Researchers have identified a phenomenon called "canalization" in overparameterized neural networks, where the selection of solutions that fit training data evolves over time. This process, observed across three grokking tasks, involves weight decay pulses influencing later generalization times in an ordered manner. This ordering emerges before visible generalization, with stronger weight decay leading to earlier generalization and weaker decay leading to later generalization, even as test-loss barriers diminish.
