Recursive Feature Elimination

Algorithm

Recursive Feature Elimination (RFE) represents an iterative process applied within quantitative financial modeling, specifically for feature selection in predictive models used for cryptocurrency price forecasting, options pricing, and derivative valuation. It operates by repeatedly training a model—often a regression or classification algorithm—and ranking features based on their importance, subsequently eliminating the least significant ones in each iteration. This iterative reduction aims to identify the optimal subset of features that maximize model performance and minimize overfitting, crucial when dealing with the high dimensionality and noise inherent in financial time series data. The process continues until a predefined number of features remains, or performance plateaus, providing a parsimonious model suitable for real-time trading strategies and risk management.
