Five-Region Rough Isolation Forest with Multi-Strategy Feature Optimization for High-Dimensional Anomaly Detection
A high-dimensional anomaly detection model, MSFO-EIF, integrating multi-strategy feature optimization with rough set modeling is proposed, outperforms other anomaly detection models, including KNN, LOF, IBBA-EIF, and RRSM, on multiple high-dimensional datasets.
