The LLM Bottleneck: Why Open-Source Vision LLMs Struggle with Hierarchical Visual Recognition
🤖AI Summary
Research reveals that open-source large language models (LLMs) lack hierarchical knowledge of visual taxonomies, creating a bottleneck for vision LLMs in hierarchical visual recognition tasks. The study used one million visual question answering tasks across six taxonomies to demonstrate this limitation, finding that even fine-tuning cannot overcome the underlying LLM knowledge gaps.
Key Takeaways
- →Open-source LLMs demonstrate poor understanding of established biological and visual taxonomies
- →This knowledge gap creates a bottleneck preventing vision LLMs from performing hierarchical visual recognition effectively
- →The research utilized one million four-choice VQA tasks across six taxonomies and four image datasets to validate findings
- →Fine-tuning vision LLMs showed limited improvement, with base LLMs improving more than vision models
- →Vision LLMs cannot achieve hierarchical visual understanding until underlying LLMs possess proper taxonomy knowledge
