| # 🔍 RAG Pipeline For LLMs 🚀 | |
| [](https://huggingface.co/spaces/Mehardeep7/rag-pipeline-llm) | |
| [](https://python.org) | |
| ## 📖 Project Overview | |
| An intelligent **Retrieval-Augmented Generation (RAG)** pipeline that combines semantic search with question-answering capabilities. This system fetches Wikipedia articles, processes them into searchable chunks, and uses state-of-the-art AI models to provide accurate, context-aware answers. | |
| ## ✨ Key Features | |
| - 📚 **Dynamic Knowledge Retrieval** from Wikipedia with error handling | |
| - 🧮 **Semantic Search** using sentence transformers (no keyword dependency) | |
| - ⚡ **Fast Vector Similarity** with FAISS indexing (sub-second search) | |
| - 🤖 **Intelligent Answer Generation** using pre-trained QA models | |
| - 📊 **Confidence Scoring** for answer quality assessment | |
| - 🎛️ **Customizable Parameters** (chunk size, retrieval count, overlap) | |
| - ✂️ **Smart Text Chunking** with overlapping segments for context preservation | |
| ## 🏗️ Architecture | |
| ``` | |
| User Query → Embedding → FAISS Search → Retrieve Chunks → QA Model → Answer + Confidence | |
| ``` | |
| ## 🤖 AI Models Used | |
| - **📏 Text Chunking**: `sentence-transformers/all-mpnet-base-v2` tokenizer | |
| - **🧮 Vector Embeddings**: `sentence-transformers/all-mpnet-base-v2` (768-dimensional) | |
| - **❓ Question Answering**: `deepset/roberta-base-squad2` (RoBERTa fine-tuned on SQuAD 2.0) | |
| - **🔍 Vector Search**: FAISS IndexFlatL2 for L2 distance similarity | |
| ## 🚀 How to Use | |
| 1. **📖 Process Article**: Enter any Wikipedia topic and configure chunk settings | |
| 2. **❓ Ask Questions**: Switch to Q&A tab and enter your questions | |
| 3. **📊 View Results**: Explore answers with confidence scores and similarity metrics | |
| 4. **🔍 Analyze**: Check retrieved context and visualization analytics | |
| ## 💡 Example Usage | |
| ``` | |
| Topic: "Artificial Intelligence" | |
| Question: "What is machine learning?" | |
| Answer: "Machine learning is a subset of artificial intelligence..." | |
| Confidence: 89.7% | |
| ``` | |
| ## 🔧 Configuration Options | |
| - **Chunk Size**: 128-512 tokens (default: 256) | |
| - **Overlap**: 10-50 tokens (default: 20) | |
| - **Retrieval Count**: 1-10 chunks (default: 3) | |
| ## 📊 Performance | |
| - **Search Speed**: Sub-second retrieval for 1000+ chunks | |
| - **Accuracy**: High precision with confidence scoring | |
| - **Memory Efficient**: Optimized chunk sizes prevent token overflow | |
