Heterogeneous information networks (HINs) are widely employed for describing real-world data with intricate entities and relationships. To automatically utilize their semantic information, graph neural architecture search has recently been developed various tasks of HINs. Existing works, on the other hand, show weaknesses in instability inflexibility. address these issues, we propose a novel me...

Abstract The delay-causing text data contain valuable information such as the specific reasons for delay, location and time of disturbance, which can provide an efficient support prediction train delays improve guidance control efficiency. Based on operation Wuhan–Guangzhou high-speed railway, relevant algorithms in natural language processing field are used to process data. It also integrates ...

Routing strategies under the aegis of dynamic traffic assignment have been proposed in literature to optimize system performance. However, challenges persisted their deployment ability and effectiveness due inherent strong assumptions on traveler behavior availability network-level real-time information, high computational burden associated with computing network-wide flows real-time. To addres...

With rapid development in the Internet technology, more organizations are becoming vulnerable to potential cyber attacks. Therefore, in order to protect private information and computer resources in information systems, risk analysis and propagation need to be studied. However, the existing risk models, especially risk analysis model, present mechanisms for risk management, and some risk propag...

Identifying influential spreaders is an important issue in understanding the dynamics of information diffusion in social networks. It is to find a small subset of nodes, which can spread the information or influence to the largest number of nodes. The conventional approaches consider information diffusion through the network in a coarse-grained manner, without taking into account the topical fe...

A system structure, i.e., how elements of a system are connected, is a key factor for information retention and transmission through its elements. From the system dynamics, i.e., the states of the elements over time, we measure the system’s ability to propagate information through its elements as the pairwise mutual information (pMI) between the elements at moments t and t + L, where L is the m...
