Research Topics:
- Nonparametric Statistical Learning We consider nonlinear functional compositional structures that generalize the linear single-index or multi- index model, and develop new algorithms to achieve the goal of obtaining the minimax nonparametric rate corresponding without suffering from the curse of dimensionality. These novel algorithms cover a wide range of tools from statistical learning, including conditional regression, local kernel regression, gra- dient estimates, nonlinear feature learning, and high dimensional classification. The proposed minimax nonparametric rate is both proved in theoretically and verified in numerical simulations.
- Theoretical Machine Learning Study theoretical analysis of neural networks, including random feature model, Weisserstein Gradient Flow, neural tangent kernels, and maximal update parameterization in hyper-parameter transfer. In particular, our research cover the topics of error landscape in the problem of learning single-index and multi-index model via neural networks. Moreover, our research cover topics of use interacting particle systems and its mean-field limit McKean-Vlasov Equation to study mathematical foundation of MLP and transformer.
- Regularity vs Singularity in Parabolic PDEs We consider the problem of regularity of solutions to different types of geometric variational problems of partially constrained free boundary, motivated by classical results on regularity vs singularity formation in heat flows of harmonic map. We also study active scalar equations where the fractional Laplacian gives many open problems, for example, Regularity vs Singularity in Surface Quasi-Geostrophic equation.
