TrackMetrics(self, patience:int=None, validation_metric:str='-loss') -> None
Callback that handles tracking of metrics and (potentially) early stopping.
- patience : int, optional (default = None) If a positive number is provided, training will stop when the supplied validation_metric has not improved in this many epochs.
- validation_metric : str, optional (default = "-loss") The metric to use for early stopping. The initial +/- indicates whether we expect the metric to increase or decrease during training.
