新的 nGPT 训练方法将 MoE 模型所需的 token 数量减半

研究人员开发了一种名为归一化 Transformer (nGPT) 的新训练方法,该方法将模型参数和激活限制在单位超球面上,以改进表示学习。这一方法在最近的 arXiv 论文中进行了详细介绍,包括 Logit Gradient Preconditioning、Logarithmic Learning Rate Decay 和 GatedAdamW 等技术。当应用于混合 Mamba-2--Transformer Mixture-of-Experts (MoE) 模型时,与具有相似架构的非归一化模型相比,nGPT 方法在训练 token 数量大约减半的情况下实现了相当的验证损失。 AI

影响 这种新的训练方法可以显著降低训练大型语言模型的计算成本。

    训练 nGPT

    arXiv:2608.01284v1 Announce Type: new Abstract: The normalized Transformer (nGPT) realizes hyperspherical representation learning by constraining model parameter vectors and activation vectors to the unit hypersphere. In this paper, we describe a practical training recipe for nGP…
