PropertyDescription
<model storage-location>

ML model storage location is either the file system or Registry. If the model is stored in the Registry, storage-location should have the prefix registry:

<percentile value>Percentile The percentile value for the prediction. This should be a double value between 0-100. 95.0 is default. It is required to specify a percentile value when the ML model uses an algorithm of the Anomaly Detection type. This property is optional for other algorithm types. For more information about algorithms of the Anomaly Detection type, see Machine Learner Algorithms.
<name>Name of the feature according to the generated model.
<expression>The XPath or JSONPath expression to extract the feature value from the payload.
<predictionOutput property>
The message context property name, to which you need to set the prediction output value.
