论文摘要
在这项研究中，我们开发了一个新颖的框架，以评估马里兰州各个地区（邮政编码）的热风险，借助两个常用的指标，即暴露和脆弱性。我们的方法通过开发其相应的特征向量并随后计算指标特定的参考向量来量化上述两个指标中的每个指标，从而通过将数据点聚集到经验风险谱的尾端来表示高风险环境。所提出的框架规定了基于信息理论熵的聚合方法的使用情况不同，其熵的视图在本质上是主观的，更重要的是，使用余弦相似性和未知参考点的余弦相似性概括了风险评估的概念。
In this study, we develop a novel framework to assess health risks due to heat hazards across various localities (zip codes) across the state of Maryland with the help of two commonly used indicators i.e. exposure and vulnerability. Our approach quantifies each of the two aforementioned indicators by developing their corresponding feature vectors and subsequently computes indicator-specific reference vectors that signify a high risk environment by clustering the data points at the tail-end of an empirical risk spectrum. The proposed framework circumvents the information-theoretic entropy based aggregation methods whose usage varies with different views of entropy that are subjective in nature and more importantly generalizes the notion of risk-valuation using cosine similarity with unknown reference points.
