Global polynomial-time estimation in statistical nonlinear inverse problems via generalized stability
Sven Wang
Non-linear statistical inverse problems pose major challenges both for statistical analysis and computation. Likelihood-based estimators typically lead to non-convex and possibly m…

Statistical Learning Theory for Neural Operators
Niklas Reinhardt, Sven Wang, Jakob Zech
We present statistical convergence results for the learning of (possibly) non-linear mappings in infinite-dimensional spaces. Specifically, given a map $G_0:\mathcal X\to\mathcal Y…

The nonparametric LAN expansion for discretely observed diffusions
Sven Wang
Consider a scalar reflected diffusion , where the unknown drift function is modelled nonparametrically. We show that in the low frequency sampling case, when the…
