PM2.5-GNN: A Domain Knowledge Enhanced Graph Neural Network For PM2.5 Forecasting
Shuo Wang, Yanran Li, Jiang Zhang +3
When predicting PM2.5 concentrations, it is necessary to consider complex information sources since the concentrations are influenced by various factors within a long period. In th…
Understanding the mesoscopic scaling patterns within cities
Lei Dong, Zhou Huang, Jiang Zhang +1
Understanding quantitative relationships between urban elements is crucial for a wide range of applications. The observation at the macroscopic level demonstrates that the aggregat…
Link Prediction via Graph Attention Network
Weiwei Gu, Fei Gao, Xiaodan Lou +1
Link prediction aims to infer missing links or predicting the future ones based on currently observed partial networks, it is a fundamental problem in network science with tremendo…
Gumbel-softmax Optimization: A Simple General Framework for Combinatorial Optimization Problems on Graphs
Jing Liu, Fei Gao, Jiang Zhang
Many problems in real life can be converted to combinatorial optimization problems (COPs) on graphs, that is to find a best node state configuration or a network structure such tha…
A General Deep Learning Framework for Network Reconstruction and Dynamics Learning
Zhang Zhang, Yi Zhao, Jing Liu +4
Many complex processes can be viewed as dynamical systems on networks. However, in real cases, only the performances of the system are known, the network structure and the dynamica…
The Hidden Flow Structure and Metric Space of Network Embedding Algorithms Based on Random Walks
Weiwei Gu, Li Gong, Xiandao Lou +1
Network embedding which encodes all vertices in a network as a set of numerical vectors in accordance with it's local and global structures, has drawn widespread attention. Network…
Exploring multi-layer flow network of international trade based on flow distances
Bin Shen, Jiang Zhang, Qiuhua Zheng
Based on the approach of flow distances, the international trade flow system is studied from the perspective of multi-layer flow network. A model of multi-layer flow network is pro…
Flow Distances on Open Flow Networks
Liangzhu Guo, Xiaodan Lou, Peiteng Shi +3
Open flow network is a weighted directed graph with a source and a sink, depicting flux distributions on networks in the steady state of an open flow system. Energetic food webs, e…
The Hidden Geometry of Attention Diffusion
Cheng-Jun Wang, Lingfei Wu, Jiang Zhang +1
We propose a geometric model to quantify the dynamics of attention in online communities. Using clicks as a proxy of attention, we find that the diffusion of collective attention i…
Hierarchicality of Trade Flow Networks Reveals Complexity of Products
Peiteng Shi, Jiang Zhang, Bo Yang +1
With globalization, countries are more connected than before by trading flows, which currently amount to at least 36 trillion dollars. Interestingly, approximately 30-60 percent of…
The Metabolism and Growth of Web Forums
Lingfei Wu, Jiang Zhang, Min Zhao
We view web forums as virtual living organisms feeding on user's attention and investigate how these organisms grow at the expense of collective attention. We find that the "body m…
Capabilities' Substitutability and the "S" Curve of Export Diversity
Hongmei Lei, Jiang Zhang
Product diversity, which is highly important in economic systems, has been highlighted by recent studies on international trade. We found an empirical pattern, designated as the "S…
Allometry and Dissipation of Ecological Flow Networks
Jiang Zhang, Lingfei Wu
An ecological flow network is a weighted directed graph in which nodes are species, edges are "who eats whom" relationships and weights are rates of energy or nutrients transfer be…
Common Patterns of Energy Flow and Biomass Distribution on Weighted Food Webs
Jiang Zhang, Yuanjing Feng
Weights of edges and nodes on food webs which are available from the empirical data hide much information about energy flows and biomass distributions in ecosystem. We define a set…
The Decentralized Structure of Collective Attention on the Web
Lingfei Wu, Jiang Zhang
Background: The collective browsing behavior of users gives rise to a flow network transporting attention between websites. By analyzing the structure of this network we uncovered…
The "S" Curve Relationship between Export Diversity and Economic Size of Countries
Lunchao Hu, Kailan Tian, Xin Wang +1
The highly detailed international trade data among all countries in the world during 1971-2000 shows that the kinds of export goods and the logarithmic GDP (gross domestic producti…
Accelerating Growth and Size-dependent Distribution of Human Activities Online
Lingfei Wu, Jiang Zhang
Research on human online activities usually assumes that total activity increases linearly with active population , that is, . However, we find examples o…
Exact Solution for Optimal Navigation with Total Cost Restriction
Yong Li, Dong Zhou, Yanqing Hu +2
Recently, Li \textit{et al.} have concentrated on Kleinberg's navigation model with a certain total length constraint , where is the number of total nodes and is a c…
Allometric Scaling of Countries
Jiang Zhang, Tongkui Yu
As huge complex systems consisting of geographic regions, natural resources, people and economic entities, countries follow the allometric scaling law which is ubiquitous in ecolog…
Scaling Behaviors of Weighted Food Webs as Energy Transportation Networks
Jiang Zhang, Liangpeng Guo
Food webs can be regarded as energy transporting networks in which the weight of each edge denotes the energy flux between two species. By investigating 21 empirical weighted food…
