Anomaly Python Packages

alibi-detect

Algorithms for outlier, adversarial and drift detection

pysad

Streaming anomaly detection in Python: 16 online detectors (xStream, LODA, RS-Hash, Half-Space Trees, RRCF…) plus calibration and prequential evaluation for real-time data.

detectmatelibrary

Collection of algorithms for log data anomaly detection

oddball

Anomaly Detection Datasets Collection

faster-etapr

Faster implementation of the enhanced time-aware precision and recall (eTaPR) for the evaluation of anomaly detection methods on time series data

frequency-anomaly-reporter

Sliding-window event-frequency monitors that detect anomalous rates - both excessive and insufficient - via configurable thresholds and callbacks. Zero dependencies.

refstat

Distance-based deviation scoring, reference standardisation, and temporal pattern decomposition for small reference sets

telemetry-anomdet

Spacecraft telemetry anomaly detection that runs on flight hardware. Graph deep detectors, label-free thresholding, and distillation to Power of Ten conformant C for microcontrollers.

potoos

Lightweight anomaly detection on RedisTimeSeries using Luminol

tsag

A time series anomaly generation tool for quickly generating anomalies in time series machine learning problems.
