新研究对内存高效的AI训练梯度优化器进行基准测试

作者 PulseAugur 编辑部 · [1 个来源] · 2026-08-09 23:41

一项新研究针对四种Transformer架构，对五种梯度优化器（SGD、Adam、Adagrad、Adadelta和共轭梯度下降）与三种节省内存的策略（标准训练、梯度检查点和梯度累积）进行了基准测试。研究发现，梯度累积是在不增加GPU内存使用量的情况下降低训练损失最有效的策略。研究还显示，Adam并非总是最优的优化器，在某些架构中，Adadelta和SGD的表现优于它，而梯度检查点的有效性高度依赖于具体的模型架构。 AI

影响为选择优化器和梯度策略以降低AI模型训练的资源强度提供了实用指南。

梯度显微镜：内存高效梯度计算方法资源利用率基准测试

AI training's rising resource intensity is straining electricity supplies and carbon budgets, motivating systematic study of memory-efficient training on constrained hardware. We benchmark five gradient optimizers (SGD, Adam, Adagrad, Adadelta, and Conjugate Gradient Descent) und…
