Paper explains LLM training bottleneck with universal 1/3 time scaling

Researchers have identified a universal one-third time scaling in the learning process of peaked probability distributions, a phenomenon observed in large language models. This behavior, stemming from the use of softmax and cross-entropy, creates a fundamental optimization bottleneck leading to slow power-law convergence of the loss and gradients. The findings offer a mechanistic explanation for observed neural scaling and suggest avenues for enhancing LLM training efficiency. AI

    Universal One-third Time Scaling in Learning Peaked Distributions

    arXiv:2602.03685v2 Announce Type: replace-cross Abstract: Training large language models (LLMs) is computationally expensive, partly because the loss exhibits slow power-law convergence whose origin remains debatable. Through systematic analysis of toy models and empirical evalua…
