In the field of natural language processing (NLP), Large Language Models (LLMs) has revolutionized how computers understand and generate human language. However, along with their remarkable capabilities come challenges of hallucinations – where LLMs generate inaccurate or confusioning text. Retrieval Augmented Generation (RAG) is an approach to address these hallucinations. Let's explore how RAG works and how it can areduce LLM hallucinations.
Understanding LLM Hallucinations
LLM hallucinations occur when models generate text that is incorrect, nonsensical, or inappropriate. Despite their advanced training on vast amounts of text data, LLMs may occasionally produce hallucinations due to inherent limitations in their understanding of context, semantics, and world knowledge.
Introducing Retrieval Augmented Generation (RAG)
Retrieval Augmented Generation (RAG), where we talked about in more detail in this blog post is an approach that combines both of retrieval-based methods and generative models to enhance the quality and relevance of generated response. Unlike traditional generative models, which rely solely on learned patterns to generate responses, RAG works by retrieving relevant information from external knowledge sources.
Advantages of RAG in Addressing Hallucinations
RAG offers several advantages in addressing LLM hallucinations:
- Knowledge Base content: By retrieving contextually relevant information from external sources, RAG enriches the generative process with additional knowledge and context, reducing hallucinations.
- Contextual Understanding: RAG enables LLMs to better understand and contexts by only using external knowledge sources, improving the ability to generate an appropriate responses.
- Reduction of Errors: By retrieving from external knowledge bases, RAG reduced errors and inaccuracies in generated response, improving the overall quality and reliability of LLM outputs.
Conclusion
Retrieval Augmented Generation (RAG) is utilized in Conversational AI due it's ability to control hallucinations. These Conversational AI application including chatbots and virtual assistants with the ability to retrieve relevant information from knowledge bases to generate an accurate and informative responses.
