Researchers have developed a new theoretical framework for understanding the generalization capabilities of deep learning models by grounding the concept of flatness in Riemannian geometry. This approach utilizes the Fisher Information Matrix (FIM) to define a reparametrization-invariant measure of sharpness, addressing limitations of traditional Euclidean measures. Experiments on MNIST and CIFAR-10 datasets demonstrate that this new metric, Riemannian sharpness, accurately tracks generalization performance and aligns with theoretical predictions regarding SGD's bias towards flatter minima.
