English(EN) From Coarse to Fine: Managing Temporal Granularity in Spatio-Temporal Data for Fine-Grained Traffic Prediction

新框架可从粗粒度数据预测细粒度交通

研究人员开发了一个名为时空细化预测器(STRP)的新框架,以解决从粗粒度采样信息预测细粒度交通数据的挑战。STRP利用树卷积处理空间依赖性,并利用反向扩张卷积进行时间外推。在六个数据集上的实验表明,STRP在准确性和效率方面显著优于现有方法,为管理交通数据系统中的时间粒度不匹配提供了实用的解决方案。 AI

影响 通过弥合数据中的时间粒度差距,为提高交通预测的准确性和效率提供了一种实用的方法。
