Padam vs ATMO

This code is a fork of Padam offical code to obtain a perfect comparison between ATMO idea and Padam.

Prerequisites:

pip install -r requirements.txt

Usage:

Use python to run run_cnn_test_cifar10.py for experiments on Cifar10 and run_cnn_test_cifar100.py for experiments on Cifar100

Command Line Arguments:

• --lr: (start) learning rate
• --method: optimization method, e.g., "sgdm", "adam", "amsgrad", "padam", "mps", "mas", "map"
• --net: network architecture, e.g. "vggnet", "resnet", "wideresnet"
• --partial: partially adaptive parameter for Padam method
• --wd: weight decay
• --Nepoch: number of training epochs
• --resume: whether resume from previous training process

Usage Examples:

• Run experiments on Cifar10:

python run_cnn_test_cifar10.py  --lr 0.01 --method "mps" --net "resnet"  --partial 0.125 --wd 2.5e-2 > logs/resnet/file.log

• Obtain max and mean of logs

python folder_mean_accuracy.py
