English(EN) Asymmetric Bidirectional Predictive Dynamics in Google Search and COVID-19 Time Series: A Multi-Horizon Forecast-Error Analysis

新的分析方法揭示了Google搜索与COVID-19数据之间复杂的预测联系

作者 PulseAugur 编辑部 · [1 个来源] ·

本研究论文介绍了一种分析Google搜索趋势与COVID-19时间序列数据之间预测关系的新方法。该研究利用LightGBM进行多期预测，并引入了预测误差分布熵（FEDE）这一指标以及传统的RMSE，以捕捉方向性预测动态。研究结果表明，预测效应取决于所使用的指标、关系的走向以及预测期，并警示不要将聚合模式推断到单个时间点或推断因果关系。 AI

影响 引入了分析时间序列数据的新方法，可能改进流行病预测模型。

    arXiv:2610.28563v1 Announce Type: new Abstract: Online search activity is widely used as a digital trace of information seeking during epidemics, but its predictive value is often reduced to correlation, a selected lag, or a single forecast-error score. We examine eight pre-speci…
