RAG vs PEFT Understanding The Difference and How They Work Together
RAG vs PEFT: Understanding the Difference and How They Work Together * A comprehensive guide to Retrieval Augmented Generation and Parameter Efficient Fine-Tuning with LoRA* The AI community has been buzzing with questions about two important concepts: ** RAG (Retrieval Augmented Generation )** and ** PEFT (Parameter Efficient Fine-Tuning) ** with LoRA (Low Rank Adaptation). Many developers are wondering: Can I use RAG to fine-tune an LLM? Should I apply RAG first, then LoRA, or vice versa? Can I teach my LLM a second language using just RAG? Let's dive deep into these technologies, understand how they work, and explore how they complement each other in the modern AI landscape. Understanding RAG: The Information Retriever What is RAG? RAG starts with a fundamental problem: your LLM has learned information up to its training cutoff, but you need current, specific, or domain-specific information that wasn't in the training data. Here's how RAG works: 1. ** Que...
