Researchers have quantified the transition from memorization to generalization in neural networks, a process known as grokking. The study found that data complexity is the main factor driving this transition, with scaling laws identified.

Key facts

A study mapped the transition from memorization to generalization in neural networks, termed grokking.
Data complexity was identified as the primary driver of this regime transition.
Doubling data accelerates generalization by approximately four times.
A distinct phase boundary at weight decay values of approximately 1.0 separates grokking from non-grokking configurations.
Weight norms compressed monotonically during the transition, suggesting implicit regularization favors low-complexity solutions.
