Community structure division is a crucial problem in the field of network data analysis. Algorithms based on Markov chains are easy to use and provide promising solutions for community detection. In chain-based algorithm (i.e., MCL), flow distribution matrix transition used describe stochastic flows probabilities, respectively, network. The dynamic interaction process between probabilities MCLs manifested through an iterative updating abovementioned two matrices. As one key mechanisms MCLs,...

Robustness is one of the most important performance criteria for any rail transit network (RTN), because it helps us enhance efficiency RTN. Several studies have addressed issue RTN robustness primarily from perspectives given structures or static distributions passenger flow. An open problem that remains in fully understanding how to take spatio-temporal characteristics travel into consideration, since dynamic flow an can readily trigger unexpected cascading failures. This paper addresses...

One of the challenging topics in Intelligent Transportation Systems (ITSs) is metro passenger flow prediction. It has great practical significance for daily crowd management and vehicle scheduling flow. Recently, Graph Convolutional Networks (GCN) represent a station metros by aggregating information stations directly indirectly connected with station, improve effectiveness predicting Despite its effectiveness, neighborhood aggregation scheme also brings two limitations First, it limits to...

In recent years, multilayer networks have served as effective models for addressing and analyzing real-world systems with multiple relationships. Among these scenarios, the community detection (CD) problem is one of most prominent research hotspots. Although some on network CD (MCD) has been proposed to address this problem, studies focus only topological structures. Therefore, their algorithms cannot extract out complementary information, such node similarities low-rank features, which may...

The rise of social media has intensified fake news risks, prompting a growing focus on leveraging graph learning methods such as neural networks (GNNs) to understand post-spread patterns news. However, existing often produce less robust and interpretable results they assume that all information within the propagation is relevant item, without adequately eliminating noise from engaged users. Furthermore, inadequately capture intricate inherent in long-sequence dependencies due their use...

Several technical indicators have been proposed to assess the impact of authors and institutions. Here, we combine h-index PageRank algorithm do away with some individual limitations these two indices. Most importantly, aim take into account value differences between citations-evaluating citation sources by defining using score rather than citations. The resulting PR-index is then constructed evaluating source popularity as well publication authority. Extensive tests on available collections...

Community detection is a crucial and essential problem in the structure analytics of complex networks, which can help us understand predict characteristics functions networks. Many methods, ranging from optimization-based algorithms to heuristic-based algorithms, have been proposed for solving such problem. Due inherent complexity identifying network structure, how design an effective algorithm with higher accuracy lower computational cost still remains open Inspired by capability positive...
