CIFAR-100 WideResNet 40-4

class deepobs.tensorflow.testproblems.cifar100_wrn404.cifar100_wrn404(batch_size, weight_decay=0.0005)

DeepOBS test problem class for the Wide Residual Network 40-4 architecture for CIFAR-100.

Details about the architecture can be found in the original paper. A weight decay is used on the weights (but not the biases) which defaults to 5e-4.

Training settings recommenden in the original paper: batch size = 128, num_epochs = 200 using the Momentum optimizer with \(\mu = 0.9\) and an initial learning rate of 0.1 with a decrease by 0.2 after 60, 120 and 160 epochs.

Parameters:

• batch_size (int) -- Batch size to use.
• weight_decay (float) -- Weight decay factor. Weight decay (L2-regularization) is used on the weights but not the biases. Defaults to 5e-4.
