Researchers have developed a novel anomaly detection method designed for high-dimensional datasets containing mixed data types. This approach, termed the Mixed-data Influence (MDI) score, standardizes heterogeneous features to a common scale using moment-based transformations. The MDI score then aggregates these transformed features in a dependence-aware manner, accounting for correlations and providing interpretable, feature-level anomaly scores. This method can identify anomalies stemming from location shifts, as well as changes in variability, skewness, and other distributional characteristics, and is applicable to both sparse and distributed deviations across features.
