They found that doubling data accelerates generalization by about 4 times, while doubling width only improves performance by around 1.2 times. The study reveals a power-law scaling relation for generalization onset time: $T{\text{grok}} \rightarrow H^{-0.27} D^{-2.04} \text{eta}^{-0.50} \text{lambda}^{-0.64}$, with data complexity being the key driver of this transition. A sharp phase boundary at weight decay $\text{lambda} > 1$ separates grokking from non-grokking configurations, indicating that implicit regularization selects low-complexity solutions during the transition.","keyPoints":["Neural networks exhibit a delayed transition to generalization known as grokking","Data complexity is the dominant factor in when this transition occurs","Doubling data accelerates generalization by about 4 times"],"whyItMatters":"Understanding these scaling laws can help predict and control transitions in overparameterized networks, potentially improving AI performance.","category":{"slug":"research","name":"Research","url":"https://digestai.news/category/research"},"entities":{"companies":[],"models":[],"people":[]},"firstPublishedAt":"2026-09-12T04:00:00Z","updatedAt":"2026-09-12T04:00:00Z","sourceCount":1,"hasPrimarySource":true,"sources":[{"outlet":"arXiv cs.AI","title":"Quantifying the Memorization-to-Generalization Transition: Scaling Laws and Phase Structure in Grokking","url":"https://arxiv.org/abs/2609.10657","publishedAt":"2026-09-12T04:00:00Z","type":"primary","primary":true,"lead":true}],"sourceNotes":null,"discussions":[],"thread":null,"cite":{"text":"Digest AI, \"Neural Networks' Grokking Transition Unveiled\", 12 September 2026, https://digestai.news/story/neural-networks-grokking-transition-unveiled","publisher":"Digest AI","title":"Neural Networks' Grokking Transition Unveiled","datePublished":"2026-09-12T04:00:00Z","url":"https://digestai.news/story/neural-networks-grokking-transition-unveiled"},"generatedBy":"Written by Digest AI's editorial model from the linked sources; the sources are the record.","license":"Headlines, digests and key points are written by Digest AI and may be quoted with a link to the story page.
