Researchers have developed ReForest, a new framework that combines the statistical efficiency of Isolation Forest with the semantic reasoning capabilities of large language models (LLMs). This approach aims to improve anomaly detection by transforming Isolation Forest's decision paths into natural-language explanations that LLMs can refine. ReForest uses an uncertainty-aware dynamic ensemble to adaptively weigh statistical and semantic signals, leading to significant performance gains in detection accuracy and interpretability. Experiments on real-world datasets showed an average 21% improvement in Recall and a 10% gain in F1-score, providing interpretable rationales for high-stakes decisions. AI
