Train Wide-ResNet, Shake-Shake and ShakeDrop models on CIFAR-10 and CIFAR-100 dataset with AutoAugment.
The CIFAR-10/CIFAR-100 data can be downloaded from: https://www.cs.toronto.edu/~kriz/cifar.html. Use the Python version instead of the binary version.
The code replicates the results from Tables 1 and 2 on CIFAR-10/100 with the following models: Wide-ResNet-28-10, Shake-Shake (26 2x32d), Shake-Shake (26 2x96d) and PyramidNet+ShakeDrop.

Prerequisite:
-
Install TensorFlow. Be sure to run the code using python2 and not python3.
-
Download CIFAR-10/CIFAR-100 dataset.

curl -o cifar-100-binary.tar.gz https://www.cs.toronto.edu/~kriz/cifar-100-python.tar.gzHow to run:
# cd to the your workspace.
# Specify the directory where dataset is located using the data_path flag.
# Note: User can split samples from training set into the eval set by changing train_size and validation_size.
# For example, to train the Wide-ResNet-28-10 model on a GPU.
