English(EN) Revealing Geography-Driven Signals in Zone-Level Claim Frequency Models: An Empirical Study using Environmental and Visual Predictors

机器学习模型揭示地理数据可改善保险索赔预测

研究人员开发了一种方法,即使在位置数据有限的情况下,也能将地理信息纳入车险索赔预测模型。通过利用来自 OpenStreetMapCORINE Land Cover 的环境数据,以及来自卫星图像的视觉特征,他们提高了区域级索赔频率模型的准确性。研究发现,在 5 公里尺度上结合坐标和环境特征对线性和基于树的模型都最有益,这表明地理背景的表征比模型复杂度更重要。 AI

影响 展示了替代数据源如何改进精算模型,可能导致保险业中更准确的风险评估。
