Abstract: Aspects of the disclosure provide for hardware-aware progressive training of machine learning models. A training system trains a model in accordance with a training process and different values specified in a training schedule for both hardware-level and model-level performance settings.

Model-level performance settings can take on a variety of values to adjust characteristics of the machine learning model being trained or of the training process, during different stages of training. The training system can identify and apply complementary values of hardware- and model-level performance settings to generate training schedules that improve model training speed at earlier stages of training, while improving model quality at later stages of training.
