Croptrained models suffer a sharp accuracy drop when evaluated with resize, revealing reliance on spatially sensitive local cues. Figure 3: Attention collapse under image degradation. Grad-CAM visualizations for DDA, UnivFD, and NPR under different degradations. For each method, the top row shows the inputs and the bottom row shows the corresponding attention maps; within each method, the left column is the clean image and the right column is its degraded counterpart. The three methods are evaluated under resizing, JPEG compression, and blur, respectively.这张图/表用于判断 GlobalForge 的实验收益来自哪里。重点看替换、消融或跨模型设置下趋势是否一致，而不是只看单个最高分。

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。
