新模型优化多阶段人工智能训练流水线的计算

研究人员开发了一个分析模型,用于理解和优化多阶段基础模型训练中的计算分配。该模型结合了无监督预训练、监督微调(SFT)和强化学习(RL),利用随机矩阵理论推导近似学习动态。研究结果表明,预训练数据对性能构成限制,更好的预训练可以降低对嘈杂监督的敏感性。研究还发现,SFT初始化可以缩短RL平台期并提高渐近RL性能,而最佳计算分配取决于监督质量和预算。 AI

影响 为优化复杂人工智能训练中的计算分配提供了一个框架,有望实现更高效的模型开发。

    arXiv:2611.13276v1 Announce Type: new Abstract: Modern foundation models are trained through multiple stages, yet how these stages interact and how compute should be allocated across them remain poorly understood. We introduce an analytically tractable high-dimensional model comb…
