Reliable forecasting of traffic flow requires efficient modeling of traffic data. Indeed, different correlations and influences arise in a dynamic traffic network, making modeling a complicated task. Existing literature has proposed many different methods to capture traffic networks' complex underlying spatial-temporal relations. However, given the heterogeneity of traffic data, consistently capturing both spatial and temporal dependencies presents a significant challenge. Also, as more and more sophisticated methods are being proposed, models are increasingly becoming memory-heavy and, thus, unsuitable for low-powered devices. To this end, we propose Spatio-Temporal Lightweight Graph GRU, namely STLGRU, a novel traffic forecasting model for predicting traffic flow accurately. Specifically, our proposed STLGRU can effectively capture dynamic local and global spatial-temporal relations of traffic networks using memory-augmented attention and gating mechanisms in a continuously synchronized manner. Moreover, instead of employing separate temporal and spatial components, we show that our memory module and gated unit can successfully learn the spatial-temporal dependencies with reduced memory usage and fewer parameters. Extensive experimental results on three real-world public traffic datasets demonstrate that our method can not only achieve state-of-the-art performance but also exhibit competitive computational efficiency.

LIAF-Net: Leaky Integrate and Analog Fire Network for Lightweight and Efficient Spatiotemporal Information Processing

基于Leaky Integrate and Fire(LIF)模型的脉冲神经网络(SNNs)已被应用于能量有效的时间和时空处理任务。由于生物合理的神经元动力学和简单性,LIF-SNN受益于事件驱动处理,然而,通常面临性能降低的尴尬。这可能是因为在LIF-SNN中,神经元通过尖峰信号传输信息。为了解决这个问题,在这项工作中,我们提出了一个Leaky Integrate and Analog Fire(LIAF)神经元模型,以便模拟值可以在神经元之间传输,并在此基础上构建了一个称为LIAF-Net的深度网络,以实现高效的时空处理。在时间域中,LIAF遵循传统的LIF动力学以保持其时间处理能力。在空间域中,LIAF能够通过卷积集成或全连接集成来集成空间信息。作为一个时空层,LIAF也可以与传统的人工神经网络(ANN)层联合使用。实验结果表明,LIAF-Net在bAbI问答(QA)任务上实现了与GRU和长短期记忆(LSTM)相当的性能,并在时空动态视觉传感器(DVS)数据集上实现了最先进的性能,包括MNIST-DVS,CIFAR 10-DVS和DVS 128 Gesture,与LSTM、GRU、卷积LSTM(ConvLSTM)或3D卷积(Conv 3D)构建的传统网络相比,突触权重和计算开销要少得多。与传统的LIF-SNN相比,LIAF-Net在所有这些实验中也显示出显着的准确性增益。总之…
