摘要

在世界各地的城市环境中,以骚乱和抗议为表现形式的冲突时有发生。了解这些事件可能发生的地点对政策制定者来说至关重要,例如,政策制定者可以为海外旅行者提供安全区域的指导,或为当地政策制定者提供预先部署医疗援助或警力的能力,以调解与暴乱事件相关的负面影响。过去预测这些事件的工作主要集中在新闻和社交媒体的使用上,适用范围仅限于有可用数据的地区。本研究利用 ResNet 卷积神经网络和高分辨率卫星图像来估计城市环境中骚乱或抗议活动的空间分布。在全球范围内(N = 18631 起冲突事件),通过训练我们的模型来了解城市形态与骚乱事件之间的关系,我们能够预测特定城市地区发生骚乱或抗议的可能性,准确率高达 97%。这项研究有望提高我们预测和理解城市形态与冲突事件之间关系的能力,即使在数据稀缺的地区也是如此。

Predicting Protests and Riots in Urban Environments With Satellite Imagery and Deep Learning
Conflict, manifesting as riots and protests, is a common occurrence in urban environments worldwide. Understanding their likely locations is crucial to policymakers, who may (for example) seek to provide overseas travelers with guidance on safe areas, or local policymakers with the ability to pre‐position medical aid or police presences to mediate negative impacts associated with riot events. Past efforts to forecast these events have focused on the use of news and social media, restricting applicability to areas with available data. This study utilizes a ResNet convolutional neural network and high‐resolution satellite imagery to estimate the spatial distribution of riots or protests within urban environments. At a global scale (N = 18,631 conflict events), by training our model to understand relationships between urban form and riot events, we are able to predict the likelihood that a given urban area will experience a riot or protest with accuracy as high as 97%. This research has the potential to improve our ability to forecast and understand the relationship between urban form and conflict events, even in data‐sparse regions.
