Padam

This repository contains our pytorch implementation of Partially Adaptive Momentum Estimation method (Padam) in the paper Closing the Generalization Gap of Adaptive Gradient Methods in Training Deep Neural Networks (accepted by IJCAI 2020).

Prerequisites:

• Pytorch
• CUDA

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"
• --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 0.1 --method "padam" --net "vggnet"  --partial 0.125 --wd 5e-4

• Run experiments on Cifar100:

  -  python run_cnn_test_cifar100.py  --lr 0.1 --method "padam" --net "resnet"  --partial 0.125 --wd 5e-4
