COLD_START
Adds a ColdStart
label to anomalies that occur at the beginning of the dataset. Used to filter anomalies until
the detection model has enough historical data.
The start of the dataset is obtained by looking at the minimum time value in the Pinot main time column.
The cold start period is defined as [start, start + coldStartPeriod]
. coldStartPeriod
is configurable.
Inputs
- The output of the detector. Labels are applied to the anomalies of this input.
{
"sourcePlanNode": "anomalyDetector"
}
Parameters
name | description | default value |
---|---|---|
component.coldStartPeriod | Cold start period. In ISO-8601 format. Eg P7D . If the anomaly is in [start, start + Period], label the anomaly. | |
component.tableName | Table to look at to find the start. Eg my_dataset . |
