Beyond 'One Language, One Script': Quantifying Orthographic Bias in Multilingual VLMs with PuMVR

📰 ArXiv cs.AI

Learn to quantify orthographic bias in multilingual Vision-Language Models (VLMs) and its impact on users of multi-script languages, using PuMVR as a solution

advanced Published 23 Jun 2026
Action Steps
  1. Identify languages with multiple scripts used by your target audience
  2. Analyze existing VLMs for orthographic bias using metrics like accuracy and F1-score
  3. Implement PuMVR to quantify and mitigate orthographic bias in your models
  4. Evaluate the performance of your models on multi-script languages
  5. Fine-tune your models using multimodal visual reasoning to improve results
Who Needs to Know This

NLP engineers and researchers on a team can benefit from understanding orthographic bias to improve model performance for multilingual users, while product managers can use this knowledge to inform product development and ensure inclusivity

Key Insight

💡 Orthographic bias in VLMs can significantly impact model performance for users of multi-script languages, and quantifying it is crucial to improving inclusivity
