Training

To train the network on the Symmmetric Noise CIFAR-10 dataset (noise rate = 0.7):

$ python first_step_train.py --gpu 0 --out first_sn07 --learnrate 0.08 --alpha 1.2 --beta 0.8 --percent 0.7
$ python second_step_train.py --gpu 0 --out second_sn07 --label first_sn07

To train the network on the Asymmmetric Noise CIFAR-10 dataset (noise rate = 0.4):

$ python first_step_train.py --gpu 0 --out first_an04 --learnrate 0.03 --alpha 0.8 --beta 0.4 --percent 0.4 --asym
$ python second_step_train.py --gpu 0 --out second_an04 --label first_an04
