CGNSDE: Conditional Gaussian Neural Stochastic Differential Equation for Modeling Complex Systems and Data Assimilation

2 code implementations10 Apr 2024 Chuanqi Chen, Nan Chen, Jin-Long Wu

Then, neural networks are supplemented to the knowledge-based model in a specific way, which not only characterizes the remaining features that are challenging to model with simple forms but also advances the use of analytic formulae to efficiently compute the nonlinear DA solution.

CharacterChat: Learning towards Conversational AI with Personalized Social Support

1 code implementation20 Aug 2023 Quan Tu, Chuanqi Chen, Jinpeng Li, Yanran Li, Shuo Shang, Dongyan Zhao, Ran Wang, Rui Yan

In our modern, fast-paced, and interconnected world, the importance of mental well-being has grown into a matter of great urgency.

CEBoosting: Online Sparse Identification of Dynamical Systems with Regime Switching by Causation Entropy Boosting

1 code implementation16 Apr 2023 Chuanqi Chen, Nan Chen, Jin-Long Wu

In addition, the CEBoosting method is applied to a nonlinear paradigm model for topographic mean flow interaction, demonstrating the online detection of regime switching in the presence of strong intermittency and extreme events.
