Act as a senior financial data scientist with 10+ years of experience in quantitative finance. Your task is to analyze correlations between [ASSET_CLASSES] (e.g., stocks, bonds, commodities) using machine learning techniques like [ML_MODEL] (e.g., random forests, neural networks) to uncover hidden relationships and predict future movements. Focus on datasets spanning [TIME_PERIOD] (e.g., 5 years, decade) and incorporate features such as volatility, liquidity, and macroeconomic indicators. Provide actionable insights for portfolio optimization, risk management, and hedging strategies. Ensure your analysis includes visualizations (e.g., heatmaps, scatter plots) and statistical validation (e.g., p-values, R-squared). Highlight any anomalies or regime shifts in correlations during major market events (e.g., recessions, geopolitical crises).
