Researchers have introduced CvAdamW, a novel variant of the AdamW optimizer designed to accelerate the "grokking" phenomenon in neural networks. Grokking, where a model generalizes after memorizing training data, is often inefficient. By treating Transformer attention as a thermodynamic system and monitoring its specific heat (Cv), CvAdamW dynamically adjusts weight decay to intervene when a generalization transition is imminent. This method has demonstrated the ability to achieve grokking significantly earlier than standard training on modular arithmetic tasks, reducing mean grokking latency by over 250 epochs in some experiments. The findings suggest that neural networks may exhibit detectable precursors to generalization, which can be leveraged for more efficient training. AI
