本文构建聚焦语义粒度与文本特异性的零样本识别基准,系统评估VLM,发现其偏好中等细粒度概念且难以辨别细微错误描述,微调也无法根本解决泛化缺陷。

摘要:

本文提出了用于评估视觉-语言模型(VLM)在零样本识别中表现的新型基准,重点关注粒度和特异性。尽管VLM在图像描述等任务中表现出色,但它们在开放世界场景中仍面临挑战。我们的基准测试VLM在跨语义粒度层级理解概念的一致性,以及它们对不同文本特异性的响应。研究结果表明,VLM偏好中等细粒度的概念,并且在处理特异性方面存在困难,常常会误判与其训练数据不同的文本。大量评估揭示了当前VLM的局限性,尤其是在区分正确描述与细微错误描述方面。虽然微调能带来一定改进,但并不能完全解决这些问题,这凸显了现实世界应用需要具备更强泛化能力的VLM。本研究为VLM的局限性提供了洞见,并为开发更鲁棒的模型提出了方向。

英文摘要:

This paper presents novel benchmarks for evaluating vision-language models (VLMs) in zero-shot recognition, focusing on granularity and specificity. Although VLMs excel in tasks like image captioning, they face challenges in open-world settings. Our benchmarks test VLMs' consistency in understanding concepts across semantic granularity levels and their response to varying text specificity. Findings show that VLMs favor moderately fine-grained concepts and struggle with specificity, often misjudging texts that differ from their training data. Extensive evaluations reveal limitations in current VLMs, particularly in distinguishing between correct and subtly incorrect descriptions. While fine-tuning offers some improvements, it doesn't fully address these issues, highlighting the need for VLMs with enhanced generalization capabilities for real-world applications. This study provides insights into VLM limitations and suggests directions for developing more robust models.
