🤖 AI Summary
This study addresses the lack of evaluation and optimization frameworks for assessing the alignment capabilities of vision-language models within specific regional sociocultural contexts. To bridge this gap, the work proposes a novel paradigm termed “human-in-the-loop regional adaptation,” which achieves localized alignment through region-specific data curation and model fusion while preserving global generalization. The introduced GG-EZ method is simple yet effective, demonstrating broad applicability across large vision-language models, text-to-image diffusion models, and vision-language embedding architectures. Evaluated in a Southeast Asian case study, the approach improves cultural relevance metrics by 5–15% while maintaining over 98% of global performance, with certain scenarios even surpassing the original model’s capabilities.
📝 Abstract
While the field of vision-language (VL) has achieved remarkable success in integrating visual and textual information across multiple languages and domains, there is still no dedicated framework for assessing human-centric alignment in vision-language systems. We offer two contributions to address this gap. First, we introduce Anthropogenic Regional Adaptation: a novel paradigm that aims to optimize model relevance to specific regional contexts while ensuring the retention of global generalization capabilities. Second, we present a simple, but effective adaptation method named Geographical-generalization-made-easy (GG-EZ), which utilizes regional data filtering and model merging. Through comprehensive experiments on 3 VL architectures: large vision-language models, text-to-image diffusion models, and vision-language embedding models, and a case study in Southeast Asia (SEA) regional adaptation, we demonstrate the importance of Anthropogenic Regional Adaptation and the effectiveness of GG-EZ, showing 5-15% gains in cultural relevance metrics across SEA while maintaining over 98% of global performance and even occasionally surpassing it. Our findings establish Anthropogenic Regional Alignment as a foundational paradigm towards applicability of multimodal vision-language models in diverse regions and demonstrate a simple-yet-effective baseline method that optimizes regional value alignment while preserving global generalization.
