Figureure 1 · Global Top-K pruning vsFigure 1. Global Top-K pruning vs. our proposed SpecFlow. (a) Global Top-K pruning based on [CLS] attention can yield fragmented selections due to spiky attention distributions, often creating spatial holes within objects. (b) SpecFlow diffuses attentionderived energy on a kNN token graph and applies coverage-aware regional budgeting, yielding region-coherent retained tokens under high compression.这张可视化用来解释 Spectral Heat Flow for Conservative 学到的中间表征或对齐关系。重点看它是否支持正文里的机制判断。Figureure 2 · Ablation study on diffusion operatorsFigure 2. Ablation study on diffusion operators. Our KNN graph (built from token feature similarity) outperforms raw self-attention (Token attn) and [CLS]-initialized attention propagation ([CLS] attn).这张图/表用于判断 Spectral Heat Flow for Conservative 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。
