Datasets manager.__construct($modelid, $analysableid, $timesplittingid, $filearea, $evaluation = false) X-Ref |
Constructor method. param: int $modelid param: int $analysableid param: string $timesplittingid param: string $filearea param: bool $evaluation return: void |
store($data) X-Ref |
Store the dataset in the internal file system. param: array $data return: \stored_file |
get_previous_evaluation_file($modelid, $timesplittingid) X-Ref |
Returns the previous evaluation file. Important to note that this is per modelid + timesplittingid, when dealing with multiple analysables this is the merged file. Do not confuse with self::get_evaluation_analysable_file param: int $modelid param: string $timesplittingid return: \stored_file |
get_pending_files($modelid, $includetarget, $timesplittingids) X-Ref |
Gets the list of files that couldn't be previously used for training and prediction. param: int $modelid param: bool $includetarget param: string[] $timesplittingids return: null |
delete_previous_evaluation_file($modelid, $timesplittingid) X-Ref |
Deletes previous evaluation files of this model. param: int $modelid param: string $timesplittingid return: bool |
get_evaluation_analysable_file($modelid, $analysableid, $timesplittingid) X-Ref |
Returns this (model + analysable + time splitting) file. param: int $modelid param: int $analysableid param: string $timesplittingid return: \stored_file |
merge_datasets(array $files, $modelid, $timesplittingid, $filearea, $evaluation = false) X-Ref |
Merge multiple files into one. Important! It is the caller responsability to ensure that the datasets are compatible. param: array $files param: int $modelid param: string $timesplittingid param: string $filearea param: bool $evaluation return: \stored_file |
export_training_data($modelid, $timesplittingid) X-Ref |
Exports the model training data. param: int $modelid param: string $timesplittingid return: \stored_file|false |
get_structured_data(\stored_file $dataset) X-Ref |
Returns the dataset file data structured by sampleids using the indicators and target column names. param: \stored_file $dataset return: array |
clear_model_files($modelid) X-Ref |
Delete all files of a model. param: int $modelid return: bool |
get_filename($evaluation) X-Ref |
Returns the file name to be used. param: strinbool $evaluation return: string |
