The hyperparameters for training image classifiers.

Inherits From: HParams

learning_rate Learning rate to use for gradient descent training.
batch_size Batch size for training.
epochs Number of training iterations over the dataset.
do_fine_tuning If true, the base module is trained together with the classification layer on top.
l1_regularizer A regularizer that applies a L1 regularization penalty.
l2_regularizer A regularizer that applies a L2 regularization penalty.
label_smoothing Amount of label smoothing to apply. See tf.keras.losses for more details.
do_data_augmentation A boolean controlling whether the training dataset is augmented by randomly distorting input images, including random cropping, flipping, etc. See utils.image_preprocessing documentation for details.
decay_samples Number of training samples used to calculate the decay steps and create the training optimizer.
warmup_steps Number of warmup steps for a linear increasing warmup schedule on learning rate. Used to set up warmup schedule by model_util.WarmUp.s
