Temporal Graph Signal Decomposition [PDF]

open access: yesKnowledge Discovery and Data Mining, 2021
Temporal graph signals are multivariate time series with individual components associated with nodes of a fixed graph structure. Data of this kind arises in many domains including activity of social network users, sensor network readings over time, and ...

Knowledge Graph Reasoning Based on Tensor Decomposition and MHRP-Learning

open access: yesAdvances in Multimedia, 2021
In the process of learning and reasoning knowledge graph, the existing tensor decomposition technology only considers the direct relationship between entities in knowledge graph. However, it ignores the characteristics of the graph structure of knowledge

An Efficient Subgraph Isomorphism Solver for Large Graphs

open access: yesIEEE Access, 2021
For a given pair of pattern and data graphs, the subgraph isomorphism finding problem locates all instances of the pattern graph into the data graph. For a given subgraph isomorphic image of the pattern graph in a data graph, the set of all ordered pairs

Eulerian Cycle Decomposition Conjecture for the line graph of complete graphs

open access: yesAKCE International Journal of Graphs and Combinatorics, 2019
The Eulerian Cycle Decomposition Conjecture, by Chartrand, Jordon and Zhang, states that if the minimum number of odd cycles in a cycle decomposition of an Eulerian graph G of size m is a, the maximum number of odd cycles in such a cycle decomposition is

LightGCL: Simple Yet Effective Graph Contrastive Learning for Recommendation [PDF]

open access: yesInternational Conference on Learning Representations, 2023
Graph neural network (GNN) is a powerful learning approach for graph-based recommender systems. Recently, GNNs integrated with contrastive learning have shown superior performance in recommendation with their data augmentation schemes, aiming at dealing ...

Constrained ear decompositions in graphs and digraphs [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2019
Ear decompositions of graphs are a standard concept related to several major problems in graph theory like the Traveling Salesman Problem. For example, the Hamiltonian Cycle Problem, which is notoriously N P-complete, is equivalent to deciding whether a ...

End-to-End Learning for Graph Decomposition [PDF]

open access: yesIEEE International Conference on Computer Vision, 2018
Deep neural networks provide powerful tools for pattern recognition, while classical graph algorithms are widely used to solve combinatorial problems. In computer vision, many tasks combine elements of both pattern recognition and graph reasoning.

Tucker decomposition-based Temporal Knowledge Graph Completion [PDF]

open access: yesKnowledge-Based Systems, 2020
Knowledge graphs have been demonstrated to be an effective tool for numerous intelligent applications. However, a large amount of valuable knowledge still exists implicitly in the knowledge graphs.

Method of Service Decomposition Based on Microservice Architecture [PDF]

open access: yesJisuanji kexue, 2021
The microservice decomposition of the monolithic system can effectively alleviate the problems of system redundancy and difficulty in maintenance of the monolithic architecture.However,the existing microservice decomposition methods fail to make full use
