clear_model()

core_analytics\predictor::clear_model	(		$uniqueid,
			$modelversionoutputdir
	)

Delete all stored information of the current model id.

This method is called when there are important changes to a model, all previous training algorithms using that version of the model should be deleted.

In case you want to perform extra security measures before deleting a directory you can check that $modelversionoutputdir subdirectories can only be named 'execution', 'evaluation' or 'testing'.

Parameters

string	$uniqueid	The site model unique id string
string	$modelversionoutputdir	The output dir of this model version

Return values

null

Implemented in mlbackend_python\processor, and mlbackend_php\processor.

delete_output_dir()

core_analytics\predictor::delete_output_dir	(		$modeloutputdir,
			$uniqueid
	)

Delete the output directory.

This method is called when a model is completely deleted.

In case you want to perform extra security measures before deleting a directory you can check that the subdirectories are timestamps (the model version) and each of this subdirectories' subdirectories can only be named 'execution', 'evaluation' or 'testing'.

Parameters

string	$modeloutputdir	The model directory id (parent of all model versions subdirectories).
string	$uniqueid

Return values

null

Implemented in mlbackend_python\processor, and mlbackend_php\processor.

is_ready()

core_analytics\predictor::is_ready
