Hyperparameter

Value

Description

Optimizer

Adam

Optimizer used for the training process.

Loss function

Categorical Cross-Entropy

Loss function to evaluate the model’s predictions against the true labels.

Performance metric

Accuracy

Metric used to assess the model’s performance during training.

Learning rate

Initial or Adaptive

Starting learning rate, adjusted by callbacks during training.

ReduceLROnPlateau factor

0.2

Factor by which the learning rate is reduced when validation loss plateaus.

ReduceLROnPlateau patience

5

Number of epochs with no improvement after which learning rate will be reduced.

ReduceLROnPlateau Min LR

0.001

Minimum learning rate after which it will not reduce further.

EarlyStopping patience

10

Number of epochs with no improvement after which training will be stopped.

EarlyStopping best weights

True

Option to restore the best weights from the training process to prevent overfitting.
