Machine learning of (1+1)-dimensional directed percolation based on raw and shuffled configurations
Shen Jianmin, Wang Shanshan, Li Wei +6
Machine learning (ML) can process large sets of data generated from complex systems, which is ideal for classification tasks as often appeared in critical phenomena. Meanwhile ML t…
Supervised, semi-supervised, and unsupervised learning of the Domany-Kinzel model
Kui Tuo, Wei Li, Shengfeng Deng +1
The Domany Kinzel (DK) model encompasses several types of non-equilibrium phase transitions, depending on the selected parameters. We apply supervised, semi-supervised, and unsuper…
The critical behavior of Hegselmann-Krause opinion model with smart agents
Yueying Zhu, Jian Jiang, Wei Li
The Hegselmann-Krause (HK) model allows one to characterize the continuous change of agents' opinions with the bounded confidence threshold . To consider the heterogen…
Analytic sensitivity analysis for models with correlated input variables
Yueying Zhu, Qiuping A Wang, Wei Li +1
An analytic formula is proposed to characterize the variance propagation from correlated input variables to the model response, by using multi-variate Taylor series. With the formu…
