cusum_anomaly_detector

CUSUM (Cumulative Sum Control Chart) anomaly detector for continuous sequence-like datasets. Learns per-step population mean and standard deviation from baseline training examples, or from the baseline subset of a labeled dataset selected by learn-time class-label options, using a dataset object implementing the anomaly_dataset_protocol protocol. Returns a detector term that can be used for scoring, prediction, and export.
