👨‍💻 Tutorial Breakdown:
Part 1: AI Training with Web Data
1. Web Scraping with Puppeteer: Leverage Puppeteer and the PuppeteerWebBaseLoader from LangChain for efficient web data scraping.
2. Data Cleaning with Cheerio: Utilize Cheerio library to clean HTML code and ASCII characters, preparing text data for processing.
3. Text Splitting: Employ the RecursiveCharacterTextSplitter from LangChain to segment text data, optimizing it for AI training.
4. Vector Embedding Creation: Process the cleaned and split data through OpenAI's Embedding function to generate vector embeddings.
5. Faiss Vector Store Creation: Compile the vector embeddings into a Faiss vector data store for efficient retrieval.
Part 2: RAG Chatbot Development
1. RAG Chatbot UI/UX: Present the RAG chatbot interface using React components, styled with Tailwind CSS and SCSS modules for a polished user experience.
2. Custom Hook for Frontend Communication: Implement a modular custom hook to facilitate communication between the frontend and Next.js backend, enabling streaming text display on the web interface.
3. Retrieval QA Chain Setup: Configure the Next.js backend API to create a Retrieval QA Chain, utilizing the Faiss Vector Store as the data retriever.
4. Contextual AI Responses: Invoke the QA Chain with user prompts to generate contextual answers from the OpenAI API, leveraging the trained AI for insightful, accurate responses.
