Generalization in Nonlinear Least Squares via Learned Feature Geometry
Researchers have developed a new method to understand how nonlinear least-squares models generalize. Their approach uses on-average algorithmic stability to derive error bounds for local minimizers. These bounds are linked to the geometry of the gradient model at the trained parameters, offering insights that depend on learned geometry rather than just parameter count. AI
