Challenges and opportunities in RAG for LLMs
Some key challenges and opportunities in RAG include the following:
- Scalability: Efficiently handling very large knowledge bases.
- Dynamic knowledge updating: Keeping the knowledge base current.
- Cross-lingual RAG: Retrieving and generating in multiple languages.
- Multi-modal RAG: Incorporating non-text information in retrieval and generation.
Keep in mind that cross-lingual and multi-modal RAG will need specialized retrieval pipelines or adapters because standard retrieval approaches often struggle with semantic matching across languages or modalities, requiring dedicated components that can properly encode, align, and retrieve relevant information regardless of the source language or format while maintaining contextual understanding and relevance.
- Explainable RAG: Providing transparency in the retrieval and generation process.
