Researchers have developed a novel statistical method for anomaly detection in large vector field datasets, such as those from satellite imagery. This approach utilizes a distribution-free stochastic functional analysis and a multilevel vector field expansion to identify anomalies without assuming specific data distributions. The method was applied to detect forest degradation in the Amazon and demonstrated superior performance over traditional PCA-based techniques, particularly for subtle anomalies. AI
