论文摘要
非法野生动植物偷猎正在推动生物多样性的丧失。为了打击偷猎,游骑兵巡逻庞大的保护区,用于非法偷猎活动。但是,游骑兵通常无法全面搜索如此大的公园。因此,引入了野生动植物安全保护助理(PAWS)作为机器学习方法,以帮助识别偷猎风险最高的地区。随着爪子部署到世界各地的公园,我们认识到许多公园的数据收集资源有限,因此功能集稀缺。为了确保资源不足的公园能够获得有意义的偷猎预测,我们介绍了公开可用的遥感数据来提取公园的功能。通过使用Google Earth Engine的数据,我们还将以前无法使用的动态数据纳入了以季节性趋势来丰富预测。我们自动化整个数据之间的部署管道,发现仅使用公开数据,我们将预测性能与使用公园专家手动计算的功能进行的预测相媲美。我们得出的结论是,卫星图像的包含会创建一个强大的系统,任何资源水平的公园都可以从未来几年的偷猎风险中受益。
Illegal wildlife poaching is driving the loss of biodiversity. To combat poaching, rangers patrol expansive protected areas for illegal poaching activity. However, rangers often cannot comprehensively search such large parks. Thus, the Protection Assistant for Wildlife Security (PAWS) was introduced as a machine learning approach to help identify the areas with highest poaching risk. As PAWS is deployed to parks around the world, we recognized that many parks have limited resources for data collection and therefore have scarce feature sets. To ensure under-resourced parks have access to meaningful poaching predictions, we introduce the use of publicly available remote sensing data to extract features for parks. By employing this data from Google Earth Engine, we also incorporate previously unavailable dynamic data to enrich predictions with seasonal trends. We automate the entire data-to-deployment pipeline and find that, with only using publicly available data, we recuperate prediction performance comparable to predictions made using features manually computed by park specialists. We conclude that the inclusion of satellite imagery creates a robust system through which parks of any resource level can benefit from poaching risks for years to come.
