UPDATE MODEL

Syntax:

UPDATE MODEL model_name USING method_name FROM input_stream

Example:

jubaql> UPDATE MODEL cls USING train FROM ds
UPDATE MODEL

Explanation

UPDATE MODEL connects a stream with a model: When stream processing is started, the model will be updated with all items in the stream using the given method and the feature extractor attached to the model.

• model_name is the name of a model previously defined using CREATE MODEL.
• method_name is the method to use for updating the model:
  • add for an ANOMALY model,
  • train for a CLASSIFIER model,
  • update_row for a RECOMMENDER model.
• input_stream is the stream to use as input. The data source that this stream is derived from must not yet be in process (or done with processing) when the statement is issued.
