🤖 InsightRAG Chatbot: ML/AI Knowledge Assistant

A fully functional Retrieval-Augmented Generation (RAG) chatbot that provides comprehensive information about machine learning, deep learning, AI, and related topics. Built with modern AI technologies and ready for deployment.

🎯 Project Purpose

This RAG chatbot serves as an intelligent knowledge assistant specializing in machine learning, deep learning, and artificial intelligence topics. The chatbot leverages a sophisticated retrieval-augmented generation pipeline to provide accurate, contextual answers by combining:

• Knowledge Retrieval: Accessing relevant information from a curated ML/AI knowledge base
• Contextual Generation: Using Google Gemini 2.5 Flash to generate comprehensive responses
• Interactive Learning: Enabling users to explore complex AI concepts through natural conversation

The primary goal is to make AI and machine learning knowledge accessible through an intuitive, conversational interface that can handle both basic concepts and advanced technical questions.

📚 Dataset Information

Dataset Source

• Primary Dataset: The Pile (EleutherAI/the_pile) from Hugging Face
• Access Method: Hugging Face Datasets API (no local downloads required)
• Content Type: Text-only data (no tables, images, or PDFs)

Dataset Structure

The dataset contains diverse text content filtered specifically for ML/AI relevance:

• Content Filtering: Text samples are filtered using ML/AI keywords including:

  • Machine learning, deep learning, neural networks
  • Artificial intelligence, algorithms, models
  • Training, data, features, classification
  • Regression, clustering, optimization, gradient, tensor

• Text Processing:

  • Content is cleaned and preprocessed
  • Text is chunked into manageable pieces (500 words with 50-word overlap)
  • Only substantial chunks (100-2000 characters) are retained
  • Text is embedded using sentence transformers for vector search

• Storage: Processed text chunks are stored in Chroma vector database for efficient similarity search

Usage in RAG Pipeline

The dataset serves as the knowledge base for the RAG system, enabling:

• Semantic search for relevant context
• Contextual answer generation
• Comprehensive coverage of ML/AI topics

🔧 Methods Used

RAG Pipeline Architecture

The chatbot implements a sophisticated Retrieval-Augmented Generation pipeline:

Raw Text → Filtering → Chunking → Embedding → Vector Storage

• Text Filtering: ML/AI keyword-based content selection
• Chunking: Intelligent text segmentation with overlap
• Embedding: Sentence transformer-based vectorization
• Storage: Chroma vector database for efficient retrieval

2. Retrieval System

• Embedding Model: all-MiniLM-L6-v2 (sentence-transformers)
• Vector Database: Chroma with persistent storage
• Similarity Search: Cosine similarity for document retrieval
• Context Assembly: Top-k relevant documents combined

3. Generation System

• Language Model: Google Gemini 2.5 Flash
• Temperature: 0.7 for balanced creativity and accuracy
• Context Integration: Retrieved documents used as context
• Response Formatting: Markdown support for rich text

4. Technical Stack

• RAG Framework: LangChain for pipeline orchestration
• Vector Database: Chroma for embedding storage and retrieval
• Embeddings: Sentence Transformers for text vectorization
• LLM: Google Gemini 2.5 Flash for response generation
• Interface: Streamlit for web-based chat interface
