Abstract
一种变道预测回归模型训练方法，包括：获取第一样本运动特征，所述第一样本运动特征是根据在样本采集时间采集到的样本运动对象的运动数据得到的；获取所述第一样本运动特征对应的标准变道概率，所述标准变道概率根据所述第一样本运动特征对应的对象变道时间与所述样本采集时间之间的变道时间间隔确定，所述标准变道概率与所述变道时间间隔成负相关关系；将所述第一样本运动特征输入到待训练的变道预测回归模型中，得到所述第一样本运动特征对应的预测变道概率；根据所述预测变道概率与所述标准变道概率之间的概率差异，得到模型损失值；利用所述模型损失值调整所述变道预测回归模型中的模型参数，得到所述已训练的变道预测回归模型。
