Traffic flow forecasting (TFF) is of great importance to the construction of Intelligent Transportation Systems (ITS). To mitigate communication burden and tackle with the problem of privacy leakage aroused by centralized forecasting methods, Federated Learning (FL) has been applied to TFF. However, existing FL-based approaches employ batch learning manner, which makes the pre-trained models inapplicable to subsequent traffic data, thus exhibiting subpar prediction performance. In this paper, we perform the first study of forecasting traffic flow adopting Online Learning (OL) manner in FL framework and then propose a novel prediction method named Online Spatio-Temporal Correlation-based Federated Learning (FedOSTC), aiming to guarantee performance gains regardless of traffic fluctuation. Specifically, clients employ Gated Recurrent Unit (GRU)-based encoders to obtain the internal temporal patterns inside traffic data sequences. Then, the central server evaluates spatial correlation among clients via Graph Attention Network (GAT), catering to the dynamic changes of spatial closeness caused by traffic fluctuation. Furthermore, to improve the generalization of the global model for upcoming traffic data, a period-aware aggregation mechanism is proposed to aggregate the local models which are optimized using Online Gradient Descent (OGD) algorithm at clients. We perform comprehensive experiments on two real-world datasets to validate the efficiency and effectiveness of our proposed method and the numerical results demonstrate the superiority of FedOSTC.

交通时间序列预测是具有挑战性的,因为来自不同位置的复杂时空动态时间序列通常具有不同的模式;并且对于相同的时间序列,模式可能随时间而变化,例如,在一天中存在显示出更强的时间相关性的某些时段。尽管最近的预测模型,特别是基于深度学习的模型,显示出有希望的结果,但它们受到时空不可知论的影响。这样的时空不可知模型采用共享参数空间,而不管时间序列位置和时间段,并且它们假设时间模式在位置之间是相似的,并且不会在时间上演变,这可能并不总是成立,从而导致次优结果。在这项工作中,我们提出了一个框架,旨在把时空不可知模型时空感知模型。为此,我们将来自不同位置的时间序列编码为随机变量,从中生成特定于位置和随时间变化的模型参数,以更好地捕捉时空动态。我们展示了如何整合的框架与规范的注意,使时空意识的注意。其次,为了补偿时空感知模型参数生成过程中引入的额外开销,提出了一种新的窗口注意机制,将复杂度从二次降低到线性,使得时空感知注意也具有竞争效率.我们在四个交通时间序列数据集上展示了强有力的经验证据,其中所提出的时空感知注意力在准确性和效率方面优于最先进的方法。这是“Towards Spatio-Temporal Aware Traffic Time Series Forecasting”的扩展版本,将出现在ICDE 2022 [1]中,包括其他实验结果。
