In this comprehensive Simplilearn video, we dive into key AI tuning techniques, starting with RAG (Retrieval-Augmented Generation), which enhances pre-trained language models by integrating external data retrieval to improve response accuracy. We then explore Fine-Tuning, where pre-trained models are adjusted using specific datasets to optimize performance for targeted tasks. Next, we cover Prompt Tuning, a more lightweight approach that focuses on refining input prompts rather than retraining models. Throughout the video, we compare these methods based on their approach, purpose, use cases, and data dependency, while also highlighting their similarities, such as their shared goal of optimizing AI outputs. Whether you're new to AI or an experienced professional, this video provides a detailed look into these essential techniques, helping you understand when and how to apply them effectively.
