About us
StatAI Lab, led by Dr. Fan Zhou at Shanghai University of Finance and Economics, focuses on the deep integration of artificial intelligence and statistics. Our research explores how statistical principles can enhance the interpretability and uncertainty quantification of AI systems, while also investigating how modern AI can advance statistical reasoning and data analysis.
Our Research Focus
Our research integrates statistical principles with deep learning and reinforcement learning to build theoretical foundations for AI models and develop practical AI algorithms. We focus on developing reliable methods to ensure robust decision-making, interpretability, and reliable uncertainty quantification in modern AI systems.
-
AI for Statistics: We connect foundation models with statistical inference by developing benchmark datasets to evaluate and enhance the statistical reasoning capabilities of large language models, and by designing agentic systems for automated statistical reasoning, including AI agents that assist in theorem proving. More broadly, we use statistical principles to improve the reliability, security, and interpretability of LLMs.
-
Methodology and Theory of Reinforcement Learning: We develop both theoretical foundations and practical methodologies for RL, focusing on error analysis and variance control in deep reinforcement learning, as well as principled distributional modeling of rewards; our work addresses challenges such as data dependence in offline settings and the validity of quantile-based representations, enabling statistically robust policy evaluation, consistent value estimation, and reliable decision-making under distribution shifts.
-
Two-Sided Market and Spatio-temporal System: We develop data-driven models and decision frameworks for dynamic two-sided markets, including supply–demand equilibrium metics, reinforcement learning based matching policy, and a suite of A/B testing methods. These approaches enable efficient matching, robust policy evaluation, and improved system performance in complex, time-evolving environments.
-
Uncertainty Quantification: Reliable AI requires principled uncertainty assessment. We develop statistically grounded methods for understanding uncertainty, reliability, and distributional behavior in modern learning systems, with applications ranging from robust statistical prediction and influence-based model assessment to trustworthy large language models and quantile-based learning for sequential decision-making.
-
Graph Representation Learning: Since network data is everywhere, we develop novel statistical methods for complex graph structures. Our work includes creating diffusion-based representation learning and addressing semi-supervised learning challenges with non-ignorable missing data.
