WebFeb 1, 2024 · Designing expressive Graph Neural Networks (GNNs) is a central topic in learning graph-structured data. While numerous approaches have been proposed to improve GNNs with respect to the Weisfeiler-Lehman (WL) test, for most of them, there is still a lack of deep understanding of what additional power they can systematically and … WebFeb 23, 2024 · To provide a general-purpose pre-training approach, offline RL needs to be scalable, allowing us to pre-train on data across different tasks and utilize expressive neural network models to acquire powerful pre-trained backbones, specialized to individual downstream tasks.
WebThe expressive power of neural networks is important for understanding deep learning. Most existing works consider this problem from the view of the depth of a network. In this paper, we study how width affects the expressiveness of neural networks. WebUniversal approximation theorems imply that neural networks can represent a wide variety of interesting functions when given appropriate weights. On the other hand, they typically do not provide a construction for the weights, but merely state that such a construction is possible. History [ edit]
WebFrom the perspectives of expressive power and learning, this work compares multi-layer Graph Neural Networks (GNNs) with a simplified alternative that we call Graph-Augmented Multi-Layer Perceptrons (GA-MLPs), which first augments node features with certain multi-hop operators on the graph and then applies learnable node-wise functions. WebThe expressive power of Graph Neural Networks (GNNs) has been studied ex-tensively through the lens of the Weisfeiler-Leman (WL) graph isomorphism test. Yet, many graphs in scientific and engineering applications come embedded in Euclidean space with an additional notion of geometric isomorphism, which is not covered by the WL framework.
