AI grokking mechanism linked to low-loss region misalignment

Researchers have identified a new mechanism behind 'grokking,' a phenomenon where AI models exhibit delayed generalization after overfitting training data. Their analysis framework, based on the geometry of low-loss regions, suggests that grokking occurs when the training and validation data partitions induce misaligned low-loss regions. In a specific counterexample using transformers, a symmetry-preserving split prevented grokking, indicating that training hyperparameters alone are insufficient when these regions are not aligned.
