Static and One-peer exponential graphs comparison on CIFAR-10

Here gives a simple code snippet for running the CIFAR-10 experiments on a decentralized network of size 4 using the one-peer exponential graph. You can find the script for testing in run.sh as well.

$ bfrun -np 4 python train_cifar10.py --epochs 200 --model resnet56 --batch-size 128 --base-lr 0.01

Expected performance on CIFAR-10 experiments

Method Accuracy
Static exponential graph 91.21%
One-peer exponential graph 91.84%
