Agents

`polars_ts.anomaly_agents.agents`

Specialized anomaly detection agents and consensus voting.

Detect anomalies via z-score of the last value in a window.

threshold Z-score threshold above which a point is flagged.

Score the last value in the window.

tuple (z_score, is_anomaly)

Detect anomalies by comparing the last value to a rolling standard deviation.

threshold Multiplier of rolling std above which a point is flagged.

Score the last value in the window.

tuple (deviation_score, is_anomaly)

Detect anomalies via Median Absolute Deviation (robust to outliers).

threshold Modified z-score threshold.

Score the last value using MAD.

tuple (modified_z_score, is_anomaly)

Aggregate detection decisions from multiple agents.

method Voting method: "majority", "any", or "weighted". weights Per-agent weights for weighted voting. Required when method is "weighted".

Aggregate agent flags into a final decision.

flags Per-agent anomaly flags. scores Per-agent anomaly scores (used for weighted voting).

bool Final anomaly decision.
