📊 SmartPortfolio

Intelligent Portfolio Optimization using Graph Neural Networks, Prophet Forecasting, and Deep Reinforcement Learning

---

🚀 Overview

SmartPortfolio is a terminal-based portfolio optimization system that combines cutting-edge machine learning techniques to generate intelligent asset allocations:

• 🔗 Graph Neural Networks (GAT) — Model complex asset relationships and correlations
• 📈 Prophet Forecasting — Time series predictions with seasonality awareness
• 🤖 Deep Reinforcement Learning (PPO) — Dynamic allocation via hierarchical agents
• 💻 Neural Terminal TUI — Beautiful, Bloomberg-inspired terminal interface

✨ Features

Feature	Description
PyTorch GAT	Pure PyTorch Graph Attention Network for asset embeddings
Correlation Graphs	Dynamic asset relationship visualization
Live Prices	Real-time market data via yfinance
Portfolio Metrics	Expected return, volatility, Sharpe ratio
Plot Export	Save allocation charts (pie, bar, dashboard)
8GB RAM Optimized	Memory-efficient for consumer hardware
