Mitigating Exposure Bias in Score-Based Generation of Molecular Conformations
Sijia Wang, Chen Wang, Zhenhao Zhao +2
Molecular conformation generation poses a significant challenge in the field of computational chemistry. Recently, Diffusion Probabilistic Models (DPMs) and Score-Based Generative…
Multiplex Graph Contrastive Learning with Soft Negatives
Zhenhao Zhao, Minhong Zhu, Chen Wang +4
Graph Contrastive Learning (GCL) seeks to learn nodal or graph representations that contain maximal consistent information from graph-structured data. While node-level contrasting…
Emergent route towards cooperation in interacting games: the dynamical reciprocity
Qinqin Wang, Rizhou Liang, Jiqiang Zhang +3
The success of modern civilization is built upon widespread cooperation in human society, deciphering the mechanisms behind has being a major goal for centuries. A crucial fact is,…
Social hierarchy promotes the cooperation prevalence
Rizhou Liang, Jiqiang Zhang, Guozhong Zheng +1
Social hierarchy is important that can not be ignored in human socioeconomic activities and in the animal world. Here we incorporate this factor into the evolutionary game to see w…
Oscillatory evolution of collective behavior in evolutionary games played with reinforcement learning
Si-Ping Zhang, Ji-Qiang Zhang, Li Chen +1
Large-scale cooperation underpins the evolution of ecosystems and the human society, and the collective behaviors by self-organization of multi-agent systems are the key for unders…
