Researchers have developed a new theoretical framework to explain the phenomenon of grokking, where neural networks initially memorize training data before abruptly generalizing. The theory characterizes a shell-core topological structure in the solution space, induced by Adam's optimization dynamics and weight-shrinkage regularization. This structure explains the transition from memorization to generalization and allows for the derivation of scaling laws related to learning rate, batch size, and L2 regularization. AI
