The hidden layer that makes or breaks your AI application — and why almost nobody talks about it
You’ve built a beautiful RAG pipeline. Your embeddings are state-of-the-art. Your LLM is fine-tuned. You’ve spent weeks on prompt engineering. But when users ask questions, they get garbage answers. Why?
The article discusses the importance of ranking systems in RAG (Retrieval-Augmented Generation) pipelines, emphasizing that effective ranking is crucial for delivering relevant results to users. It explains the distinction between ranking and classification, outlines various ranking methodologies such as LambdaMART, and illustrates how to implement these systems using a two-stage retrieval process that balances speed and accuracy. The article also highlights the integration of LLMs and traditional methods to enhance retrieval performance and the future of unified models that can handle both retrieval and generation tasks effectively.
