论文摘要
新颖的分布式人工神经网络体系结构(Distana)是一种生成的,复发的图形卷积神经网络。它实现了可局部可参数侧连接的网络模块的网格或网格。 Distana专门设计用于识别空间分布的非线性动力学过程背后的因果关系。我们表明,鉴于观察到重新出现的模式,在复杂的空间波传播基准上观察到了重新出现的模式,非常适合DISTANA非常适合数据流。它即使超过数百个时间步骤也会产生稳定且准确的闭环预测。此外,它能够有效地过滤噪声 - 可以通过应用自动编码器原理或通过回顾性地调整潜在神经状态活动来进一步提高这种能力。结果证实,Distana已准备好建模现实世界时空的动力学,例如大脑成像,供应网络,水流或土壤和天气数据模式。
The novel DISTributed Artificial neural Network Architecture (DISTANA) is a generative, recurrent graph convolution neural network. It implements a grid or mesh of locally parameterizable laterally connected network modules. DISTANA is specifically designed to identify the causality behind spatially distributed, non-linear dynamical processes. We show that DISTANA is very well-suited to denoise data streams, given that re-occurring patterns are observed, significantly outperforming alternative approaches, such as temporal convolution networks and ConvLSTMs, on a complex spatial wave propagation benchmark. It produces stable and accurate closed-loop predictions even over hundreds of time steps. Moreover, it is able to effectively filter noise -- an ability that can be improved further by applying denoising autoencoder principles or by actively tuning latent neural state activities retrospectively. Results confirm that DISTANA is ready to model real-world spatio-temporal dynamics such as brain imaging, supply networks, water flow, or soil and weather data patterns.
