Four new research papers delve into the theoretical underpinnings of generalization in neural networks. One paper establishes a necessary and sufficient condition for provable compositional generalization, focusing on structural alignment and unambiguous minimized representations, with verification in Lean 4. Another paper analyzes generalization dynamics under gradient descent with weight decay, decomposing population error and bounding prediction variation. A third paper derives a differential equation for the generalization gap, applicable to deep networks and smooth loss functions, and shows its accuracy in numerical experiments. The final paper introduces a "Rules-and-Facts" model to characterize how neural networks simultaneously learn underlying rules and memorize specific exceptions, exploring the role of overparameterization and regularization.
