IMLModelTrainer class

Level: advanced

Implements the IMLModelTrainer interface.

Trainer of the prediction model.

Responsible for the overall processing of a single model during the training stage. Communication with the service is provided through a proxy to a predictive service.

Methods

IMLModelTrainer.StartTrainSession()

Sets the training session for the model.

IMLModelTrainer.UploadData()

Transfers the data according to the model selection in packages of 1000 records. The selection is limited to 75,000 records.

IMLModelTrainer.BeginTraining()

Indicates the completion of data transfer and informs the service about the need to put the model in the training queue.

IMLModelTrainer.UpdateModelState()

Requests the service for the current state of the model and updates the Status (if necessary).

If the training was successful (Status contains the Done value), the service returns the properties for the trained instance, particularly the accuracy of the resulting instance. If the precision is greater than or equal to the lower threshold (MetricThreshold), the ID of the new instance is written in the ModelInstanceUId field.
