Improving RAG Systems with Semantic Firewalls
Read Full Article: Improving RAG Systems with Semantic Firewalls
In the GenAI space, the common approach to building Retrieval-Augmented Generation (RAG) systems involves embedding data, performing a semantic search, and stuffing the context window with top results. This approach often leads to confusion as it fills the model with technically relevant but contextually useless data. A new method called "Scale by Subtraction" proposes using a deterministic Multidimensional Knowledge Graph to filter out noise before the language model processes the data, significantly reducing noise and hallucination risk. By focusing on critical and actionable items, this method enhances the model's efficiency and accuracy, offering a more streamlined approach to RAG systems. This matters because it addresses the inefficiencies in current RAG systems, improving the accuracy and reliability of AI-generated responses.
