LAYRA v2 (Large Academic Visual RAG Agent)
LAYRA v2 is a specialized Visual RAG system designed for the ethnopharmacology of Sceletium tortuosum. It processes full PDF pages as images, preserving layout and visual information, and uses a hybrid retrieval stack.
Architecture
- Visual Encoder: ColQwen 2.5 (ColBERT + Qwen-VL)
- Retrieval: Hybrid (Sparse BM25 + Dense ColBERT)
- Reranking: LLM-based Reranking (Generative Listwise)
- Vector DB: Milvus 2.5.5
- Infrastructure: Docker Compose (Lean Stack)
Performance
| Metric | Score |
