GNN + LLM Integration for Stock Portfolio Optimization
Designed and implemented a GraphSAGE-based GNN using PyTorch to model relationships between Nifty-50 stocks using financial and textual features. Integrated FinBERT for sentiment extraction and Mistral-7B for reasoning-based portfolio scoring. Built end-to-end ML pipeline including data preprocessing, feature engineering, model training with gradient optimization, and backtesting. Documented methodology as a formal M.Sc. thesis and IEEE/APA research article.
