Introduction about the codes

Models:

(1) cifar10_train.py implements the classifier directly trained on the dataset.

(2) cifar10_train_T.py implements the loss correction method in https://github.com/giorgiop/loss-correction

(3) cifar10_train_varT.py implements the classifier with adaptation of noise transition.

(4) cifar10_train_GANT.py implements our MASKING model.

Datasets:

(1) The CIFAR-10 dataset can be downloaded and placed in the corresponding position by following the introduction in ./data/cifar-10-batches-bin/readme.txt

(2) The noisy datasets is generated by noise.py based on the clean CIFAR-10 dataset.

You can switch the noisy dataset for cifar10_train_T.py, cifar10_train_varT.py and cifar10_train_GANT.py by setting the NOISE_TYPE parameter in cifar10_input.py

Example:

(1) Due to the requirements of initialization about the noise transition, some codes must be executed in order. For example, you can execute the codes in the following order,

python cifar10_train.py

python cifar10_train_T.py

python cifar10_train_varT.py

python cifar10_train_GANT.py

(2) For evaluation, since the evaluation scripts are separated, you can first launch up the training script and then launch up the evaluation script in another terminal. For example,

python cifar10_train.py --train_dir events/cifar10_train

python cifar10_eval.py --checkpoint_dir events/cifar10_train --eval_dir events/cifar10_eval

These codes are forked from the Tensorflow official CIFARnet in https://github.com/tensorflow/models/tree/master/tutorials/image/cifar10.
