Mastering Data Cleaning for Fine-Tuning LLMs and RAG Architectures
In the rapidly advancing field of artificial intelligence, data cleaning has become a mission-critical step in ensuring the success of Large Language Models (LLMs) and Retrieval-Augmented Generation (RAG) architectures. This blog emphasizes the importance of high-quality, structured data in preventing AI model hallucinations, reducing algorithmic bias, enhancing embedding quality, and improving information retrieval accuracy. It covers essential AI data preprocessing techniques like deduplication, PII redaction, noise filtering, and text normalization, while spotlighting top tools such as IBM Data Prep Kit, AI Fairness 360, and OpenRefine. With real-world applications ranging from LLM fine-tuning to graph-based knowledge systems, the post offers a practical guide for data scientists and AI engineers looking to optimize performance, ensure ethical compliance, and build scalable, trustworthy AI systems.
