Figureure 1 · Overview of REDI
Figureure 1 · Overview of REDIFigure 1. Overview of REDI. Four transformed views provide class-conditioned visual TF-IDF scores aligned to a reference center crop, and a separate dense pass provides incoming attention mass from final-block attention columns. Independent normalization and elementwise multiplication produce the REDI score, which ranks patches for the fixed keep, merge, and compress operator and weights aggregation. With precomputed REDI scores, the frozen backbone and unchanged classifier, the 107 token reduced path reaches 84.706% Top-1 accuracy.这张图概括 REDI 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。

Left: visual word frequency by rank for separate $K = 5 1 2$ analysis codebooks fitted at selected DINOv3 blocks, showing heavy-tailed, Zipf-like usage. Right: final block validation assignments sorted by frequency, with REDI score mass accumulated over the same visual words. The different profiles show that REDI score mass is not determined by raw frequency alone. The analysis codebooks are separate from the codebook used for $\mathrm { T F I D F _ { g t } }$这张图来自论文 PDF 的结构化抽取。当前用于辅助理解 REDI 的方法或实验,请结合正文精读段落一起看。

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。
