validation_percentage (Дополнительный)	The percentage of training samples that will be used for validating the model. The default value is 10.	Double
stop_training (Дополнительный)	Specifies whether early stopping will be implemented. STOP_TRAINING—Early stopping will be implemented, and the model training will stop when the model is no longer improving, regardless of the max_epochs parameter value specified. This is the default. CONTINUE_TRAINING—Early stopping will not be implemented, and the model training will continue until the max_epochs parameter value is reached.	Boolean
freeze (Дополнительный)	Specifies whether the backbone layers in the pretrained model will be frozen, so that the weights and biases remain as originally designed. FREEZE_MODEL—The backbone layers will be frozen, and the predefined weights and biases will not be altered in the backbone_model parameter. This is the default. UNFREEZE_MODEL—The backbone layers will not be frozen, and the weights and biases of the backbone_model parameter can be altered to fit the training samples. This takes more time to process but typically produces better results.	Boolean
