Google 推出行星预测引擎，自动化地理空间建模
原标题：Planetary prediction engine: Automating global models via Earth AI
AI 摘要
Google Research 推出行星预测引擎（PPE），作为 Earth AI 计划的一部分，该实验性研究系统能自主执行从数据发现到模型训练的完整地理空间建模流程。在公共卫生、粮食安全、环境风险和社会经济等领域的测试中，PPE 相比人工专家流程显著提升了预测精度，例如将疾病健康指标的 R² 从 60.0% 提升至 76.8%，并将建模时间从数周缩短至数分钟。该系统通过多模态融合和智能数据选择，在实时疫情预测等任务中也取得了优于现有基线的表现。
