- W2948654007 abstract "随着大量移动设备的出现，准确和高效的轨迹预测有助于提高面向位置的应用和服务的质量和水平.针对现有方法对轨迹不确定性缺乏有效建模的问题，提出了基于非参数密度估计的不确定轨迹终点预测方法.在轨迹建模及模型训练阶段，利用非参数估计对起点与终点相同的轨迹构建基于密度分布的不确定轨迹模型；在轨迹预测阶段，将待预测轨迹视为轨迹数据流，并通过KS（Kolmogorov-Smirnov）检验方法与具有相同起点的不确定轨迹模型进行匹配，其中匹配程度最高的不确定轨迹即为预测轨迹.通过真实轨迹数据集上的实验表明，与现有各类主要轨迹预测方法相比，本方法在不同条件下的预测效率与准确性都有较明显优势." @default.
