Each column stands for a D-SSL framework (i.e., pre-training ViT by Simsiam, pre-training ViT by MAE, and pre-training ViT by MAR). The first row shows the local feature space from client 1, the second row shows the local feature space from client 100, and the last row shows the global feature space.这张图概括 Understanding the Robustness of Distributed 的整体方法流程。阅读时先看模块之间传递的训练信号,再看作者如何把目标拆成可优化的子问题。

实验看点

实验部分建议重点看两类证据:一是作者是否把方法收益和更强数据、更长训练、更大模型区分开;二是跨模型、跨数据或跨任务迁移是否还能保留同样趋势。

局限与读法

这篇论文的结论需要结合任务设置、训练数据规模和消融实验一起看;不要只凭单个指标判断它对通用视觉表征的价值。
