TL;DR: This paper proposes a general graph neural network framework designed specifically for multivariate time series data that outperforms the state-of-the-art baseline methods on 3 of 4 benchmark datasets and achieves on-par performance with other approaches on two traffic datasets which provide extra structural information.
Abstract: Modeling multivariate time series has long been a subject that has attracted researchers from a diverse range of fields including economics, finance, and traffic. A basic assumption behind multivariate time series forecasting is that its variables depend on one another but, upon looking closely, it is fair to say that existing methods fail to fully exploit latent spatial dependencies between pairs of variables. In recent years, meanwhile, graph neural networks (GNNs) have shown high capability in handling relational dependencies. GNNs require well-defined graph structures for information propagation which means they cannot be applied directly for multivariate time series where the dependencies are not known in advance. In this paper, we propose a general graph neural network framework designed specifically for multivariate time series data. Our approach automatically extracts the uni-directed relations among variables through a graph learning module, into which external knowledge like variable attributes can be easily integrated. A novel mix-hop propagation layer and a dilated inception layer are further proposed to capture the spatial and temporal dependencies within the time series. The graph learning, graph convolution, and temporal convolution modules are jointly learned in an end-to-end framework. Experimental results show that our proposed model outperforms the state-of-the-art baseline methods on 3 of 4 benchmark datasets and achieves on-par performance with other approaches on two traffic datasets which provide extra structural information.

TL;DR: In this paper, the authors present a servlet container that executes a Web tier (304), typically the presentation layer of a given Java-based application, where necessary, the edge layer communicates with code running on an origin server to respond to a given request.
Abstract: According to the invention, application developers separate their Web application into two layers: a highly distributed edge layer and a centralized origin layer. In a representative embodiment, the edge layer supports a servlet container that executes a Web tier (304), typically the presentation layer of a given Java-based application. Where necessary, the edge layer communicates with code running on an origin server to respond to a given request.

TL;DR: In this article, a customer interaction network operating system for managing interactions in a multimedia communication center has an external media layer for managing media contact between customers and the communication center, a workflow layer for processing customer interactions and routing events to enterprise agents and knowledge workers; and an internal media layer is used to manage media contact with the agents.
Abstract: A customer-interaction network operating system for managing interactions in a multimedia communication center has an external media layer for managing media contact between customers and the communication center, a workflow layer for processing customer interactions and routing events to enterprise agents and knowledge workers; and an internal media layer for managing media contact with the agents and knowledge workers. The workflow layer captures each transaction, prepares a text version of at least a portion of each non-text transaction, and extracts knowledge from the text transaction or text version of a non-text transaction to be stored in a knowledge base for later use in routing and other management functions. All transactions, text versions, and extracted knowledge is related in storage for future analysis and use.

TL;DR: In this paper, a multilayer switching device and associated technique enables simultaneous wire-speed routing at OSI layer 3, wirespeed switching at layer 2, and support multiple interfaces at layer 1.
Abstract: Multilayer switching device and associated technique enables simultaneous wire-speed routing at OSI layer 3, wire-speed switching at layer 2, and support multiple interfaces at layer 1. Implementation may be embodied using one or more integrated circuits (ASIC), RISC processor, and software, thereby providing wire-speed performance on interfaces, in various operational modes.
