## CIFAR100 dataset with long tail distribution
Modified by Jonghyun Choi (2021.5.23)

*Disclaimer*: This dataset is not the same to the CIFAR100-LT dataset you can download from the web.

## Note
1. Filenames are all randomized.
1. Some of the training samples' label are randomized for the noisy label
1. Testing samples' label are *not* randomized
1. Number of samples for training and testing are the same to the CIFAR100 dataset (except two files (one for training and one for testing) are removed from the original dataset for the duplicated label)
1. Now, labels of the testing samples are removed for submission.
1. Unlike the dataset for CA1 and CA2, number of samples per class is all different.

### To use the dataset for the best test accuracy, plz do either
1. Split the training set into training and validation
2. Use cross validation
