A novel statistical approach to analyze image classification

Juntong Chen, Sophie Langer, Johannes Schmidt-Hieber

ICML 2026poster

The recent statistical theory of neural networks focuses on nonparametric denoising problems that treat randomness as additive noise. Variability in image classification datasets does, however, not originate from additive noise but from variation of the shape and other characteristics of the same ob…

Understanding the Effect of GCN Convolutions in Regression Tasks

Juntong Chen, Johannes Schmidt-Hieber, Claire Donnat, Olga Klopp

AISTATS 2025poster

Graph Convolutional Networks (GCNs) have become a pivotal method in machine learning for modeling functions over graphs. Despite their widespread success across various applications, their statistical properties (e.g., consistency, convergence rates) remain ill-characterized. To begin addressing thi…
