From RAG implementation to performance evaluation
Practical AI Development in 9 Hours

Advances in AI technology have increased the usability of RAG systems, but the process of learning and implementing them remains challenging. I, too, faced many challenges when first learning RAG, and that experience inspired me to plan this course.

The course focuses on building a working system based on step-by-step exercises. It covers not only basic implementations but also advanced techniques for improving search quality and performance evaluation, providing practical knowledge that can be applied directly to real-world projects.

Lecture Points 💫

Building the foundation for RAG implementation

Simply following the code has its limitations. You need to understand the principles behind when and why you use each component . This course covers the fundamental concepts of RAG, its main components, and LCEL syntax , laying the foundation for implementing RAG . We also offer a free beginner-friendly course on Python and Langchain.

Improve RAG implementation capabilities with the latest modules and techniques

The RAG process consists of [document loading → text segmentation → embedding → vector storage → search → prompt → LLM → final result]. This lecture introduces various cutting-edge modules and techniques applicable to each process . In particular, you can experience advanced search techniques such as hybrid search, re-rank, and context compression to improve search performance.

10 Performance Evaluations for RAG Improvement

To enhance the RAG system, "evaluation and improvement" is essential. This lecture introduces five information retrieval methods to evaluate RAG's search performance. It also covers five response evaluation methods for RAG, including quantitative indicator-based evaluation methods and LLM-based evaluation methods.

Easy and clear explanations proven by numerous reviews

Many students have proven this

The course reviews are for courses opened by knowledge sharers as of September 24th.

Learn about these things

Understanding the basic concepts of RAG and LangChain

Understand the operating principles of the RAG system, learn LangChain's structure, and learn LCEL syntax. This will prepare you for a practical environment and provide fundamental knowledge that can be applied to various AI projects.

Hands-on : Installing LangChain, setting up the environment, and configuring a basic RAG pipeline.

Practice data processing and text segmentation techniques

You can handle various data formats (PDF, JSON, Web, etc.) and learn effective text segmentation techniques to efficiently manage large-scale data.

Hands-on training : Practice with various document loaders such as PyPDFLoader and CSVLoader, and apply text segmentation strategies (recursive segmentation, regular expression utilization, semantic segmentation).

Utilizing Embedding Models and Vector Storage

You can maximize RAG search performance by leveraging embedding models to convert text data into vectors and store them in a vector storage.

Hands-on training : Creating and searching Chroma and FAISS vector repositories, utilizing OpenAI, Huggingface, and Ollama embedding models.

RAG Search Performance Evaluation and Optimization

Evaluate RAG search performance using various information retrieval evaluation metrics and acquire optimization techniques that can be applied to actual projects.

Practical training : Search performance testing and evaluation (quantitative evaluation such as hit rate and MRR), optimization methods (query expansion, re-rank, context compression)

Generating and evaluating answers using LLM

You can generate answers for the RAG system using various LLMs and evaluate the quality of the answers using the LangChain evaluation tool.

Practice content : LLM integration practice, response evaluation using LangChain evaluation tool

Implementing a RAG-based chatbot using Gradio

Using Gradio, you can build RAG-based chatbot interfaces that interact with users and design real-time search and answer generation systems.

Hands-on : Implementing a RAG chatbot using Gradio, stream-based output, and adding chat history.
