After using vectorRAG, I wanted to learn about graphRAG, and fortunately a course became available, so I took it. It was beneficial as I could follow along and learn through the Kind practical files, from explanations of basic concepts, data processing using real data, various query search methods... up to Hybrid RAG! There was something I actually wanted to implement, and after taking this course, I think I can immediately start using the knowledge I learned. The instructor's tone was calm and flowed smoothly, so even when listening at 1.7x speed, it wasn't bothersome and was easy to understand, allowing me to complete the course quickly! I enjoyed the course very much, instructor. I look forward to your next course as well!
