Connecting a Raspberry Pi to Ubuntu when Using a VPN and Sharing the Internet Connection
In a couple of previous posts, I showed how you can connect a Raspberry Pi to Ubuntu using a direct Ethernet cable, no need for a router, switch, or wifi. But if you have a VPN on the Ubuntu machine, you may need to take a few extra steps to get the Raspberry Pi connected.

EP230: RAG vs Agentic RAG
RAG (Retrieval-Augmented Generation) và Agentic RAG là hai phương pháp xử lý thông tin khác nhau trong lĩnh vực AI. RAG hoạt động bằng cách truy vấn vector database để tìm thông tin liên quan trước khi tạo câu trả lời, ví dụ như với vector database có thể chứa hàng triệu document embeddings. Agentic RAG thêm vào một agent có khả năng tự suy luận, cho phép hệ thống tự động xác định cần tìm thêm thông tin hay không, như trường hợp của OpenAI's GPT-4 với function calling. Sự khác biệt chính là Agentic RAG có khả năng tự chủ trong việc quyết định cần làm gì tiếp theo thay vì chỉ phụ thuộc vào kết quả truy vấn ban đầu. Đây là kiến thức quan trọng để hiểu sự tiến hóa từ RAG cơ bản đến các hệ thống thông minh hơn có khả năng tự điều chỉnh.
Bài viết này giúp bạn hiểu rõ sự khác biệt cơ bản giữa RAG và Agentic RAG để áp dụng hiệu quả vào các dự án AI.
