(a) Under aggressive KV compression, SparseMM discard answer-critical visual evidence and produce incorrect predictions, suggesting observation window attention can miss sparse evidence under tight cache budgets. (b) The last query is more sensitive than earlier prompt queries to answer-relevant tokens, showing its ability to capture boundary-emergent evidence. (c) Compared with window-averaged attention, last-query attention better highlights visually important tokens and closely matches the answer’s attention distribution over visual tokens.这张可视化用来解释 Last But Not Least 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 1 · : Visual Importance Estimation under low budget on SnapKV: ObservationFigure 1: Visual Importance Estimation under low budget on SnapKV: Observation window vs. BACON这张图来自论文 PDF 的结构化抽取。当前用于辅助理解 Last But Not Least 的方法或实验,请结合正文精读段落一起看。
