Graph isomorphism and Gaussian boson sampling
Special Matrices, 2021 We introduce a connection between a near-term quantum computing device, specifically a Gaussian boson sampler, and the graph isomorphism problem. We propose a scheme where graphs are encoded into quantum states of light, whose properties are then probed ...

Graph Sampling Through Graph Decomposition and Reconstruction Based on Kronecker Graphs [PDF]
Journal of Systemics, Cybernetics and Informatics, 2022 The connectedness of the social network gives rise to a new challenge of how to efficiently sample the network and keep the graph properties and topology properties as well.

Multi-Channel Sampling on Graphs and Its Relationship to Graph Filter Banks
IEEE Open Journal of Signal Processing, 2023 In this article, we consider multi-channel sampling (MCS) for graph signals. We generally encounter full-band graph signals beyond the bandlimited ones in many applications, such as piecewise constant/smooth graph signals and union of bandlimited graph ...

Evaluating graph neural networks under graph sampling scenarios [PDF]
PeerJ Computer Science, 2022 Background It is often the case that only a portion of the underlying network structure is observed in real-world settings. However, as most network analysis methods are built on a complete network structure, the natural questions to ask are: (a) how ...

Efficient Non-Sampling Graph Neural Networks
Information, 2023 A graph is a widely used and effective data structure in many applications; it describes the relationships among nodes or entities. Currently, most semi-supervised or unsupervised graph neural network models are trained based on a very basic operation ...

Graph Sampling for Map Comparison
ACM Transactions on Spatial Algorithms and Systems, 2023 Comparing two road maps is a basic operation that arises in a variety of situations. A map comparison method that is commonly used, mainly in the context of comparing reconstructed maps to ground-truth maps, is based on graph sampling .
