Ideas:
“  I am currently working on new computational frameworks that bridge social science theory and machine learning. My recent projects include the development of Hierarchical Evolutionary Agent Simulation for cross-scale agent-based simulation; Structural Equation-VAE for interpretable representation learning in tabular data, and empirical studies on sustainability, citizen–government co-production, and state-owned enterprise reform in China.  ”
