Streamlit Applications Hub

🚀 About This Project

A curated hub of interactive Streamlit applications showcasing practical AI and data science. Each app is designed for clarity, fast iteration, and hands-on exploration.

📋 Key Features

• 📊 Stock Screener: AI-assisted equity research with indicators, charts, and reports
• 🗺️ Airbnb Tour Agent (MCP + Weather): Trip plans from Airbnb listings + weather via MCP
• 📖 HarryAgent: LLM multi-agent research and writing with retrieval + critique loop
• 🎯 Logo Detection: YOLO-based logo recognition
• 📈 Clustering: Interactive clustering demos (KMeans/DBSCAN)
• 🧠 Image Classifier: Multi-backbone image classification

📚 Project Details

📊 AI Stock Screener

• Real-time price data via yfinance
• Fundamentals/shareholding scraped from screener.in
• News context via GNews
• Technical indicators: EMA, SMA, RSI, MACD; breakout heuristics
• Interactive tables and charts (mlpchart)
• AI stock research report powered by ChatGroq

🗺️ Airbnb Tour Agent (MCP + Weather)

• LangGraph composition: parallel weather agent + Airbnb MCP agent → tour synthesis
• MCP stdio to @openbnb/mcp-server-airbnb via npx
• Weather tool formats a concise forecast report
• Streams tour synthesis updates to the UI
• Uses system Node 20 or bundled nodev20/ for reliable MCP execution

📖 HarryAgent (LLM multi-agent, RAG + critique)

• Thematic blend: Harry Potter × Indian Mythology
• LangGraph workflow: classify → researcher → mythologist → writer → critic (with loop)
• Retrieval via FAISS index in HPVdb/ with CrossEncoder reranking
• Checkpointing in SQLite; observability via Langfuse

🧠 Image Classifier

• Multiple backbones: Xception, InceptionV3, MobileNetV2, EfficientNet
• Loads checkpoints (*.ckpt) and runs per-model inference
• Displays per-model metrics for comparison

🎯 Logo Detection

• Ultralyics YOLO-based logo recognition with bundled weights (LogoYolobest.pt)
• Integrated into the app via shared utilities
• Real-time inference on uploaded images

📈 Clustering

• KMeans and DBSCAN demos with synthetic data
• Interactive visualizations with seaborn/matplotlib
• K-distance graph to explore cluster structure
