Beyond Regularity: Modeling Chaotic Mobility Patterns for Next Location Prediction

  • 引入混沌神经振荡注意力机制,动态平衡周期与随机移动模式。
  • 融合时空上下文信息,在真实数据上提升3.17%至13.11%准确率。
  • 适合处理高混沌度轨迹,适用于智慧交通与个性化导航场景。

下一位置预测是人类移动行为分析的关键任务,对智慧城市资源配置和个性化导航服务至关重要。现有方法面临两大挑战:一是难以应对周期性与混沌移动模式间的动态失衡,导致稀疏轨迹适应能力不足;二是未充分利用上下文线索,如到达时间的时序规律性——即使在混沌模式中仍存在强可预测性,因搜索空间更小。为此,本文提出CANOE(Chaotic Neural Oscillatory Attention Network),引入受生物启发的混沌神经振荡注意力机制,增强传统注意力的自适应可变性,实现对演化移动行为的均衡表征;同时设计三元组交互编码器与跨上下文注意力解码器,在统一框架中融合多模态“谁-何时-何地”上下文信息。在两个真实世界数据集上的大量实验表明,CANOE始终显著优于多种先进基线方法,在不同情况下相较最优基线提升3.17%–13.11%。特别地,模型在不同混沌程度的移动轨迹上均能保持鲁棒预测性能。消融实验证实了核心设计的有效性。代码已开源:https://github.com/yuqian2003/CANOE。

原文摘要 · Abstract (English)

Next location prediction is a key task in human mobility analysis, crucial for applications like smart city resource allocation and personalized navigation services. However, existing methods face two significant challenges: first, they fail to address the dynamic imbalance between periodic and chaotic mobile patterns, leading to inadequate adaptation over sparse trajectories; second, they underutilize contextual cues, such as temporal regularities in arrival times, which persist even in chaotic patterns and offer stronger predictability than spatial forecasts due to reduced search spaces. To tackle these challenges, we propose \textbf{\method}, a \underline{\textbf{C}}h\underline{\textbf{A}}otic \underline{\textbf{N}}eural \underline{\textbf{O}}scillator n\underline{\textbf{E}}twork for next location prediction, which introduces a biologically inspired Chaotic Neural Oscillatory Attention mechanism to inject adaptive variability into traditional attention, enabling balanced representation of evolving mobility behaviors, and employs a Tri-Pair Interaction Encoder along with a Cross Context Attentive Decoder to fuse multimodal ``who-when-where'' contexts in a joint framework for enhanced prediction performance. Extensive experiments on two real-world datasets demonstrate that CANOE consistently and significantly outperforms a sizeable collection of state-of-the-art baselines, yielding 3.17\%-13.11\% improvement over the best-performing baselines across different cases. In particular, CANOE can make robust predictions over mobility trajectories of different mobility chaotic levels. A series of ablation studies also supports our key design choices.
