TSADmetrics - Time Series Anomaly Detection Metrics

TSADmetrics is a Python library for evaluating anomaly detection algorithms in time series data.
It provides a comprehensive set of metrics specifically designed to handle the temporal nature of anomalies.

---

Key features

• Metric Taxonomy: Metrics are categorized into types based on how they handle temporal context:

  • SPM Metrics: Evaluate predictions at each point independently, ignoring temporal continuity.
  • TEM Metrics: Consider temporal context, analyzing when and how anomalies occur.
    • TPDM: Partial detection within a real anomaly event counts as correct.
    • PTDM: Requires detection to cover a significant fraction of the real anomaly.
    • TMEM: Measures alignment of real vs predicted anomaly events.
    • DPM: Penalizes late detections.
    • TSTM: Allows temporal tolerance for early or late detections.

• Direct Metric Usage: Instantiate any metric class and call compute() for individual evaluation.

• Batch Evaluation: Use Runner to evaluate multiple datasets and metrics at once, with support for both direct data and CSV/JSON input.

• Flexible Configuration: Load metrics from YAML configuration files or global evaluation config files.
