IMLModelTrainerJob class

Level: advanced

Implements the IJobExecutor and IMLModelTrainerJob interfaces.

It is used for model synchronization tasks.

Orchestrates model processing on the side of Creatio by launching data transfer sessions, starting trainings, and also checking the status of the models processed by the service. Instances are launched by default by the task scheduler through the standard Execute method of the IJobExecutor interface.

Methods​

IMLModelTrainerJob.RunTrainer()

A virtual method that encapsulates the synchronization logic. The base implementation of this method performs the following actions:

  1. Selecting models for training – the records are selected from MLModel based on the following filter:

    • The MetaData and TrainingSetQuery fields are populated.
    • The Status field is not in the NotStarted, Done or Error state (or not populated at all).
    • TrainFrequency is more than 0.
    • The TriedToTrainOn days have passed since the last training date (TrainFrequency).
      For each record of this selection, the data is sent to the service with the help of the predictive model trainer.

  2. Selecting previously trained models and updating their status (if necessary).

The data transfer session for the selection starts for each suitable model. The data is sent in packages of 1000 records during the session. For each model, the selection size is limited to 75,000 records.
