📝 摘要(中文)

上下文引导是模型在输入中让辅助上下文影响输出的倾向,无论该上下文是否相关、真实或有意义。尽管在单模态语言模型中已有机制性解释,但在视觉语言模型(VLMs)中的表现尚未得到充分研究。为此,本文提出了ENTRAP-VL,一个结构化的双模态工具,旨在深入探讨VLMs中的上下文引导现象。该工具包含1500个项目,分为文本引导流和视觉引导流,提供了一个系统化的评估框架,以便研究者能够严谨地研究这一现象。我们将公开发布该数据集及其文档。

🔬 方法详解

问题定义:本文旨在解决视觉语言模型中上下文引导现象的研究不足,现有方法未能提供有效的评估工具。

核心思路:提出ENTRAP-VL,通过双模态的结构化工具,系统性地分析文本和视觉上下文对模型输出的影响。此设计旨在揭示上下文引导的双重性及其在VLMs中的独特表现。

技术框架:ENTRAP-VL包含1500个项目,分为文本引导流(包含八种上下文条件)和视觉引导流(三种上下文条件),并通过一个分类法组织。

关键创新:最重要的创新在于提出了一个双模态的评估工具,能够独立分析文本和视觉上下文的引导效应,这是以往单模态研究所无法实现的。

关键设计:数据集的构建遵循特定的分类法,考虑上下文与项目的关联性及其真实性,确保了评估的系统性和全面性。

📄 摘要(原文)

Contextual entrainment is the tendency of a model to let auxiliary context in its input pull its output, independently of whether that context is relevant, true, or even meaningful. Recently, it has been identified and given a mechanistic account in unimodal language models. Whether and how it manifests in vision-language models (VLMs) is, by contrast, largely unexamined, and the field lacks a purpose-built instrument with which to investigate it. We take the position that studying contextual entrainment in VLMs requires more than porting an existing text-only benchmark to the multimodal setting: it requires a taxonomically structured, dual-modality instrument whose conditions are constructed around the item at hand (the depicted image in the textual stream, the textual query in the visual stream). We argue that the move to VLMs is substantive rather than incremental. It makes entrainment a dual phenomenon, drivable independently by textual and by visual context, and it opens a veracity distinction (context that is false of the depicted scene yet possible in the world) that has no counterpart in the unimodal, world-knowledge-only formulation of prior work. To make this position concrete and actionable, we introduce ENTRAP-VL (ENTRainment Assessment Probe for Vision and Language), a manually curated dataset of 1,500 items across eight categories, organized by a taxonomy that spans two axes, i.e., the association of context with the item and its relationship to truth, and split into a textual-entrainment stream (eight context conditions) and a visual-entrainment stream (three context conditions). We do not claim to measure entrainment in any particular model; we provide the instrument, the taxonomy that motivates it, and the evaluation protocols it enables, so that the community can investigate the phenomenon rigorously. We will release the dataset and its documentation publicly.
