Researchers have developed a new theory to explain why deep neural networks generalize, focusing on a pointwise approach for fully connected networks. This framework introduces the pointwise Riemannian Dimension, derived from layer-wise feature representations, to establish tighter generalization bounds than previous methods. The theory identifies mathematical principles underlying deep network tractability and empirically shows the dimension captures implicit biases of optimizers and exhibits feature compression. AI
