Abstract: Interleaved multimodal in-context learning (ICL) lets frozen large vision-language models (LVLMs) acquire new tasks from a handful of image-text-answer demonstrations, yet it remains fragile: demonstrations bind to the wrong images, redundant exemplars crowd out informative ones, and noisy answers are copied verbatim into predictions.

摘要:交错式多模态上下文学习(ICL)允许冻结的大型视觉语言模型(LVLM)通过少量图像-文本-答案演示来获取新任务,但它仍然很脆弱:演示会绑定到错误的图像,冗余的示例会挤占信息量大的示例,且嘈杂的答案会被逐字复制到预测中。

We present AVA, a training-free framework that organizes the demonstration pipeline of multimodal ICL into three composable stages. A Thread-Resolved Decomposer (TRD) segments the interleaved context into per-sample threads and re-stitches them with explicit boundaries, restoring image-text binding.

我们提出了 AVA,这是一个无需训练的框架,将多模态 ICL 的演示流程组织为三个可组合的阶段。线程解析分解器(TRD)将交错的上下文分割为每个样本的线程,并用明确的边界重新拼接它们,从而恢复图像与文本的绑定。

An Influence-scored Demonstration Selector (IDS) estimates each candidate’s marginal influence with one extra forward pass, removes redundancy, and orders the survivors by descending value. A Weak-to-Strong Consistency Calibration (WSC) module scores each demonstration by a weak sibling model’s reconstruction confidence and softly reweights its contribution during decoding.

影响评分演示选择器(IDS)通过额外的一次前向传递来估计每个候选者的边际影响,去除冗余,并按价值降序排列剩余的示例。弱到强一致性校准(WSC)模块通过弱同级模型的重构置信度对每个演示进行评分,并在解码过程中对其贡献进行软加权。

On five vision-language benchmarks with interleaved 4-shot prompts, AVA improves the strongest same-setting baseline by +1.7 points on average, with gains of up to +2.4 points on VizWiz, shrinks the require-visual performance gap on ScienceQA-IMG, and retains most of its gain under 30% noisy demonstrations, at a 26% latency overhead that an offline cache amortizes. No gradients are ever computed; the LVLM stays frozen.

在五个带有交错 4-shot 提示的视觉语言基准测试中,AVA 将最强的同类基线平均提高了 1.7 个百分点,在 VizWiz 上增益高达 2.4 个百分点,缩小了 ScienceQA-IMG 上对视觉需求性能的差距,并在 30% 噪声演示下保留了大部分增益,同时仅产生 26% 的延迟开销,且该开销可通过离线缓存摊销。过程中不计算任何梯度;LVLM 保持冻结状态。
