Class ModelCheckpoint

Save the model after every epoch. filepath can contain named formatting options, which will be filled with the values of epoch and keys in logs(passed in on_epoch_end). For example: if filepath is weights.{epoch:02d}-{val_loss:.2f}.hdf5, then the model checkpoints will be saved with the epoch number and the validation loss in the filename.

ModelCheckpoint(String, String, Int32, Boolean, Boolean, String, Int32)

Initializes a new instance of the ModelCheckpoint class.

Declaration
public ModelCheckpoint(string filepath, string monitor = "val_loss", int verbose = 0, bool save_best_only = true, bool save_weights_only = false, string mode = "auto", int period = 1)
Parameters
Type Name Description
System.String filepath

string, path to save the model file.
System.String monitor

quantity to monitor.
System.Int32 verbose

verbosity mode, 0 or 1.
System.Boolean save_best_only

if save_best_only=True, the latest best model according to the quantity monitored will not be overwritten.
System.Boolean save_weights_only

if True, then only the model's weights will be saved (model.save_weights(filepath)), else the full model is saved (model.save(filepath)).
System.String mode

one of {auto, min, max}. If save_best_only=True, the decision to overwrite the current save file is made based on either the maximization or the minimization of the monitored quantity. For val_acc, this should be max, for val_loss this should be min, etc. In auto mode, the direction is automatically inferred from the name of the monitored quantity.
System.Int32 period

Interval (number of epochs) between checkpoints.
