we attempted to acquire data that would contribute to the prioritization of countermeasures.
