English(EN) LionVote: Per-Layer Learning Rate Adaptation for Lion

LionVote 通过逐层学习率自适应增强 Lion 优化器

研究人员开发了 LionVote,这是一种新颖的逐层学习率自适应机制,旨在优化 Lion 优化器。诊断显示,Lion 的默认学习率对于 Vision Transformer (ViT) 架构中的某些参数来说过高,导致不同层类型的有效尺度存在差异。LionVote 通过为每个参数张量维护一个复合级别来解决此问题,该级别根据梯度方向稳定性和动量健康度进行更新,并以验证损失作为决胜因素。在 ViT-Tiny/CIFAR-100 上,与标准的 Lion 优化器和 AdamW 相比,LionVote 在 top-1 准确率方面实现了轻微但统计学上显著的改进。 AI

影响 引入了一种逐层微调学习率的方法,有可能提高特定模型架构的训练效率和性能。
